+Database replica settings
+-------------------------
+
+If you use a replicated database setup, pretix expects that the default database connection always points to the primary database node.
+Routing read queries to a replica on database layer is **strongly** discouraged since this can lead to inaccurate such as more tickets
+being sold than are actually available.
+
+However, pretix can still make use of a database replica to keep some expensive queries with that can tolerate some latency from your
+primary database, such as backend search queries. The ``replica`` configuration section can have the same settings as the ``database``
+section (except for the ``backend`` setting) and will default back to the ``database`` settings for all values that are not given. This
+way, you just need to specify the settings that are different for the replica.

+Additional database indices
+===========================
+
+If you have a large pretix database, some features such as search for orders or events might turn pretty slow.
+For PostgreSQL, we have compiled a list of additional database indexes that you can add to speed things up.
+Just like any index, they in turn make write operations insignificantly slower and cause the database to use
+more disk space.
+
+The indexes aren't automatically created by pretix since Django does not allow us to do so only on PostgreSQL
+(and they won't work on other databases). Also, they're really not necessary if you're not having tens of
+thousands of records in your database.
+
+However, this also means they won't automatically adapt if some of the referred fields change in future updates of pretix
+and you might need to re-check this page and change them manually.
+
+Here is the currently recommended set of commands::
+
+    CREATE EXTENSION pg_trgm;

+
+To use the latest development version with Docker, first pull it from Docker Hub::
+
+    $ docker pull pretix/standalone:latest
+
+
+Then change your ``/etc/systemd/system/pretix.service`` file to use the ``:latest`` tag instead of ``:stable`` as well

+
+Installing pretix Enterprise plugins
+====================================
+
+If you want to use a feature of pretix that is part of our commercial offering pretix Enterprise, you need to follow
+some extra steps. Installation works similar to normal pretix plugins, but involves a few extra steps.
+
+Buying the license
+------------------
+
+To obtain a license, please get in touch at sales@pretix.eu. Please let us know how many tickets you roughly intend
+to sell per year and how many servers you want to use the plugin on. We recommend having a look at our `price list`_
+first.
+
+
+Manual installation
+-------------------
+
+First, generate an SSH key for the system user that you install pretix as. In our tutorial, that would be the user
+``pretix``. Choose an empty passphrase::
+
+    # su pretix
+    $ ssh-keygen
+    Generating public/private rsa key pair.
+    Enter file in which to save the key (/var/pretix/.ssh/id_rsa):
+    Enter passphrase (empty for no passphrase):
+    Enter same passphrase again:
+    Your identification has been saved in /var/pretix/.ssh/id_rsa.
+    Your public key has been saved in /var/pretix/.ssh/id_rsa.pub.
+
+Next, send the content of the *public* key to your sales representative at pretix::
+
+    $ cat /var/pretix/.ssh/id_rsa.pub
+    ssh-rsa AAAAB3N...744HZawHlD pretix@foo
+
+After we configured your key in our system, you can install the plugin directly using ``pip`` from the URL we told
+you, for example::
+
+    $ source /var/pretix/venv/bin/activate
+    (venv)$ pip3 install -U "git+ssh://git@code.rami.io:10022/pretix/pretix-slack.git@stable#egg=pretix-slack"
+    (venv)$ python -m pretix migrate
+    (venv)$ python -m pretix rebuild
+    # systemctl restart pretix-web pretix-worker
+
+Docker installation
+-------------------
+
+To install a plugin, you need to build your own docker image. To do so, create a new directory to work in. As a first
+step, generate a new SSH key in that directory to use for authentication with us::
+
+    $ cd /home/me/mypretixdocker
+    $ ssh-keygen -N "" -f id_pretix_enterprise
+
+Next, send the content of the *public* key to your sales representative at pretix::
+
+    $ cat id_pretix_enterprise.pub
+    ssh-rsa AAAAB3N...744HZawHlD pretix@foo
+
+After we configured your key in our system, you can add a ``Dockerfile`` in your directory that includes the newly
+generated key and installs the plugin from the URL we told you::
+
+    FROM pretix/standalone:stable
+    USER root
+    COPY id_pretix_enterprise /root/.ssh/id_rsa
+    COPY id_pretix_enterprise.pub /root/.ssh/id_rsa.pub
+    RUN chmod -R 0600 /root/.ssh && \
+        mkdir -p /etc/ssh && \
+        ssh-keyscan -t rsa -p 10022 code.rami.io >> /root/.ssh/known_hosts && \
+        echo StrictHostKeyChecking=no >> /root/.ssh/config && \
+        DJANGO_SETTINGS_MODULE=pretix.settings pip3 install -U "git+ssh://git@code.rami.io:10022/pretix/pretix-slack.git@stable#egg=pretix-slack" && \
+        cd /pretix/src && \
+        sudo -u pretixuser make production
+    USER pretixuser
+
+Then, build the image for docker::
+
+    $ docker build -t mypretix
+
+You can now use that image ``mypretix`` instead of ``pretix/standalone:stable`` in your ``/etc/systemd/system/pretix.service``
+service file. Be sure to re-build your custom image after you pulled ``pretix/standalone`` if you want to perform an
+update to a new version of pretix.

+
+Scaling guide
+=============
+
+Our :ref:`installation guide <installation>` only covers "small-scale" setups, by which we mostly mean
+setups that run on a **single (virtual) machine** and do not encounter large traffic peaks.
+
+We do not offer an installation guide for larger-scale setups of pretix, mostly because we believe that
+there is no one-size-fits-all solution for this and the desired setup highly depends on your use case,
+the platform you run pretix on, and your technical capabilities. We do not recommend trying set up pretix
+in a multi-server environment if you do not already have experience with managing server clusters.
+
+This document is intended to give you a general idea on what issues you will encounter when you scale up
+and what you should think of.
+
+.. tip::
+
+   If you require more help on this, we're happy to help. Our pretix Enterprise support team has built
+   and helped building, scaling and load-testing pretix installations at any scale and we're looking
+   forward to work with you on fine-tuning your system. If you intend to sell **more than a thousand
+   tickets in a very short amount of time**, we highly recommend reaching out and at least talking this
+   through. Just get in touch at sales@pretix.eu!
+
+Scaling reasons
+---------------
+
+There's mainly two reasons to scale up a pretix installation beyond a single server:
+
+* **Availability:** Distributing pretix over multiple servers can allow you to survive failure of one or more single machines, leading to a higher uptime and reliability of your system.
+
+* **Traffic and throughput:** Distributing pretix over multiple servers can allow you to process more web requests and ticket sales at the same time.
+
+You are very unlikely to require scaling for other reasons, such as having too much data in your database.
+
+Components
+----------
+
+A pretix installation usually consists of the following components which run performance-relevant processes:
+
+* ``pretix-web`` is the Django-based web application that serves all user interaction.
+
+* ``pretix-worker`` is a Celery-based application that processes tasks that should be run asynchronously outside of the web application process.
+
+* A **SQL database** keeps all the important data and processes the actual transactions. We recommend using PostgreSQL, but MySQL/MariaDB works as well.
+
+* A **web server** that terminates TLS and HTTP connections and forwards them to ``pretix-web``. In some cases, e.g. when serving static files, the web servers might return a response directly. We recommend using ``nginx``.
+
+* A **redis** server responsible for the communication between ``pretix-web`` and ``pretix-worker``, as well as for caching.
+
+* A directory of **media files** such as user-uploaded files or generated files (tickets, invoices, …) that are created and used by ``pretix-web``, ``pretix-worker`` and the web server.
+
+In the following, we will discuss the scaling behavior of every component individually. In general, you can run all of the components
+on the same server, but you can just as well distribute every component to its own server, or even use multiple servers for some single
+components.
+
+.. warning::
+
+   When setting up your system, don't forget about security. In a multi-server environment,
+   you need to take special care to ensure that no unauthorized access to your database
+   is possible through the network and that it's not easy to wiretap your connections. We
+   recommend a rigorous use of firewalls and encryption on all communications. You can
+   ensure this either on an application level (such as using the TLS support in your
+   database) or on a network level with a VPN solution.
+
+Web server
+""""""""""
+
+Your web server is at the very front of your installation. It will need to absorb all of the traffic, and it should be able to
+at least show a decent error message, even when everything else fails. Luckily, web servers are really fast these days, so this
+can be achieved without too much work.
+
+We recommend reading up on tuning your web server for high concurrency. For nginx, this means thinking about the number of worker
+processes and the number of connections each worker process accepts. Double-check that TLS session caching works, because TLS
+handshakes can get really expensive.
+
+During a traffic peak, your web server will be able to make us of more CPU resources, while memory usage will stay comparatively low,
+so if you invest in more hardware here, invest in more and faster CPU cores.
+
+Make sure that pretix' static files (such as CSS and JavaScript assets) as well as user-uploaded media files (event logos, etc)
+are served directly by your web server and your web server caches them in-memory (nginx does it by default) and sets useful
+headers for client-side caching. As an additional performance improvement, you can turn of access logging for these types of files.
+If you want, you can even farm out serving static files to a different web server entirely and :ref:`configure pretix to reference
+them from a different URL <config-urls>`.
+
+.. tip::
+
+   If you expect *really high traffic* for your very popular event, you might want to do some rate limiting on this layer, or,
+   if you want to ensure a fair and robust first-come-first-served experience and prefer letting users wait over showing them
+   errors, consider a queuing solution. We're happy to provide you with such systems, just get in touch at sales@pretix.eu.
+
+pretix-web
+""""""""""
+
+The ``pretix-web`` process does not carry any internal state can be easily started on as many machines as you like, and you can
+use the load balancing features of your frontend web server to redirect to all of them.
+
+You can adjust the number of processes in the ``gunicorn`` command line, and we recommend choosing roughly two times the number
+of CPU cores available. Under load, the memory consumption of ``pretix-web`` will stay comparatively constant, while the CPU usage
+will increase a lot. Therefore, if you can add more or faster CPU cores, you will be able to serve more users.
+
+pretix-worker
+"""""""""""""
+
+The ``pretix-worker`` process performs all operations that are not directly executed in the request-response-cycle of ``pretix-web``.
+Just like ``pretix-web`` you can easily start up as many instances as you want on different machines to share the work. As long as they
+all talk to the same redis server, they will all receive tasks from ``pretix-web``, work on them and post their result back.
+You can configure the number of threads that run tasks in parallel through the ``--concurrency`` command line option of ``celery``.
+
+Just like ``pretix-web``, this process is mostly heavy on CPU, disk IO and network IO, although memory peaks can occur e.g. during the
+generation of large PDF files, so we recommend having some reserves here.
+
+``pretix-worker`` performs a variety of tasks which are of different importance.
+Some of them are mission-critical and need to be run quickly even during high load (such as
+creating a cart or an order), others are irrelevant and can easily run later (such as
+distributing tickets on the waiting list). You can fine-tune the capacity you assign to each
+of these tasks by running ``pretix-worker`` processes that only work on a specific **queue**.
+For example, you could have three servers dedicated only to process order creations and one
+server dedicated only to sending emails. This allows you to set priorities and also protects
+you from e.g. a slow email server lowering your ticket throughput.
+
+You can do so by specifying one or more queues on the ``celery`` command line of this process, such as ``celery -A pretix.celery_app worker -Q notifications,mail``. Currently,
+the following queues exist:
+
+* ``checkout`` -- This queue handles everything related to carts and orders and thereby everything required to process a sale. This includes adding and deleting items from carts as well as creating and canceling orders.
+
+* ``mail`` -- This queue handles sending of outgoing emails.
+
+* ``notifications`` -- This queue handles the processing of any outgoing notifications, such as email notifications to admin users (except for the actual sending) or API notifications to registered webhooks.
+
+* ``background`` -- This queue handles tasks that are expected to take long or have no human waiting for their result immediately, such as refreshing caches, re-generating CSS files, assigning tickets on the waiting list or parsing bank data files.
+
+* ``default`` -- This queue handles everything else with "medium" or unassigned priority, most prominently the generation of files for tickets, invoices, badges, admin exports, etc.
+
+Media files
+"""""""""""
+
+Both ``pretix-web``, ``pretix-worker`` and in some cases your webserver need to work with
+media files. Media files are all files generated *at runtime* by the software. This can
+include files uploaded by the event organizers, such as the event logo, files uploaded by
+ticket buyers (if you use such features) or files generated by the software, such as
+ticket files, invoice PDFs, data exports or customized CSS files.
+
+Those files are by default stored to the ``media/`` sub-folder of the data directory given
+in the ``pretix.cfg`` configuration file. Inside that ``media/`` folder, you will find a
+``pub/`` folder containing the subset of files that should be publicly accessible through
+the web server. Everything else only needs to be accessible by ``pretix-web`` and
+``pretix-worker`` themselves.
+
+If you distribute ``pretix-web`` or ``pretix-worker`` across more than one machine, you
+**must** make sure that they all have access to a shared storage to read and write these
+files, otherwise you **will** run into errors with the user interface.
+
+The easiest solution for this is probably to store them on a NFS server that you mount
+on each of the other servers.
+
+Since we use Django's file storage mechanism internally, you can in theory also use a object-storage solution like Amazon S3, Ceph, or Minio to store these files, although we currently do not expose this through pretix' configuration file and this would require you to ship your own variant of ``pretix/settings.py`` and reference it through the ``DJANGO_SETTINGS_MODULE`` environment variable.
+
+At pretix.eu, we use a custom-built `object storage cluster`_.
+
+SQL database
+""""""""""""
+
+One of the most critical parts of the whole setup is the SQL database -- and certainly the
+hardest to scale. Tuning relational databases is an art form, and while there's lots of
+material on it on the internet, there's not a single recipe that you can apply to every case.
+
+As a general rule of thumb, the more resources you can give your databases, the better.
+Most databases will happily use all CPU cores available, but only use memory up to an amount
+you configure, so make sure to set this memory usage as high as you can afford. Having more
+memory available allows your database to make more use of caching, which is usually good.
+
+Scaling your database to multiple machines needs to be treated with great caution. It's a
+good to have a replica of your database for availability reasons. In case your primary
+database server fails, you can easily switch over to the replica and continue working.
+
+However, using database replicas for performance gains is much more complicated. When using
+replicated database systems, you are always trading in consistency or availability to get
+additional performance and the consequences of this can be subtle and it is important
+that you have a deep understanding of the semantics of your replication mechanism.
+
+.. warning::
+
+   Using an off-the-shelf database proxy solution that redirects read queries to your
+   replicas and write queries to your primary database **will lead to very nasty bugs.**
+
+   As an example, if you buy a ticket, pretix first needs to calculate how many tickets
+   are left to sell. If this calculation is done on a database replica that lags behind
+   even for fractions of a second, the decision to allow selling the ticket will be made
+   on out-of-data data and you can end up with more tickets sold than configured. Similarly,
+   you could imagine situations leading to double payments etc.
+
+If you do have a replica, you *can* tell pretix about it :ref:`in your configuration <config-replica>`.
+This way, pretix can offload complex read-only queries to the replica when it is safe to do so.
+As of pretix 2.7, this is mainly used for search queries in the backend and for rendering the
+product list and event lists in the frontend, but we plan on expanding this in the future.
+
+Therefore, for now our clear recommendation is: Try to scale your database vertically and put
+it on the most powerful machine you have available.
+
+redis
+"""""
+
+While redis is a very important part that glues together some of the components, it isn't used
+heavily and can usually handle a fairly large pretix installation easily on a single modern
+CPU core.
+Having some memory available is good in case of e.g. lots of tasks queuing up during a traffic peak, but we wouldn't expect ever needing more than a gigabyte of it.
+
+Feel free to set up a redis cluster for availability – but you won't need it for performance in a long time.
+
+The limitations
+---------------
+
+Up to a certain point, pretix scales really well. However, there are a few things that we consider
+even more important than scalability, and those are correctness and reliability. We want you to be
+able to trust that pretix will not sell more tickets than you intended or run into similar error
+cases.
+
+Combined with pretix' flexibility and complexity, especially around vouchers and quotas, this creates
+some hard issues. In many cases, we need to fall back to event-global locking for some actions which
+are likely to run with high concurrency and cause harm.
+
+For every event, only one of these locking actions can be run at the same time. Examples for this are
+adding products limited by a quota to a cart, adding items to a cart using a voucher or placing an order
+consisting of cart positions that don't have a valid reservation for much longer. In these cases, it is
+currently not realistically possible to exceed selling **approx. 500 orders per minute per event**, even
+if you add more hardware.
+If you have an unlimited number of tickets, we can apply fewer locking and we've reached **approx.
+1500 orders per minute per event** in benchmarks, although even more should be possible.
+
+We're working to reduce the number of cases in which this is relevant and thereby improve the possible
+throughput. If you want to use pretix for an event with 10,000+ tickets that are likely to be sold out
+within minutes, please get in touch to discuss possible solutions. We'll work something out for you!

+Device authentication
+=====================
+
+Initializing a new device
+-------------------------
+
+Users can create new devices in the "Device" section of their organizer settings. When creating
+a new device, users can specify a list of events the device is allowed to access. After a new
+device is created, users will be presented initialization instructions, consisting of an URL
+and an initialization token. They will also be shown as a QR code with the following contents::
+
+   {"handshake_version": 1, "url": "https://pretix.eu", "token": "kpp4jn8g2ynzonp6"}
+
+Your application should be able to scan a QR code of this type, or allow to enter the URL and the
+initialization token manually. The handshake version is not used for manual initialization. When a
+QR code is scanned with a higher handshake version than you support, you should reject the request
+and prompt the user to update the client application.
+
+After your application received the token, you need to call the initialization endpoint to obtain
+a proper API token. At this point, you need to identify the name and version of your application,
+as well as the type of underlying hardware. Example:
+
+.. sourcecode:: http
+
+   POST /api/v1/device/initialize HTTP/1.1
+   Host: pretix.eu
+   Content-Type: application/json
+
+   {
+       "token": "kpp4jn8g2ynzonp6",
+       "hardware_brand": "Samsung",
+       "hardware_model": "Galaxy S",
+       "software_brand": "pretixdroid",
+       "software_version": "4.0.0"
+   }
+
+Every initialization token can only be used once. On success, you will receive a response containing
+information on your device as well as your API token:
+
+.. sourcecode:: http
+
+   HTTP/1.1 200 OK
+   Content-Type: application/json
+
+   {
+       "organizer": "foo",
+       "device_id": 5,
+       "unique_serial": "HHZ9LW9JWP390VFZ",
+       "api_token": "1kcsh572fonm3hawalrncam4l1gktr2rzx25a22l8g9hx108o9oi0rztpcvwnfnd",
+       "name": "Bar",
+       "gate": {
+           "id": 3,
+           "name": "South entrance"
+       }
+   }
+
+Please make sure that you store this ``api_token`` value. We also recommend storing your device ID, your assigned
+``unique_serial``, and the ``organizer`` you have access to, but that's up to you. ``gate`` might be ``null``.
+
+In case of an error, the response will look like this:
+
+.. sourcecode:: http
+
+   HTTP/1.1 400 Bad Request
+   Content-Type: application/json
+
+   {"token":["This initialization token has already been used."]}
+
+
+Performing API requests
+-----------------------
+
+You need to include the API token with every request to pretix' API in the ``Authorization`` header
+like the following:
+
+.. sourcecode:: http
+   :emphasize-lines: 3
+
+   GET /api/v1/organizers/ HTTP/1.1
+   Host: pretix.eu
+   Authorization: Device 1kcsh572fonm3hawalrncam4l1gktr2rzx25a22l8g9hx108o9oi0rztpcvwnfnd
+
+Updating the software version
+-----------------------------
+
+If your application is updated, we ask you to tell the server about the new version in use. You can do this at the
+following endpoint:
+
+.. sourcecode:: http
+
+   POST /api/v1/device/update HTTP/1.1
+   Host: pretix.eu
+   Content-Type: application/json
+   Authorization: Device 1kcsh572fonm3hawalrncam4l1gktr2rzx25a22l8g9hx108o9oi0rztpcvwnfnd
+
+   {
+       "hardware_brand": "Samsung",
+       "hardware_model": "Galaxy S",
+       "software_brand": "pretixdroid",
+       "software_version": "4.1.0"
+   }
+
+You will receive a response equivalent to the response of your initialization request.
+
+Creating a new API key
+----------------------
+
+If you think your API key might have leaked or just want to be extra cautious, the API allows you to create a new key.
+The old API key will be invalid immediately. A request for a new key looks like this:
+
+.. sourcecode:: http
+
+   POST /api/v1/device/roll HTTP/1.1
+   Host: pretix.eu
+   Authorization: Device 1kcsh572fonm3hawalrncam4l1gktr2rzx25a22l8g9hx108o9oi0rztpcvwnfnd
+
+The response will look like the response to the initialization request.
+
+Removing a device
+-----------------
+
+If you want implement a way to to deprovision a device in your software, you can call the ``revoke`` endpoint to
+invalidate your API key. There is no way to reverse this operation.
+
+.. sourcecode:: http
+
+   POST /api/v1/device/revoke HTTP/1.1
+   Host: pretix.eu
+   Authorization: Device 1kcsh572fonm3hawalrncam4l1gktr2rzx25a22l8g9hx108o9oi0rztpcvwnfnd
+
+This can also be done by the user through the web interface.
+
+Permissions & security profiles
+-------------------------------
+
+Device authentication is currently hardcoded to grant the following permissions:
+
+* View event meta data and products etc.
+* View orders
+* Change orders
+* Manage gift cards
+
+Devices cannot change events or products and cannot access vouchers.
+
+Additionally, when creating a device through the user interface or API, a user can specify a "security profile" for
+the device. These include an allow list of specific API calls that may be made by the device. pretix ships with security
+policies for official pretix apps like pretixSCAN and pretixPOS.
+
+Removing a device
+-----------------
+
+If you want implement a way to to deprovision a device in your software, you can call the ``revoke`` endpoint to
+invalidate your API key. There is no way to reverse this operation.
+
+.. sourcecode:: http
+

+
+This can also be done by the user through the web interface.
+
+Event selection
+---------------
+
+In most cases, your application should allow the user to select the event and check-in list they work with manually
+from a list. However, in some cases it is required to automatically configure the device for the correct event, for
+example in a kiosk-like situation where nobody is operating the device. In this case, the app can query the server
+for a suggestion which event should be used. You can also submit the configuration that is currently in use via
+query parameters:
+
+.. sourcecode:: http
+
+   GET /api/v1/device/eventselection?current_event=democon&current_subevent=42&current_checkinlist=542 HTTP/1.1
+   Host: pretix.eu
+   Authorization: Device 1kcsh572fonm3hawalrncam4l1gktr2rzx25a22l8g9hx108o9oi0rztpcvwnfnd
+
+You can get three response codes:
+
+* ``304`` The server things you already selected a good event
+* ``404`` The server has not found a suggestion for you
+* ``200`` The server suggests a new event (body see below)
+
+.. sourcecode:: http
+
+   HTTP/1.1 200 OK
+   Content-Type: application/json
+
+   {
+      "event": "democon",

 Authentication
 --------------
 
-If you're building an application for end users, we strongly recommend that you use our
-:ref:`OAuth-based authentication progress <rest-oauth>`. However, for simpler needs, you
-can also go with static API tokens that you can create on a per-team basis (see below).
+To access the API, you need to present valid authentication credentials. pretix currently
+supports the following authorization schemes:
 
-You need to include the API token with every request to pretix' API in the ``Authorization`` header
-like the following:

-.. note:: The API currently also supports authentication via browser sessions, i.e. the
-          same way that you authenticate with pretix when using the browser interface.
-          Using this type of authentication is *not* officially supported for use by
-          third-party clients and might change or be removed at any time. We plan on
-          adding OAuth2 support in the future for user-level authentication. If you want
-          to use session authentication, be sure to comply with Django's `CSRF policies`_.

-Obtaining an API token
-----------------------
-
-To authenticate your API requests, you need to obtain an API token. You can create a
-token in the pretix web interface on the level of organizer teams. Create a new team
-or choose an existing team that has the level of permissions the token should have and
-create a new token using the form below the list of team members:

-You can enter a description for the token to distinguish from other tokens later on.
-Once you click "Add", you will be provided with an API token in the success message.
-Copy this token, as you won't be able to retrieve it again.

+Idempotency
+-----------
+
+Our API supports an idempotency mechanism to make sure you can safely retry operations without accidentally performing
+them twice. This is useful if an API call experiences interruptions in transit, e.g. due to a network failure, and you
+do not know if it completed successfully.
+
+To perform an idempotent request, add a ``X-Idempotency-Key`` header with a random string value (we recommend a version
+4 UUID) to your request. If we see a second request with the same ``X-Idempotency-Key`` and the same ``Authorization``
+and ``Cookie`` headers, we will not perform the action for a second time but return the exact same response instead.
+
+Please note that this also goes for most error responses. For example, if we returned you a ``403 Permission Denied``
+error and you retry with the same ``X-Idempotency-Key``, you will get the same error again, even if you were granted
+permission in the meantime! This includes internal server errors on our side that might have been fixed in the meantime.
+
+There are only three exceptions to the rule:
+
+* Responses with status code ``409 Conflict`` are not cached. If you send the request again, it will be executed as a
+  new request, since these responses are intended to be retried.
+
+* Rate-limited responses with status code ``429 Too Many Requests`` are not cached and you can safely retry them.
+
+* Responses with status code ``503 Service Unavailable`` are not cached and you can safely retry them.
+
+If you send a request with an ``X-Idempotency-Key`` header that we have seen before but that has not yet received a
+response, you will receive a response with status code ``409 Conflict`` and are asked to retry after five seconds.
+
+We store idempotency keys for 24 hours, so you should never retry a request after a longer time period.
+
+All ``POST``, ``PUT``, ``PATCH``, or ``DELETE`` api calls support idempotency keys. Adding an idempotency key to a
+``GET``, ``HEAD``, or ``OPTIONS`` request has no effect.

+Creating an external checkout process
+=====================================
+
+Occasionally, we get asked whether it is possible to just use pretix' powerful backend as a ticketing engine but use
+a fully-customized checkout process that only communicates via the API. This is possible, but with a few limitations.
+If you go down this route, you will miss out on many of pretix features and safeguards, as well as the added flexibility
+by most of pretix' plugins. We strongly recommend to talk this through with us before you decide this is the way to go.
+
+However, this is really useful if you need to tightly integrate pretix into existing web applications that e.g. control
+the pricing of your products in a way that cannot be mapped to pretix' product structures.
+
+Creating orders
+---------------
+
+After letting your user select the products to  buy in your application, you should create a new order object inside
+pretix. Below, you can see an example of such an order, but most fields are optional and there are some more features
+supported. Read :ref:`rest-orders-create` to learn more about this endpoint.
+
+Please note that this endpoint assumes trustworthy input for the most part. By default, the endpoint checks that
+you do not exceed any quotas, do not sell any seats twice, or do not use any redeemed vouchers. However, it will not
+complain about violation of any other availability constraints, such as violation of time frames or minimum/maximum
+amounts of either your product or event. Bundled products will not be added in automatically and fees will not be
+calculated automatically.
+
+.. sourcecode:: http
+
+    POST /api/v1/organizers/democon/events/3vjrh/orders/ HTTP/1.1

+          "subevent": null
+        }
+      ],
+      "fees": []
+    }
+
+You will be returned a full order object that you can inspect, store, or use to build emails or confirmation pages for
+the user. If you don't want to do that yourself, it will also contain the URL to our confirmation page in the ``url``
+attribute. If you pass the ``"send_mail": true`` option, pretix will also send order confirmations for you.
+
+Handling payments yourself
+--------------------------
+
+If you want to handle payments in your application, you can either just create the orders with status "paid" or you can
+create them in "pending" state (the default) and later confirm the payment. We strongly advise to use the payment
+provider ``"manual"`` in this case to avoid interference with payment code with pretix.
+
+However, it is often unfeasible to implement the payment process yourself, and it also requires you to give up a
+lot of pretix functionality, such as automatic refunds. Therefore, it is also possible to utilize pretix' native
+payment process even in this case:
+
+Using pretix payment providers
+------------------------------
+
+If you passed a ``payment_provider`` during order creation above, pretix will have created a payment object with state
+``created`` that you can see in the returned order object. This payment object will have an attribute ``payment_url``
+that you can use to let the user pay. For example, you could link or redirect to this page.
+
+If you want the user to return to your application after the payment is complete, you can pass a query parameter
+``return_url``. To prepare your event for this, open your event in the pretix backend and go to "Settings", then
+"Plugins". Enable the plugin "Redirection from order page". Then, go to the new page "Settings", then "Redirection".
+Enter the base URL of your web application. This will allow you to redirect to pages under this base URL later on.
+For example, if you want users to be redirected to ``https://example.org/order/return?tx_id=1234``, you could now
+either enter ``https://example.org`` or ``https://example.org/order/``.
+
+The user will be redirected back to your page instead of pretix' order confirmation page after the payment,
+**regardless of whether it was successful or not**. Make sure you use our API to check if the payment actually
+worked! Your final URL could look like this::
+
+    https://test.pretix.eu/democon/3vjrh/order/NSLEZ/ujbrnsjzbq4dzhck/pay/123/?return_url=https%3A%2F%2Fexample.org%2Forder%2Freturn%3Ftx_id%3D1234
+
+You can also embed this page in an ``<iframe>`` instead. Note, however, that this causes problems with some payment
+methods such as PayPal which do not allow being opened in an iframe. pretix can partly work around these issues by
+opening a new window, but will only to so if you also append an ``iframe=1`` parameter to the URL::
+
+    https://test.pretix.eu/democon/3vjrh/order/NSLEZ/ujbrnsjzbq4dzhck/pay/123/?return_url=https%3A%2F%2Fexample.org%2Forder%2Freturn%3Ftx_id%3D1234&iframe=1
+
+If you did **not** pass a payment method since you want us to ask the user which payment method they want to use, you
+need to construct the URL from the ``url`` attribute of the order and the sub-path ``pay/change```. For example, you
+would end up with the following URL::
+
+    https://test.pretix.eu/democon/3vjrh/order/NSLEZ/ujbrnsjzbq4dzhck/pay/change
+
+Of course, you can also use the ``iframe`` and ``return_url`` parameters here.
+
+Optional: Cart reservations
+---------------------------
+
+Creating orders is an atomic operation: The order is either created as a whole or not at all. However, pretix'
+built-in checkout automatically reserves tickets in a user's cart for a configurable amount of time to ensure users
+will actually get their tickets once they started entering all their details. If you want a similar behavior in your
+application, you need to create :ref:`rest-carts` through the API.
+
+When creating your order, you can pass a ``consume_carts`` parameter with the cart ID(s) of your user. This way, the
+quota reserved by the cart will be credited towards the order and the carts will be destroyed if (and only if) the
+order creation succeeds.
+
+Cart creation is currently even more limited than the order creation endpoints, as cart creation currently does not
+support vouchers or automatic price calculation. If you require these features, please get in touch with us.

+Event settings
+--------------
+
+pretix events have lots and lots of parameters of different types that are stored in a key-value store on our system.
+Since many of these settings depend on each other in complex ways, we can not give direct access to all of these
+settings through the API. However, we do expose many of the simple and useful flags through the API.
+
+Please note that the available settings flags change between pretix versions and also between events, depending on the
+installed plugins, and we do not give a guarantee on backwards-compatibility like with other parts of the API.
+Therefore, we're also not including a list of the options here, but instead recommend to look at the endpoint output
+to see available options. The ``explain=true`` flag enables a verbose mode that provides you with human-readable
+information about the properties.
+
+.. note:: Please note that this is not a complete representation of all event settings. You will find more settings
+          in the web interface.
+
+.. warning:: This API is intended for advanced users. Even though we take care to validate your input, you will be
+             able to break your event using this API by creating situations of conflicting settings. Please take care.
+
+.. versionchanged:: 3.6
+
+   Initial support for settings has been added to the API.

+
+       Settings can be stored at different levels in pretix. If a value is not set on event level, a default setting

+       will no longer be inherited from the higher levels. Therefore, we recommend you to send only settings that you
+       explicitly want to set on event level. To unset a settings, pass ``null``.

+Item bundles
+============
+
+Resource description
+--------------------
+
+With bundles, you can specify products that are included within other products. There are two premier use cases of this:
+
+* Package discounts. For example, you could offer a discounted package that includes three tickets but can only be
+  bought as a whole. With a bundle including three times the usual product, the package will automatically pull three
+  sub-items into the cart, making sure of correct quota calculation and issuance of the correct number of tickets.
+
+* Tax splitting. For example, if your conference ticket includes a part that is subject to different taxation and that
+  you need to put on the invoice separately. When you putting a "designated price" on a bundled sub-item, pretix will
+  use that price to show a split taxation.
+
+The bundles resource contains the following public fields:

+Obtaining an API token
+----------------------
+
+To authenticate your API requests with Tokens, you need to obtain a team-level API token.
+You can create a token in the pretix web interface on the level of organizer teams. Create
+a new team or choose an existing team that has the level of permissions the token should
+have and create a new token using the form below the list of team members:

+Webhooks
+========
+
+pretix can send webhook calls to notify your application of any changes that happen inside pretix. This is especially
+useful for everything triggered by an actual user, such as a new ticket sale or the arrival of a payment.
+
+You can register any number of webhook URLs that pretix will notify any time one of the supported events occurs inside
+your organizer account. A great example use case of webhooks would be to add the buyer to your mailing list every time
+a new order comes in.
+
+Configuring webhooks
+--------------------
+
+You can find the list of your active webhooks in the "Webhook" section of your organizer account:
+
+.. thumbnail:: ../screens/organizer/webhook_list.png
+   :align: center
+   :class: screenshot
+
+Click "Create webhook" if you want to add a new URL. You will then be able to enter the URL pretix shall call for
+notifications. You need to select any number of notification types that you want to receive and you can optionally
+filter the events you want to receive notifications for.
+
+.. thumbnail:: ../screens/organizer/webhook_edit.png
+   :align: center
+   :class: screenshot
+
+You can also configure webhooks :ref:`through the API itself <rest-webhooks>`.
+
+Receiving webhooks
+------------------
+
+Creating a webhook endpoint on your server is no different from creating any other page on your website. If your
+website is written in PHP, you might just create a new ``.php`` file on your server; if you use a web framework like
+Symfony or Django, you would just create a new route with the desired URL.
+
+We will call your URL with a HTTP ``POST`` request with a ``JSON`` body. In PHP, you can parse this like this::
+
+    $input = @file_get_contents('php://input');
+    $event_json = json_decode($input);
+    // Do something with $event_json
+
+In Django, you would create a view like this::
+
+    def my_webhook_view(request):
+      event_json = json.loads(request.body)
+      # Do something with event_json
+      return HttpResponse(status=200)
+
+More samples for the language of your choice are easy to find online.
+
+The exact body of the request varies by notification type, but for the main types included with pretix core, such as
+those related to changes of an order, it will look like this::
+
+    {
+      "notification_id": 123455,
+      "organizer": "acmecorp",
+      "event": "democon",
+      "code": "ABC23",
+      "action": "pretix.event.order.placed"
+    }
+
+Notifications regarding a check-in will contain more details like ``orderposition_id``
+and ``checkin_list``.
+
+.. warning:: You should not trust data supplied to your webhook, but only use it as a trigger to fetch updated data.
+             Anyone could send data there if they guess the correct URL and you won't be able to tell. Therefore, we
+             only include the minimum amount of data necessary for you to fetch the changed objects from our
+             :ref:`rest-api` in an authenticated way.
+
+.. warning:: In very rare cases, you could receive the same webhook notification twice. We try to avoid it, but we
+             prefer it over missing a notification.
+
+If you want to further prevent others from accessing your webhook URL, you can also use `Basic authentication`_ and
+supply the URL to us in the format of ``https://username:password@domain.com/path/``.
+We recommend that you use HTTPS for your webhook URL and might require it in the future. If HTTPS is used, we require
+that a valid certificate is in use.
+
+.. note:: If you use a web framework that makes use of automatic CSRF protection, this protection might prevent us
+          from calling your webhook URL. In this case, we recommend that you turn of CSRF protection selectively
+          for that route. In Django, you can do this by putting the ``@csrf_exempt`` decorator on your view. In
+          Rails, you can pass an ``except`` parameter to ``protect_from_forgery``.
+
+
+Responding to a webhook
+-----------------------
+
+If you successfully received a webhook call, your endpoint should return a HTTP status code between ``200`` and ``299``.
+If any other status code is returned, we will assume you did not receive the call. This does mean that any redirection
+or ``304 Not Modified`` response will be treated as a failure. pretix will not follow any ``301`` or ``302`` redirect
+headers and pretix will ignore all other information in your response headers or body.
+
+If we do not receive a status code in the range of ``200`` and ``299``, pretix will retry to deliver for up to three
+days with an exponential back off. Therefore, we recommend that you implement your endpoint in a way where calling it
+multiple times for the same event due to a perceived error does not do any harm.
+
+There is only one exception: If status code ``410 Gone`` is returned, we will assume the
+endpoint does not exist any more and automatically disable the webhook.
+
+.. note:: If you use a self-hosted version of pretix (i.e. not our SaaS offering at pretix.eu) and you did not
+          configure a background task queue, failed webhooks will not be retried.
+
+Debugging webhooks
+------------------
+
+If you want to debug your webhooks, you can view a log of all sent notifications and the responses of your server for
+30 days right next to your configuration.

+Pluggable authentication backends
+=================================
+
+Plugins can supply additional authentication backends. This is mainly useful in self-hosted installations
+and allows you to use company-wide login mechanisms such as LDAP or OAuth for accessing pretix' backend.
+
+Every authentication backend contains an implementation of the interface defined in ``pretix.base.auth.BaseAuthBackend``
+(see below). Note that pretix authentication backends work differently than plain Django authentication backends.
+Basically, three pre-defined flows are supported:
+
+* Authentication mechanisms that rely on a **set of input parameters**, e.g. a username and a password. These can be
+  implemented by supplying the ``login_form_fields`` property and a ``form_authenticate`` method.
+
+* Authentication mechanisms that rely on **external sessions**, e.g. a cookie or a proxy HTTP header. These can be
+  implemented by supplying a ``request_authenticate`` method.
+
+* Authentication mechanisms that rely on **redirection**, e.g. to an OAuth provider. These can be implemented by
+  supplying a ``authentication_url`` method and implementing a custom return view.
+
+Authentication backends are *not* collected through a signal. Instead, they must explicitly be set through the
+``auth_backends`` directive in the ``pretix.cfg`` :ref:`configuration file <config>`.
+
+In each of these methods (``form_authenticate``, ``request_authenticate`` or your custom view) you are supposed to
+either get an existing :py:class:`pretix.base.models.User` object from the database or create a new one. There are a
+few rules you need to follow:
+
+* You **MUST** only return users with the ``auth_backend`` attribute set to the ``identifier`` value of your backend.
+
+* You **MUST** create new users with the ``auth_backend`` attribute set to the ``identifier`` value of your backend.
+
+* Every user object **MUST** have an email address. Email addresses are globally unique. If the email address is
+  already registered to a user who signs in through a different backend, you **SHOULD** refuse the login.
+
+The backend interface
+---------------------
+
+.. class:: pretix.base.auth.BaseAuthBackend
+
+   The central object of each backend is the subclass of ``BaseAuthBackend``.

+
+Logging users in
+----------------
+
+If you return a user from ``form_authenticate`` or ``request_authenticate``, the system will handle everything else
+for you correctly. However, if you use a redirection method and build a custom view to verify the login, we strongly
+recommend that you use the following utility method to correctly set session values and enforce two-factor
+authentication (if activated):

+Extending the order import process
+==================================
+
+It's possible through the backend to import orders into pretix, for example from a legacy ticketing system. If your
+plugins defines additional data structures around orders, it might be useful to make it possible to import them as well.
+
+Import process
+--------------
+
+Here's a short description of pretix' import process to show you where the system will need to interact with your plugin.
+You can find more detailed descriptions of the attributes and methods further below.
+
+1. The user uploads a CSV file. The system tries to parse the CSV file and understand its column headers.
+
+2. A preview of the file is shown to the user and the user is asked to assign the various different input parameters to
+   columns of the file or static values. For example, the user either needs to manually select a product or specify a
+   column that contains a product. For this purpose, a select field is rendered for every possible input column,
+   allowing the user to choose between a default/empty value (defined by your ``default_value``/``default_label``)
+   attributes, the columns of the uploaded file, or a static value (defined by your ``static_choices`` method).
+
+3. The user submits its assignment and the system uses the ``resolve`` method of all columns to get the raw value for
+   all columns.
+
+4. The system uses the ``clean`` method of all columns to verify that all input fields are valid and transformed to the
+   correct data type.
+
+5. The system prepares internal model objects (``Order`` etc) and uses the ``assign`` method of all columns to assign
+   these objects with actual values.
+
+6. The system saves all of these model objects to the database in a database transaction. Plugins can create additional
+   objects in this stage through their ``save`` method.
+
+Column registration
+-------------------
+
+The import API does not make a lot of usage from signals, however, it
+does use a signal to get a list of all available import columns. Your plugin
+should listen for this signal and return the subclass of ``pretix.base.orderimport.ImportColumn``
+that we'll provide in this plugin:
+
+.. sourcecode:: python
+
+    from django.dispatch import receiver
+
+    from pretix.base.signals import order_import_columns
+
+
+    @receiver(order_import_columns, dispatch_uid="custom_columns")
+    def register_column(sender, **kwargs):
+        return [
+            EmailColumn(sender),
+        ]
+
+The column class API
+--------------------
+
+.. class:: pretix.base.orderimport.ImportColumn
+
+   The central object of each import extension is the subclass of ``ImportColumn``.
+
+   .. py:attribute:: ImportColumn.event
+
+      The default constructor sets this property to the event we are currently
+      working for.

+
+For example, the import column responsible for assigning email addresses looks like this:
+
+.. sourcecode:: python
+
+   class EmailColumn(ImportColumn):
+       identifier = 'email'
+       verbose_name = _('E-mail address')
+
+       def clean(self, value, previous_values):
+           if value:
+               EmailValidator()(value)
+           return value
+
+       def assign(self, value, order, position, invoice_address, **kwargs):

+Writing an e-mail placeholder plugin
+====================================
+
+An email placeholder is a dynamic value that pretix users can use in their email templates.
+
+Please read :ref:`Creating a plugin <pluginsetup>` first, if you haven't already.
+
+Placeholder registration
+------------------------
+
+The placeholder API does not make a lot of usage from signals, however, it
+does use a signal to get a list of all available email placeholders. Your plugin
+should listen for this signal and return an instance of a subclass of ``pretix.base.email.BaseMailTextPlaceholder``::
+
+    from django.dispatch import receiver
+
+    from pretix.base.signals import register_mail_placeholders
+
+
+    @receiver(register_mail_placeholders, dispatch_uid="placeholder_custom")
+    def register_mail_renderers(sender, **kwargs):
+        from .email import MyPlaceholderClass
+        return MyPlaceholder()
+
+
+Context mechanism
+-----------------
+
+Emails are sent in different "contexts" within pretix. For example, many emails are sent in the
+the context of an order, but some are not, such as the notification of a waiting list voucher.
+
+Not all placeholders make sense in every email, and placeholders usually depend some parameters
+themselves, such as the ``Order`` object. Therefore, placeholders are expected to explicitly declare
+what values they depend on and they will only be available in an email if all those dependencies are
+met. Currently, placeholders can depend on the following context parameters:
+
+* ``event``
+* ``order``
+* ``position``
+* ``waiting_list_entry``
+* ``invoice_address``
+* ``payment``
+
+There are a few more that are only to be used internally but not by plugins.
+
+The placeholder class
+---------------------
+
+.. class:: pretix.base.email.BaseMailTextPlaceholder
+
+   .. autoattribute:: identifier
+
+      This is an abstract attribute, you **must** override this!
+
+   .. autoattribute:: required_context
+
+      This is an abstract attribute, you **must** override this!

+
+      This is an abstract method, you **must** implement this!
+
+   .. automethod:: render_sample
+
+      This is an abstract method, you **must** implement this!
+
+Helper class for simple placeholders
+------------------------------------
+
+pretix ships with a helper class that makes it easy to provide placeholders based on simple
+functions::
+
+     placeholder = SimpleFunctionalMailTextPlaceholder(
+         'code', ['order'], lambda order: order.code, sample='F8VVL'
+     )

+Digital content
+===============
+
+URL interpolation and JWT authentication
+----------------------------------------
+
+In the simplest case, you can use the digital content module to point users to a specific piece of content on some
+platform after their ticket purchase, or show them an embedded video or live stream. However, the full power of the
+module can be utilized by passing additional information to the target system to automatically authenticate the user
+or pre-fill some fields with their data. For example, you could use an URL like this::
+
+    https://webinars.example.com/join?as={attendee_name}&userid={order_code}-{positionid}
+
+While this is already useful, it does not provide much security – anyone could guess a valid combination for that URL.
+Therefore, the module allows you to pass information as a `JSON Web Token`_, which isn't encrypted, but signed with a
+shared secret such that nobody can create their own tokens or modify the contents. To use a token, set up a URL like this::
+
+    https://webinars.example.com/join?with_token={token}
+
+Additionally, you will need to set a JWT secret and a token template, either through the pretix interface or through the
+API (see below). pretix currently only supports tokens signed with ``HMAC-SHA256`` (``HS256``). Your token template can contain
+whatever JSON you'd like to pass on based on the same variables, for example::
+
+    {
+        "iss": "pretix.eu",
+        "aud": "webinars.example.com",
+        "user": {
+            "id": "{order_code}-{positionid}",
+            "product": "{product_id}",
+            "variation": "{variation_id}",
+            "name": "{attendee_name}"
+        }
+    }
+
+Variables can only be used in strings inside the JSON structure.
+pretix will automatically add an ``iat`` claim with the current timestamp and an ``exp`` claim with an expiration timestamp
+based on your configuration.
