+
+.. note:: On pretix Hosted, using the lead scanning feature of the exhibitors plugin can add additional costs

+App API
+-------
+
+The App API is used for communication between the pretixLEAD app and the pretix server.
+
+.. warning:: We consider this an internal API, it is not intended for external use. You may still use it, but
+             our :ref:`compatibility commitment <rest-compat>` does not apply.
+
+Authentication
+""""""""""""""
+
+Every exhibitor has an "access code", usually consisting of 8 alphanumeric uppercase characters.
+This access code is communicated to event exhibitors by the event organizers, so this is also what
+exhibitors should enter into a login screen.
+
+All API requests need to contain this access code as a header like this::
+
+    Authorization: Exhibitor ABCDE123
+
+Exhibitor profile
+"""""""""""""""""
+
+Upon login and in regular intervals after that, the API should fetch the exhibitors profile.
+This serves two purposes:
+
+* Checking if the authorization code is actually valid
+
+* Obtaining information that can be shown in the app
+
+The resource consists of the following fields:

+Submitting a lead
+"""""""""""""""""
+
+After a ticket/badge is scanned, it should immediately be submitted to the server
+so the scan is stored and information about the person can be shown in the app. The same
+code can be submitted multiple times, so it's no problem to just submit it again after the
+exhibitor set a note or a rating (0-5) inside the app.
+
+On the request, you should set the following properties:
+
+* ``code`` with the scanned barcode
+* ``notes`` with the exhibitor's notes
+* ``scanned`` with the date and time of the actual scan (not the time of the upload)
+* ``scan_type`` set to ``lead`` statically
+* ``tags`` with the list of selected tags
+* ``rating`` with the rating assigned by the exhibitor
+* ``device_name`` with a user-specified name of the device used for scanning (max. 190 characters), or ``null``
+
+If you submit ``tags`` and ``rating`` to be ``null`` and ``notes`` to be ``""``, the server
+responds with the previously saved information and will not delete that information. If you
+supply other values, the information saved on the server will be overridden.
+
+The response will also contain ``tags``, ``rating``, and ``notes``. Additionally,
+it will include ``attendee`` with a list of ``fields`` that can be shown to the
+user. Each field has an internal ``id``, a human-readable ``label``, and a ``value`` (all strings).
+
+Note that the ``fields`` array can contain any number of dynamic keys!
+Depending on the exhibitors permission and event configuration this might be empty,
+or contain lots of details. The app should dynamically show these values (read-only)
+with the labels sent by the server.
+
+The request for this looks like this:
+
+.. http:post:: /exhibitors/api/v1/leads/
+
+   **Example request:**
+
+   .. sourcecode:: http
+

+Secrets Import
+==============
+
+Usually, pretix generates ticket secrets (i.e. the QR code used for scanning) itself. You can read more about this
+process at :ref:`secret_generators`.
+
+With the "Secrets Import" plugin, you can upload your own list of secrets to be used instead. This is useful for
+integrating with third-party check-in systems.
+
+
+API Resource description
+-------------------------
+
+The secrets import plugin provides a HTTP API that allows you to create new secrets.
+
+The imported secret resource contains the following public fields:

+
+Presale SAML Authentication
+===========================
+
+The Presale SAML Authentication plugin is an advanced plugin, which most event
+organizers will not need to use. However, for the select few  who do require
+strong customer authentication that cannot be covered by the built-in customer
+account functionality, this plugin allows pretix to connect to a SAML IdP and
+perform authentication and retrieval of user information.
+
+Usage of the plugin is governed by two separate sets of settings: The plugin
+installation, the Service Provider (SP) configuration and the event
+configuration.
+
+Plugin installation and initial configuration
+---------------------------------------------
+
+.. note:: If you are a customer of our hosted `pretix.eu`_ offering, you can
+          skip this section.
+
+The plugin is installed as any other plugin in the pretix ecosystem. As a
+pretix system administrator, please follow the instructions in the the
+:ref:`Administrator documentation <admindocs>`.
+
+Once installed, you will need to assess, if you want (or need) your pretix
+instance to be a single SP for all organizers and events or if every event
+organizer has to provide their own SP.
+
+Take the example of a university which runs pretix under an pretix Enterprise
+agreement. Since they only provide ticketing services to themselves (every
+organizer is still just a different department of the same university), a
+single SP should be enough.
+
+On the other hand, a reseller such as `pretix.eu`_ who services a multitude
+of clients would not work that way. Here, every organizer is a separate
+legal entity and as such will also need to provide their own SP configuration:
+Company A will expect their SP to reflect their company - and not a generalized
+"pretix SP".
+
+Once you have decided on the mode of operation, the :ref:`Configuration file
+<config>` needs to be extended to reflect your choice.
+
+Example::
+
+    [presale-saml]
+    level=global
+
+``level``
+    ``global`` to use only a single, system-wide SP, ``organizer`` for multiple
+    SPs, configured on the organizer-level. Defaults to ``organizer``.
+
+Service Provider configuration
+------------------------------
+
+Global Level
+^^^^^^^^^^^^
+
+.. note:: If you are a customer of our hosted `pretix.eu`_ offering, you can
+          skip this section and follow the instructions on the upcoming
+          Organizer Level settings.
+
+As a user with administrative privileges, please activate them by clicking the
+`Admin Mode` button in the top right hand corner.
+
+You should now see a new menu-item titled `SAML` appear.
+
+Organizer Level
+^^^^^^^^^^^^^^^
+
+Navigate to the organizer settings in the pretix backend. In the navigation
+bar, you will find a menu-item titled `SAML` if your user has the `Can
+change organizer settings` permission.
+
+
+.. note:: If you are a customer of our hosted `pretix.eu`_ offering, the menu
+          will only appear once one of our friendly customer service agents
+          has enabled the Presale SAML Authentication plugin for at least one
+          of your events. Feel free to get in touch with us!
+
+Setting up the SP
+^^^^^^^^^^^^^^^^^
+
+No matter where your SP configuration lives, you will be greeted by a very
+long list of fields of which almost all of them will need to be filled. Please
+don't be discouraged - most of the settings don't need to be decided by yourself
+and/or are already preset with a sensible default setting.
+
+If you are not sure what setting you should choose for any of the fields, you
+should reach out to your IdP operator as they can tell you exactly what the IdP
+expects and - more importantly - supports.
+
+``IdP Metadata URL``
+    Please provide the URL where your IdP outputs its metadata. For most IdPs,
+    this URL is static and the same for all SPs. If you are a member of the
+    DFN-AAI, you can find the meta-data for the `Test-, Basic- and
+    Advanced-Federation`_ on their website. Please do talk with your local
+    IdP operator though, as you might not even need to go through the DFN-AAI
+    and might just use your institutions local IdP which will also host their
+    metadata on a different URL.
+
+    The URL needs to be publicly accessible, as saving the settings form will
+    fail if the IdP metadata cannot be retrieved. pretix will also automatically
+    refresh the IdP metadata on a regular basis.
+
+``SP Entity Id``
+    By default, we recommend that you use the system-proposed metadata-URL as
+    the Entity Id of your SP. However, if so desired or required by your IdP,
+    you can also set any other, arbitrary URL as the SP Entity Id.
+
+``SP Name / SP Decription``
+    Most IdP will display the name and description of your SP to the users
+    during authentication. The description field can be used to explain to the
+    users how their data is being used.
+
+``SP X.509 Certificate / SP X.509 Private Key``
+    Your SP needs a certificate and a private key for said certificate. Please
+    coordinate with your IdP, if you are supposed to generate these yourself or
+    if they are provided to you.
+
+``SP X.509 New Certificate``
+    As certificates have an expiry date, they need to be renewed on a regular
+    basis. In order to facilitate the rollover from the expiring to the new
+    certificate, you can provide the new certificate already before the expiration
+    of the existing one. That way, the system will automatically use the correct
+    one. Once the old certificate has expired and is not used anymore at all,
+    you can move the new certificate into the slot of the normal certificate and
+    keep the new slot empty for your next renewal process.
+
+``Requested Attributes``
+    An IdP can hold a variety of attributes of an authenticating user. While
+    your IdP will dictate which of the available attributes your SP can consume
+    in theory, you will still need to define exactly which attributes the SP
+    should request.
+
+    The notation is a JSON list of objects with 5 attributes each:
+
+      * ``attributeValue``: Can be defaulted to ``[]``.
+      * ``friendlyName``: String used in the upcoming event-level settings to
+        retrieve the attributes data.
+      * ``isRequired``: Boolean indicating whether the IdP must enforce the
+        transmission of this attribute. In most cases, ``true`` is the best
+        choice.
+      * ``name``: String of the internal, technical name of the requested
+        attribute. Often starting with ``urn:mace:dir:attribute-def:``,
+        ``urn:oid:`` or ``http://``/``https://``.
+      * ``nameFormat``: String describing the type of ``name`` that has been
+        set in the previous section. Often starting with
+        ``urn:mace:shibboleth:1.0:`` or ``urn:oasis:names:tc:SAML:2.0:``.
+
+    Your IdP can provide you with a list of available attributes. See below
+    for a sample configuration in an academic context.
+
+    Note, that you can have multiple attributes with the same ``friendlyName``
+    but different ``name``s. This is often used in systems, where the same
+    information (for example a persons name) is saved in different fields -
+    for example because one institution is returning SAML 1.0 and other
+    institutions are returning SAML 2.0 style attributes. Typically, this only
+    occurs in mix environments like the DFN-AAI with a large number of
+    participants. If you are only using your own institutions IdP and not
+    authenticating anyone outside of your realm, this should not be a common
+    sight.
+
+``Encrypt/Sign/Require ...``
+    Does what is says on the box - please inquire with your IdP for the
+    necessary settings. Most settings can be turned on as they increase security,
+    however some IdPs might stumble over some of them.
+
+``Signature / Digest Algorithm``
+    Please chose appropriate algorithms, that both pretix/your SP and the IdP
+    can communicate with. A common source of issues when connecting to a
+    Shibboleth-based IdP is the Digest Algorithm: pretix does not support
+    ``http://www.w3.org/2009/xmlenc11#rsa-oaep`` and authentication will fail
+    if the IdP enforces this.
+
+``Technical/Support Contacts``
+    Those contacts are encoded into the SPs public meta data and might be
+    displayed to users having trouble authenticating. It is recommended to
+    provide a dedicated point of contact for technical issues, as those will
+    be the ones to change the configuration for the SP.
+
+Event / Authentication configuration
+------------------------------------
+
+Basic settings
+^^^^^^^^^^^^^^
+
+Once the plugin has been enabled for a pretix event using the Plugins-menu from
+the event's settings, a new *SAML* menu item will show up.
+
+On this page, the actual authentication can be configured.
+
+``Checkout Explanation``
+    Since most users probably won't be familiar with why they have to authenticate
+    to buy a ticket, you can provide them a small blurb here. Markdown is supported.
+
+``Attribute RegEx``
+    By default, any successful authentication with the IdP will allow the user to
+    proceed with their purchase. Should the allowed audience needed to be restricted
+    further, a set of regular Expressions can be used to do this.
+
+    An Attribute RegEx of ``{}`` will allow any authenticated user to pass.
+
+    A RegEx of ``{ "affiliation": "^(employee@pretix.eu|staff@pretix.eu)$" }`` will
+    only allow user to pass which have the ``affiliation`` attribute and whose
+    attribute either matches ``employee@pretix.eu`` or ``staff@pretix.eu``.
+
+    Please make sure that the attribute you are querying is also requested from the
+    IdP in the first place - for a quick check you can have a look at the top of
+    the page where all currently configured attributes are listed.
+
+``RegEx Fail Explanation``
+    Only used in conjunction with the above Attribute RegEx. Should the user not
+    pass the restrictions imposed by the regular expression, the user is shown
+    this error-message.
+
+    If you are - for example in an university context - restricting access to
+    students only, you might want to explain here that Employees are not allowed
+    to book tickets.
+
+``Ticket Secret SAML Attribute``
+    In very specific instances, it might be desirable that the ticket-secret is
+    not the randomly one generated by pretix but rather based on one of the
+    users attributes - for example their unique ID or access card number.
+
+    To achieve this, the name of a SAML-attribute can be specified here.
+
+    It is however necessary to note, that even with this setting in use,
+    ticket-secrets need to be unique. This is why when this setting is enabled,
+    the default, pretix-generated ticket-secret is prefixed with the attributes
+    value.
+
+    Example: A users ``cardid`` attribute has the value of ``01189998819991197253``.
+    The default random ticket secret would have been
+    ``yczygpw9877akz2xwdhtdyvdqwkv7npj``. The resulting new secret will now be
+    ``01189998819991197253_yczygpw9877akz2xwdhtdyvdqwkv7npj``.
+
+    That way, the ticket secret is still unique, but when checking into an event,
+    the user can easily be searched and found using their identifier.
+
+IdP-provided E-Mail addresses, names
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+By default, pretix will only authenticate the user and not process the received
+data any further.
+
+However, there are a few exceptions to this rule.
+
+There are a few `magic` attributes that pretix will use to automatically populate
+the corresponding fields within the checkout process **and lock them out from
+user editing**.
+
+  * ``givenName`` and ``sn``: If both of those attributes are present and pretix
+    is configured to collect the users name, these attributes' values are used
+    for the given and family name respectively.
+  * ``email``: If this attribute is present, the E-Mail-address of the users will
+    be set to the one transmitted through the attributes.
+
+The latter might pose a problem, if the IdP is transmitting an ``email`` attribute
+which does contain a system-level mail address which is only used as an internal
+identifier but not as a real mailbox. In this case, please consider setting the
+``friendlyName`` of the attribute to a different value than ``email`` or removing
+this field from the list of requested attributes altogether.
+
+Saving attributes to questions
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+By setting the ``internal identifier`` of a user-defined question to the same name
+as a SAML attribute, pretix will save the value of said attribute into the question.
+
+All the same as in the above section on E-Mail addresses, those fields become
+non-editable by the user.
+
+Please be aware that some specialty question types might not be compatible with
+the SAML attributes due to specific format requirements. If in doubt (or if the
+checkout fails/the information is not properly saved), try setting the question
+type to a simple type like "Text (one line)".
+
+Notes and configuration examples

+Requesting SAML 1.0 and 2.0 attributes from an academic IdP
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+This requests the ``eduPersonPrincipalName`` (also sometimes called EPPN),
+``email``, ``givenName`` and ``sn`` both in SAML 1.0 and SAML 2.0 attributes.

-pretixdroid HTTP API
-====================
-
-The pretixdroid plugin provides a HTTP API that the `pretixdroid Android app`_
-uses to communicate with the pretix server.
-
-.. warning:: This API is **DEPRECATED** and will probably go away soon. It is used **only** to serve the pretixdroid
-             Android app. There are no backwards compatibility guarantees on this API. We will not add features that
-             are not required for the  Android App. There is a general-purpose :ref:`rest-api` that provides all
-             features that you need to check in.
-
-.. versionchanged:: 1.12
-
-   Support for check-in-time questions has been added. The new API features are fully backwards-compatible and
-   negotiated live, so clients which do not need this feature can ignore the change. For this reason, the API version
-   has not been increased and is still set to 3.
-
-.. versionchanged:: 1.13
-
-   Support for checking in unpaid tickets has been added.
-
-
-.. http:post:: /pretixdroid/api/(organizer)/(event)/redeem/
-
-   Redeems a ticket, i.e. checks the user in.
-
-   **Example request**:
-
-   .. sourcecode:: http
-
-      POST /pretixdroid/api/demoorga/democon/redeem/?key=ABCDEF HTTP/1.1
-      Host: demo.pretix.eu
-      Accept: application/json, text/javascript
-      Content-Type: application/x-www-form-urlencoded
-
-      secret=az9u4mymhqktrbupmwkvv6xmgds5dk3&questions_supported=true
-
-   You **must** set the parameter secret.
-
-   You **must** set the parameter ``questions_supported`` to ``true`` **if** you support asking questions
-   back to the app operator. You **must not** set it if you do not support this feature. In that case, questions
-   will just be ignored.
-
-   You **may** set the additional parameter ``datetime`` in the body containing an ISO8601-encoded
-   datetime of the entry attempt. If you don"t, the current date and time will be used.
-
-   You **may** set the additional parameter ``force`` to indicate that the request should be logged
-   regardless of previous check-ins for the same ticket. This might be useful if you made the entry decision offline.
-   Questions will also always be ignored in this case (i.e. supplied answers will be saved, but no error will be
-   thrown if they are missing or invalid).
-
-   You **may** set the additional parameter ``nonce`` with a globally unique random value to identify this
-   check-in. This is meant to be used to prevent duplicate check-ins when you are just retrying after a connection
-   failure.
-
-   You **may** set the additional parameter ``ignore_unpaid`` to indicate that the check-in should be performed even
-   if the order is in pending state.
-
-   If questions are supported and required, you will receive a dictionary ``questions`` containing details on the
-   particular questions to ask. To answer them, just re-send your redemption request with additional parameters of
-   the form ``answer_<question>=<answer>``, e.g. ``answer_12=24``.
-

+to output e.g. order data, which contains data from untrusted sources such as attendee names.
+

+- It makes sure strings starting with = are treated as text, not as a formula, as openpyxl will

+- It removes characters considered invalid by Excel to avoid exporter crashes.
