+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally

+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,

+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,

+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and

+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS

+Dealing with errors
+===================
+
+If you encounter an error in pretix, please follow the following steps to debug it:
+
+* If the error message is shown on a **white page** and the last line of the error includes "nginx", the error is not with pretix
+  directly but with your nginx webserver. This might mean that pretix is not running, but it could also be something else.
+  Please first check your nginx error log. The default location is ``/var/log/nginx/error.log``.
+
+  * If it turns out pretix is not running, check the output of ``docker logs pretix`` for a docker installation and
+    ``journalctl -u pretix-web.service`` for a manual installation.
+
+* If the error message is an "**Internal Server Error**" in purple pretix design, please check pretix' log file which by default is at
+  ``/var/pretix-data/logs/pretix.log`` if you installed with docker and ``/var/pretix/data/logs/pretix.log`` otherwise. If you don't
+  know how to interpret it, open a discussion on GitHub with the relevant parts of the log file.
+
+  * If the error message includes ``/usr/bin/env: ‘node’: No such file or directory``, you forgot to install ``node.js``
+
+  * If the error message includes ``OfflineGenerationError``, you might have forgot to run the ``rebuild`` step after a pretix update
+    or plugin installation.
+
+  * If the error message mentions your database server or redis server, make sure these are running and accessible.
+
+* If pretix loads fine but certain actions (creating carts, orders, or exports, downloading tickets, sending emails) **take forever**,
+  ``pretix-worker`` is not running. Check the output of ``docker logs pretix`` for a docker installation and
+  ``journalctl -u pretix-worker.service`` for a manual installation.
+
+* If the page loads but all **styles are missing**, you probably forgot to update your nginx configuration file after an upgrade of your
+  operating system's python version.
+
+
+If you are unable to debug the issue any further, please open a **discussion** on GitHub in our `Q&A Forum`_. Do **not** open an issue
+right away, since most things turn out not to be a bug in pretix but a mistake in your server configuration. Make sure to include
+relevant log excerpts in your question.
+
+If you're a pretix Enterprise customer, you can also reach out to support@pretix.eu with your issue right away.

+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;
+
+    CREATE INDEX CONCURRENTLY pretix_addidx_event_slug

+Update notes
+============
+
+pretix receives regular feature and bugfix updates and we highly encourage you to always update to
+the latest version for maximum quality and security. Updates are announces on our `blog`_. There are
+usually 10 feature updates in a year, so you can expect a new release almost every month.
+
+Pure bugfix releases are only issued in case of very critical bugs or security vulnerabilities. In these
+case, we'll publish bugfix releases for the last three stable release branches.
+
+Compatibility to plugins and in very rare cases API clients may break. For in-depth details on the
+API changes of every version, please refer to the release notes published on our blog.
+
+Upgrade steps
+-------------
+
+For the actual upgrade, you can usually just follow the steps from the installation guide for :ref:`manual installations <manual_updates>`
+or :ref:`docker installations <docker_updates>` respectively.
+Generally, it is always strongly recommended to perform a :ref:`backup <backups>` first.
+It is possible to skip versions during updates, although we recommend not skipping over major version numbers
+(i.e. if you want to go from 2.4 to 4.4, first upgrade to 3.0, then upgrade to 4.0, then to 4.4).
+
+In addition to these standard update steps, the following list issues steps that should be taken when you upgrade
+to specific versions for pretix. If you're skipping versions, please read the instructions for every version in
+between as well.
+
+Upgrade to 3.17.0 or newer

+Understanding the life cycle of orders
+======================================
+
+When integrating pretix with other systems, it is important that you understand how orders and related objects
+such as order positions, fees, payments, refunds, and invoices work together, in order to react to their changes
+properly and map them to processes in your system.
+
+Order states
+------------
+
+Generally, an order can be in six states. For compatibility reasons, the ``status`` field only allows four values
+and the two remaining states are modeled through the ``require_approval`` field and the number of positions within
+an order. The states and their allowed changes are shown in the following graph:
+
+.. image:: /images/order_states.png
+
+
+Object types
+------------
+
+Order
+    One order represents one purchase. It's the main object you interact with and bundles all the other objects
+    together. Orders can change in many ways during their lifetime, but will never be deleted (unless ``testmode``
+    is set to ``true``).
+
+Order position
+    An order position represents one product contained in the order. Orders can usually have multiple positions.
+    There might be a parent-child relation between order positions if one position is an add-on to another position.
+    Order positions can change in many ways during their lifetime, and can also be removed or added to an order.
+
+Order fees
+    A fee represents a charge that is not related to a product. Examples include shipping fees, service fees, and
+    cancellation fees.
+    Order fees can change in many ways during their lifetime, and can also be removed or added to an order.
+
+Order payment
+    An order payment represents one payment attempt with a specific payment method and amount. An order can have
+    multiple payments attached.
+    Order payments have their own state diagram. Apart from their state and their meta information (e.g. used
+    credit card, …) they usually don't change. They may be added at any time, but will never be deleted.
+
+Order refund
+    An order payment represents one refund attempt with a specific payment method and amount. An order can have
+    multiple refunds attached.
+    Order refunds have their own state diagram. Apart from their state and their meta information (e.g. used
+    credit card, …) they usually don't change. They may be added at any time, but will never be deleted.
+
+Invoice
+    An invoice represents a legal document stating the contents of an order. While the backend technically allows
+    to update an invoice in some situations, invoices are generally considered immutable. Once they are issued,
+    they no longer change. If the order changes substantially (e.g. prices change), an invoice is canceled through
+    creation of a new invoice with the opposite amount, plus the issuance of a new invoice.
+
+Here's an example of how they all play together:

+Checking a ticket in
+--------------------
+
+.. http:post:: /api/v1/organizers/(organizer)/checkinrpc/redeem/
+
+   Tries to redeem an order position, i.e. checks the attendee in (or out). This is the recommended endpoint to use
+   if you build any kind of scanning app that performs check-ins for scanned barcodes. It is safe to use with untrusted
+   inputs in the ``secret`` field.
+
+   This endpoint supports passing multiple check-in lists to perform a multi-event scan. However, each check-in list
+   passed needs to be from a distinct event.
+
+   :<json string secret: Scanned QR code corresponding to the ``secret`` attribute of a ticket.
+   :<json array lists: List of check-in list IDs to search on. No two check-in lists may be from the same event.
+   :<json string type: Send ``"exit"`` for an exit and ``"entry"`` (default) for an entry.
+   :<json datetime datetime: Specifies the datetime of the check-in. If not supplied, the current time will be used.
+   :<json boolean force: Specifies that the check-in should succeed regardless of revoked barcode, previous check-ins or required
+                         questions that have not been filled. This is usually used to upload offline scans that already happened,
+                         because there's no point in validating them since they happened whether they are valid or not. Defaults to ``false``.
+   :<json boolean questions_supported: When this parameter is set to ``true``, handling of questions is supported. If
+                                       you do not implement question handling in your user interface, you **must**
+                                       set this to ``false``. In that case, questions will just be ignored. Defaults
+                                       to ``true``.
+   :<json boolean ignore_unpaid: Specifies that the check-in should succeed even if the order is in pending state.
+                                 Defaults to ``false`` and only works when ``include_pending`` is set on the check-in
+                                 list.
+   :<json object answers: If questions are supported/required, you may/must supply a mapping of question IDs to their
+                          respective answers. The answers should always be strings. In case of (multiple-)choice-type
+                          answers, the string should contain the (comma-separated) IDs of the selected options.
+   :<json string nonce: You can set this parameter to a unique random value to identify this check-in. If you're sending
+                        this request twice with the same nonce, the second request will also succeed but will always
+                        create only one check-in object even when the previous request was successful as well. This
+                        allows for a certain level of idempotency and enables you to re-try after a connection failure.
+   :>json string status: ``"ok"``, ``"incomplete"``, or ``"error"``
+   :>json string reason: Reason code, only set on status ``"error"``, see below for possible values.
+   :>json string reason_explanation: Human-readable explanation, only set on status ``"error"`` and reason ``"rules"``, can be null.
+   :>json object position: Copy of the matching order position (if any was found). The contents are the same as the
+                           :ref:`order-position-resource`, with the following differences: (1) The ``checkins`` value
+                           will only include check-ins for the selected list. (2) An additional boolean property
+                           ``require_attention`` will inform you whether either the order or the item have the
+                           ``checkin_attention`` flag set. (3) If ``attendee_name`` is empty, it may automatically fall
+                           back to values from a parent product or from invoice addresses.
+   :>json boolean require_attention: Whether or not the ``require_attention`` flag is set on the item or order.
+   :>json object list: Excerpt of information about the matching :ref:`check-in list <rest-checkinlists>` (if any was found),
+                       including the attributes ``id``, ``name``, ``event``, ``subevent``, and ``include_pending``.

+Performing a ticket search
+--------------------------
+
+.. http:get:: /api/v1/organizers/(organizer)/checkinrpc/search/
+
+   Returns a list of all order positions matching a given search request. The result is the same as
+   the :ref:`order-position-resource`, with the following differences:
+
+   * The ``checkins`` value will only include check-ins for the selected list.
+
+   * An additional boolean property ``require_attention`` will inform you whether either the order or the item
+     have the ``checkin_attention`` flag set.
+
+   * If ``attendee_name`` is empty, it will automatically fall back to values from a parent product or from invoice
+     addresses.
+
+   This endpoint supports passing multiple check-in lists to perform a multi-event search. However, each check-in list
+   passed needs to be from a distinct event.

 Order position endpoints
 ------------------------
 
-.. versionchanged:: 1.15
-
-   The order positions endpoint has been extended by the filter queries ``item__in``, ``variation__in``,
-   ``order__status__in``, ``subevent__in``, ``addon_to__in``, and ``search``. The search for attendee names and order
-   codes is now case-insensitive.
-
-   The ``.../redeem/`` endpoint has been added.
-
-.. versionchanged:: 2.0
-
-   The order positions endpoint has been extended by the filter queries ``voucher`` and ``voucher__code``.
-
-.. versionchanged:: 2.7
-
-   The resource now contains the new attributes ``require_attention`` and ``order__status`` and accepts the new
-   ``ignore_status`` filter. The ``attendee_name`` field is now "smart" (see below) and the redemption endpoint
-   returns ``400`` instead of ``404`` on tickets which are known but not paid.
-
-.. versionchanged:: 3.2
-
-    The ``checkins`` dict now also contains a ``auto_checked_in`` value to indicate if the check-in has been performed
-    automatically by the system.

+Resource description
+--------------------
+
+Discounts provide a way to automatically reduce the price of a cart if it matches a given set of conditions.
+Discounts are available to everyone. If you want to give a discount just to specific persons, look at
+:ref:`vouchers <rest-vouchers>` instead. If you are interested in the behind-the-scenes details of how
+discounts are calculated for a specific order, have a look at :ref:`our algorithm documentation <algorithms-pricing>`.

+
+Running an export
+-----------------
+
+Since exports often include large data sets, they might take longer than the duration of an HTTP request. Therefore,
+creating an export is a two-step process. First you need to start an export task with one of the following to API
+endpoints:
+
+.. http:post:: /api/v1/organizers/(organizer)/events/(event)/exporters/(identifier)/run/
+
+   Starts an export task. If your input parameters validate correctly, a ``202 Accepted`` status code is returned.
+   The body points you to the download URL of the result.
+
+   **Example request**:
+
+   .. sourcecode:: http
+
+      POST /api/v1/organizers/bigevents/events/sampleconf/exporters/orderlist/run/ HTTP/1.1
+      Host: pretix.eu
+      Accept: application/json, text/javascript
+      Content-Type: application/json
+
+      {
+        "_format": "xlsx"
+      }
+
+   **Example response**:
+
+   .. sourcecode:: http
+
+      HTTP/1.1 200 OK
+      Vary: Accept
+      Content-Type: application/json
+
+      {
+        "download": "https://pretix.eu/api/v1/organizers/bigevents/events/sampleconf/exporters/orderlist/download/29891ede-196f-4942-9e26-d055a36e98b8/3f279f13-c198-4137-b49b-9b360ce9fcce/"
+      }
+
+   :param organizer: The ``slug`` field of the organizer to fetch
+   :param event: The ``slug`` field of the event to fetch
+   :param identifier: The ``identifier`` field of the exporter to run
+   :statuscode 202: no error
+   :statuscode 400: Invalid input options
+   :statuscode 401: Authentication failure
+   :statuscode 403: The requested organizer/event does not exist **or** you have no permission to view this resource.
+
+.. http:post:: /api/v1/organizers/(organizer)/exporters/(identifier)/run/
+
+   The endpoint for organizer-level exports works just like event-level exports (see above).
+
+
+Downloading the result
+----------------------
+
+When starting an export, you receive a ``url`` for downloading the result. Running a ``GET`` request on that result will
+yield one of the following status codes:
+
+* ``200 OK`` – The export succeeded. The body will be your resulting file. Might be large!
+* ``409 Conflict`` – Your export is still running. The body will be JSON with the structure ``{"status": "running", "percentage": 40}``. ``percentage`` can be ``null`` if it is not known and ``status`` can be ``waiting`` before the task is actually being processed. Please retry, but wait at least one second before you do.
+* ``410 Gone`` – Running the export has failed permanently. The body will be JSON with the structure ``{"status": "failed", "message": "Error message"}``
+* ``404 Not Found`` – The export does not exist / is expired.
+
+.. warning::
+
+   Running exports puts a lot of stress on the system, we kindly ask you not to run more than two exports at the same time.

+Organizer settings
+------------------
+
+pretix organizers and 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 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 organizer 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 shops using this API by creating situations of conflicting settings. Please take care.
+
+.. versionchanged:: 3.14

+       Settings can be stored at different levels in pretix. If a value is not set on organizer 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 organizer level. To unset a settings, pass ``null``.

+Data shredders
+==============
+
+pretix and it's plugins include a number of data shredders that allow you to clear personal information from the system.
+This page shows you how to use these shredders through the API.
+
+.. versionchanged:: 4.12
+
+   This feature has been added to the API.
+

+

+
+Running an export
+-----------------
+
+Before you can delete data, you need to start a data export.
+Since exports often include large data sets, they might take longer than the duration of an HTTP request. Therefore,
+creating an export is a two-step process. First you need to start an export task with one of the following to API
+endpoints:
+
+.. http:post:: /api/v1/organizers/(organizer)/events/(event)/shredders/export/
+
+   Starts an export task. If your input parameters validate correctly, a ``202 Accepted`` status code is returned.
+   The body points you to the download URL of the result as well as the URL for the next step.
+
+   **Example request**:
+
+   .. sourcecode:: http
+
+      POST /api/v1/organizers/bigevents/events/sampleconf/shredders/export/ HTTP/1.1
+      Host: pretix.eu

+      }
+
+   :param organizer: The ``slug`` field of the organizer to fetch
+   :param event: The ``slug`` field of the event to fetch
+   :param identifier: The ``identifier`` field of the exporter to run
+   :statuscode 202: no error

+   :statuscode 401: Authentication failure
+   :statuscode 403: The requested organizer/event does not exist **or** you have no permission to view this resource.
+
+
+Downloading the result
+----------------------
+
+When starting an export, you receive a ``download`` URL for downloading the result. Running a ``GET`` request on that result will
+yield one of the following status codes:
+
+* ``200 OK`` – The export succeeded. The body will be your resulting file. Might be large!
+* ``409 Conflict`` – Your export is still running. The body will be JSON with the structure ``{"status": "running"}``. ``status`` can be ``waiting`` before the task is actually being processed. Please retry, but wait at least one second before you do.
+* ``410 Gone`` – Running the export has failed permanently. The body will be JSON with the structure ``{"status": "failed", "message": "Error message"}``
+* ``404 Not Found`` – The export does not exist / is expired / belongs to a different API key.
+
+
+Shredding the data
+------------------
+
+When starting an export, you receive a ``shred`` URL for actually shredding the data.
+You can only start the actual shredding process after the export file was generated, however you are not forced to download
+the file (we'd recommend it in most cases, though).
+The download will no longer be possible after the shredding.
+Since shredding often requires deleting large data sets, it might take longer than the duration of an HTTP request.
+Therefore, shredding again is a two-step process. First you need to start a shredder task with one of the following to API
+endpoints:
+
+.. http:post:: /api/v1/organizers/(organizer)/events/(event)/shredders/shred/(id1)/(id2)/
+
+   Starts an export task. If your input parameters validate correctly, a ``202 Accepted`` status code is returned.
+   The body points you to an URL you can use to check the status.

+
+   .. sourcecode:: http

+   :statuscode 410: Either the job has timed out or running the export has failed permanently. The body will be JSON with the structure ``{"status": "failed", "message": "Error message"}``
+
+
+Checking the result
+-------------------
+
+When starting to shred, you receive a ``status`` URL for checking for success.
+Running a ``GET`` request on that result will yield one of the following status codes:
+
+* ``200 OK`` – The shredding succeeded.
+* ``409 Conflict`` – Shredding is still running. The body will be JSON with the structure ``{"status": "running"}``. ``status`` can be ``waiting`` before the task is actually being processed. Please retry, but wait at least one second before you do.
+* ``410 Gone`` – We no longer know about this process, probably the process was started more than an hour ago. Might also occur after successful operations on small pretix installations without asynchronous task handling.
+* ``417 Expectation Failed`` – Running the export has failed permanently. The body will be JSON with the structure ``{"status": "failed", "message": "Error message"}``

+Check-in algorithms
+===================

+When a ticket is scanned at the entrance or exit of an event, we follow a series of steps to determine whether
+the check-in is allowed or not. To understand some of the terms in the following diagrams, you should also check
+out the documentation of the :ref:`ticket redemption API endpoint <rest-checkin-redeem>`.
+
+Server-side
+-----------
+
+The following diagram shows the series of checks executed on the server when a ticket is redeemed through the API.
+Some simplifications have been made, for example the deduplication mechanism based on the ``nonce`` parameter
+to prevent re-uploads of the same scan is not shown.
+
+.. image:: /images/checkin_online.png
+
+Client-side
+-----------
+
+The process of verifying tickets offline is a little different. There are two different approaches,
+depending on whether we have information about all tickets in the local database. The following diagram shows
+the algorithm as currently implemented in recent versions of `libpretixsync`_.

+Algorithms
+==========
+
+The business logic inside pretix is full of complex algorithms making decisions based on all the hundreds of settings
+and input parameters available. Some of them are documented here as graphs, either because fully understanding them is very important

+ticket scanning apps and we want to ensure the implementations are as similar as possible to avoid confusion.

+Pricing algorithms
+==================
+
+With pretix being an e-commerce application, one of its core tasks is to determine the price of a purchase. With the
+complexity allowed by our range of features, this is not a trivial task and there are many edge cases that need to be
+clearly defined. The most challenging part about this is that there are many situations in which a price might change
+while the user is going through the checkout process and we're learning more information about them or their purchase.
+For example, prices change when
+
+* The cart expires and the listed prices changed in the meantime
+* The user adds an invoice address that triggers a change in taxation
+* The user chooses a custom price for an add-on product and adjusts the price later on
+* The user adds a voucher to their cart
+* An automatic discount is applied
+
+For the purposes of this page, we're making a distinction between "naive prices" (which are just a plain number like 23.00), and
+"taxed prices" (which are a combination of a net price, a tax rate, and a gross price, like 19.33 + 19% = 23.00).
+
+Computation of listed prices
+----------------------------
+
+When showing a list of products, e.g. on the event front page, we always need to show a price. This price is what we
+call the "listed price" later on.
+
+To compute the listed price, we first use the ``default_price`` attribute of the ``Item`` that is being shown.
+If we are showing an ``ItemVariation`` and that variation has a ``default_price`` set on itself, the variation's price
+takes precedence and replaces the item's price.
+If we're in an event series and there exists a ``SubEventItem`` or ``SubEventItemVariation`` with a price set, the
+subevent's price configuration takes precedence over both the item as well as the variation and replaces the listed price.
+
+Listed prices are naive prices. Before we actually show them to the user, we need to check if ``TaxRule.price_includes_tax``
+is set to determine if we need to add tax or subtract tax to get to the taxed price. We then consider the event's
+``display_net_prices`` setting to figure out which way to present the taxed price in the interface.
+
+Guarantees on listed prices
+---------------------------
+
+One goal of all further logic is that if a user sees a listed price, they are guaranteed to get the product at that
+price as long as they complete their purchase within the cart expiration time frame. For example, if the cart expiration
+time is set to 30 minutes and someone puts a item listed at €23 in their cart at 4pm, they can still complete checkout
+at €23 until 4.30pm, even if the organizer decides to raise the price to €25 at 4.10pm. If they complete checkout after
+4.30pm, their cart will be adjusted to the new price and the user will see a warning that the price has changed.
+
+Computation of cart prices
+--------------------------
+
+Input
+"""""
+
+To ensure the guarantee mentioned above, even in the light of all possible dynamic changes, the ``listed_price``
+is explicitly stored in the ``CartPosition`` model after the item has been added to the cart.
+
+If ``Item.free_price`` is set, the user is allowed to voluntarily increase the price. In this case, the user's input
+is stored as ``custom_price_input`` without much further validation for use further down below in the process.
+If ``display_net_prices`` is set, the user's input is also considered to be a net price and ``custom_price_input_is_net``
+is stored for the cart position. In any other case, the user's input is considered to be a gross price based on the tax
+rules' default tax rate.
+
+The computation of prices in the cart always starts from the ``listed_price``. The ``list_price`` is only computed
+when adding the product to the cart or when extending the cart's lifetime after it expired. All other steps such as
+creating an order based on the cart trust ``list_price`` without further checks.
+
+Vouchers
+""""""""
+
+As a first step, the cart is checked for any voucher that should be applied to the position. If such a voucher exists,
+it's discount (percentage or fixed) is applied to the listed price. The result of this is stored to ``price_after_voucher``.
+Since ``listed_price`` naive, ``price_after_voucher`` is naive as well. As a consequence, if you have a voucher configured
+to "set the price to €10", it depends on ``TaxRule.price_includes_tax`` again whether this is €10 including or excluding
+taxes.
+
+The ``price_after_voucher`` is only computed when adding the product to the cart or when extending the cart's
+lifetime after it expired. It is also checked again when the order is created, since the available discount might have
+changed due to the voucher's budget being (almost) exhausted.
+
+Line price
+""""""""""
+
+The next step computes the final price of this position if it is the only position in the cart. This happens in "reverse
+order", i.e. before the computation can be performed for a cart position, the step needs to be performed on all of its
+bundled positions. The sum of ``price_after_voucher`` of all bundled positions is now called ``bundled_sum``.
+
+First, the value from ``price_after_voucher`` will be processed by the applicable ``TaxRule.tax()`` (which is complex
+in itself but is not documented here in detail at the moment).
+
+If ``custom_price_input`` is not set, ``bundled_sum`` will be subtracted from the gross price and the net price is
+adjusted accordingly. The result is stored as ``tax_rate`` and ``line_price_gross`` in the cart position.
+
+If ``custom_price_input`` is set, the value will be compared to either the gross or the net value of the ``tax()``
+result, depending on ``custom_price_input_is_net``. If the comparison yields that the custom price is higher, ``tax()``
+will be called again . Then, ``bundled_sum`` will be subtracted from the gross price and the result is stored like
+above.
+
+The computation of ``line_price_gross`` from ``price_after_voucher``, ``custom_price_input``, and tax settings
+is repeated after every change of anything in the cart or after every change of the invoice address.
+
+Discounts
+---------
+
+After ``line_price_gross`` has been computed for all positions, the discount engine will run to apply any automatic
+discounts. Organizers can add rules for automatic discounts in the pretix backend. These rules are ordered and
+will be applied in order. Every cart position can only be "used" by one discount rule. "Used" can either mean that
+the price of the position was actually discounted, but it can also mean that the position was required to enable
+a discount for a different position, e.g. in case of a "buy 3 for the price of 2" offer.
+
+The algorithm for applying an individual discount rule first starts with eliminating all products that do not match
+the rule based on its product scope. Then, the algorithm is handled differently for different configurations.
+
+Case 1: Discount based on minimum value without respect to subevents
+""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""
+
+* Check whether the gross sum of all positions is at least ``condition_min_value``, otherwise abort.
+
+* Reduce the price of all positions by ``benefit_discount_matching_percent``.

+
+* Check whether the number of all positions is at least ``condition_min_count``, otherwise abort.
+
+* If ``benefit_only_apply_to_cheapest_n_maches`` is set,
+
+    * Sort all positions by price.
+    * Reduce the price of the first ``n_positions // condition_min_count * benefit_only_apply_to_cheapest_n_matches`` positions by ``benefit_discount_matching_percent``.
+    * Mark the first ``n_positions // condition_min_count * condition_min_count`` as "used" to hide them from further rules.

+
+* Else,
+
+    * Reduce the price of all positions by ``benefit_discount_matching_percent``.
+    * Mark all positions as "used" to hide them from further rules.
+
+Case 3: Discount only for products of the same subevent
+"""""""""""""""""""""""""""""""""""""""""""""""""""""""
+
+* Split the cart into groups based on the subevent.
+
+* Proceed with case 1 or 2 for every group.
+
+Case 4: Discount only for products of distinct subevents
+""""""""""""""""""""""""""""""""""""""""""""""""""""""""
+
+* Let ``subevents`` be a list of distinct subevents in the cart.
+
+* Let ``positions[subevent]`` be a list of positions for every subevent.
+
+* Let ``current_group`` be the current group and ``groups`` the list of all groups.
+
+* Repeat
+
+    * Order ``subevents`` by the length of their ``positions[subevent]`` list, starting with the longest list.
+      Do not count positions that are part of ``current_group`` already.
+
+    * Let ``candidates`` be the concatenation of all ``positions[subevent]`` lists with the same length as the
+      longest list.
+
+    * If ``candidates`` is empty, abort the repetition.
+
+    * Order ``candidates`` by their price, starting with the lowest price.
+
+    * Pick one entry from ``candidates`` and put it into ``current_group``. If ``current_group`` is shorter than
+      ``benefit_only_apply_to_cheapest_n_matches``, we pick from the start (lowest price), otherwise we pick from
+      the end (highest price)
+
+    * If ``current_group`` is now ``condition_min_count``, remove all entries from ``current_group`` from
+      ``positions[…]``, add ``current_group`` to ``groups``, and reset ``current_group`` to an empty group.

+
+Handling cookie consent
+=======================
+
+pretix includes an optional feature to handle cookie consent explicitly to comply with EU regulations.
+If your plugin sets non-essential cookies or includes a third-party service that does so, you should
+integrate with this feature.
+
+Server-side integration
+-----------------------
+
+First, you need to declare that you are using non-essential cookies by responding to the following
+signal:
+
+.. automodule:: pretix.presale.signals
+   :members: register_cookie_providers
+
+You are expected to return a list of ``CookieProvider`` objects instantiated from the following class:
+
+.. class:: pretix.presale.cookies.CookieProvider
+
+   .. py:attribute:: CookieProvider.identifier
+
+      A short and unique identifier used to distinguish this cookie provider form others (required).
+
+   .. py:attribute:: CookieProvider.provider_name
+
+      A human-readable name of the entity of feature responsible for setting the cookie (required).
+
+   .. py:attribute:: CookieProvider.usage_classes
+
+      A list of enum values from the ``pretix.presale.cookies.UsageClass`` enumeration class, such as
+      ``UsageClass.ANALYTICS``, ``UsageClass.MARKETING``, or ``UsageClass.SOCIAL`` (required).
+
+   .. py:attribute:: CookieProvider.privacy_url
+
+      A link to a privacy policy (optional).
+
+Here is an example of such a receiver:
+
+.. code-block:: python
+
+   @receiver(register_cookie_providers)
+   def recv_cookie_providers(sender, request, **kwargs):
+       return [
+           CookieProvider(
+               identifier='google_analytics',
+               provider_name='Google Analytics',
+               usage_classes=[UsageClass.ANALYTICS],
+           )
+       ]
+
+JavaScript-side integration
+---------------------------
+
+The server-side integration only causes the cookie provider to show up in the cookie dialog. You still
+need to care about actually enforcing the consent state.
+
+You can access the consent state through the ``window.pretix.cookie_consent`` variable. Whenever the
+value changes, a ``pretix:cookie-consent:change`` event is fired on the ``document`` object.
+
+The variable will generally have one of the following states:
+
+.. rst-class:: rest-resource-table
+
+================================================================ =====================================================
+State                                                            Interpretation
+================================================================ =====================================================
+``pretix === undefined || pretix.cookie_consent === undefined``  Your JavaScript has loaded before the cookie consent
+                                                                 script. Wait for the event to be fired, then try again,
+                                                                 do not yet set a cookie.
+``pretix.cookie_consent === null``                               The cookie consent mechanism has not been enabled. This
+                                                                 usually means that you can set cookies however you like.
+``pretix.cookie_consent[identifier] === undefined``              The cookie consent mechanism is loaded, but has no data
+                                                                 on your cookie yet, wait for the event to be fired, do not
+                                                                 yet set a cookie.
+``pretix.cookie_consent[identifier] === true``                   The user has consented to your cookie.
+``pretix.cookie_consent[identifier] === false``                  The user has actively rejected your cookie.
+================================================================ =====================================================
+
+If you are integrating e.g. a tracking provider with native cookie consent support such
+as Facebook's Pixel, you can integrate it like this:
+
+.. code-block:: javascript
+
+     var consent = (window.pretix || {}).cookie_consent;
+     if (consent !== null && !(consent || {}).facebook) {
+         fbq('consent', 'revoke');
+     }
+     fbq('init', ...);
+     document.addEventListener('pretix:cookie-consent:change', function (e) {
+         fbq('consent', (e.detail || {}).facebook ? 'grant' : 'revoke');
+     })
+
+If you have a JavaScript function that you only want to load if consent for a specific ``identifier``
+is given, you can wrap it like this:
+
+.. code-block:: javascript
+
+     var consent_identifier = "youridentifier";
+     var consent = (window.pretix || {}).cookie_consent;
+     if (consent === null || (consent || {})[consent_identifier] === true) {
+         // Cookie consent tool is either disabled or consent is given
+         addScriptElement(src);
+         return;
+     }
+
+     // Either cookie consent tool has not loaded yet or consent is not given
+     document.addEventListener('pretix:cookie-consent:change', function onChange(e) {
+         var consent = e.detail || {};
+         if (consent === null || consent[consent_identifier] === true) {
+             addScriptElement(src);
+             document.removeEventListener('pretix:cookie-consent:change', onChange);
