+
+Migrating from MySQL/MariaDB to PostgreSQL
+==========================================
+
+Our recommended database for all production installations is PostgreSQL. Support for MySQL/MariaDB has been removed
+in newer pretix releases.
+
+In order to follow this guide, your pretix installation needs to be a version that fully supports MySQL/MariaDB. If you
+already upgraded to pretix 5.0 or later, downgrade back to the last 4.x release using ``pip``.
+
+.. note:: We have tested this guide carefully, but we can't assume any liability for its correctness. The data loss
+          risk should be low as long as pretix is not running while you do the migration. If you are a pretix Enterprise
+          customer, feel free to reach out in advance if you want us to support you along the way.
+
+Update database schema
+----------------------
+
+Before you start, make sure your database schema is up to date::
+
+    # sudo -u pretix -s
+    $ source /var/pretix/venv/bin/activate
+    (venv)$ python -m pretix migrate
+
+Install PostgreSQL
+------------------
+
+Now, install and set up a PostgreSQL server. For a local installation on Debian or Ubuntu, use::
+
+    # apt install postgresql
+
+Having the database server installed, we still need a database and a database user. We can create these with any kind
+of database managing tool or directly on our database's shell. Please make sure that UTF8 is used as encoding for the
+best compatibility. You can check this with the following command::
+
+    # sudo -u postgres psql -c 'SHOW SERVER_ENCODING'
+
+Without Docker
+""""""""""""""
+
+For our standard manual installation, create the database and user like this::
+
+    # sudo -u postgres createuser pretix
+    # sudo -u postgres createdb -O pretix pretix
+
+With Docker
+"""""""""""
+
+For our standard docker installation, create the database and user like this::
+
+    # sudo -u postgres createuser -P pretix
+    # sudo -u postgres createdb -O pretix pretix
+
+Make sure that your database listens on the network. If PostgreSQL on the same same host as docker, but not inside a docker container, we recommend that you listen on the Docker interface by changing the following line in ``/etc/postgresql/<version>/main/postgresql.conf``::
+
+    listen_addresses = 'localhost,172.17.0.1'
+
+You also need to add a new line to ``/etc/postgresql/<version>/main/pg_hba.conf`` to allow network connections to this user and database::
+
+    host    pretix          pretix          172.17.0.1/16           md5
+
+Restart PostgreSQL after you changed these files::
+
+    # systemctl restart postgresql
+
+If you have a firewall running, you should also make sure that port 5432 is reachable from the ``172.17.0.1/16`` subnet.
+
+Of course, instead of all this you can also run a PostgreSQL docker container and link it to the pretix container.
+
+Stop pretix
+-----------
+
+To prevent any more changes to your data, stop pretix from running::
+
+    # systemctl stop pretix-web pretix-worker
+
+Change configuration
+--------------------
+
+Change the database configuration in your ``/etc/pretix/pretix.cfg`` file::
+
+    [database]
+    backend=postgresql
+    name=pretix
+    user=pretix
+    password=  ; only required for docker or remote database, can be kept empty for local auth
+    host=      ; set to 172.17.0.1 in docker setup, keep empty for local auth
+
+
+Create database schema
+-----------------------
+
+To create the schema in your new PostgreSQL database, use the following commands::
+
+    # sudo -u pretix -s
+    $ source /var/pretix/venv/bin/activate
+    (venv)$ python -m pretix migrate
+
+
+Migrate your data
+-----------------
+
+Install ``pgloader``::
+
+    # apt install pgloader
+
+.. note::
+
+   If you are using Ubuntu 20.04, the ``pgloader`` version from the repositories seems to be incompatible with PostgreSQL
+   12+. You can install ``pgloader`` from the `PostgreSQL repositories`_ instead.
+   See also `this discussion <https://github.com/pretix/pretix/issues/3090>`_.
+
+Create a new file ``/tmp/pretix.load``, replacing the MySQL and PostgreSQL connection strings with the correct user names, passwords, and/or database names::
+
+    LOAD DATABASE
+        FROM mysql://pretix:password@localhost/pretix  -- replace with mysql://username:password@hostname/dbname
+        INTO postgresql:///pretix                      -- replace with dbname
+
+    WITH data only, include no drop, truncate, disable triggers,
+         create no indexes, drop indexes, reset sequences
+
+    ALTER SCHEMA 'pretix' RENAME TO 'public'           -- replace pretix with the name of the MySQL database
+
+    ALTER TABLE NAMES MATCHING ~/.*/
+        SET SCHEMA 'public'
+
+    SET timezone TO '+00:00'
+
+    SET PostgreSQL PARAMETERS
+         maintenance_work_mem to '128MB',
+         work_mem to '12MB';
+
+Then, run::
+
+    # sudo -u postgres pgloader /tmp/pretix.load
+
+The output should end with a table summarizing the results for every table. You can ignore warnings about type casts
+and missing constraints.
+
+Afterwards, delete the file again::
+
+    # rm -rf /tmp/pretix.load
+
+Start pretix
+------------
+
+Now, restart pretix. Maybe stop your MySQL server as a verification step that you are no longer using it::
+
+    # systemctl stop mariadb
+    # systemctl start pretix-web pretix-worker
+
+And you're done! After you've verified everything has been copied correctly, you can delete the old MySQL database.
+
+.. note:: Don't forget to update your backup process to back up your PostgreSQL database instead of your MySQL database now.
+
+Troubleshooting
+---------------
+
+Peer authentication failed
+""""""""""""""""""""""""""
+
+Sometimes you might see an error message like this::
+
+    django.db.utils.OperationalError: connection to server on socket "/var/run/postgresql/.s.PGSQL.5432" failed: FATAL:  Peer authentication failed for user "pretix"
+
+It is important to understand that PostgreSQL by default offers two types of authentication:
+
+- **Peer authentication**, which works automatically based on the Linux user you are working as. This requires that
+  the connection is made through a local socket (empty ``host=`` in ``pretix.cfg``) and the name of the PostgreSQL user
+  and the Linux user are identical.
+
+  - Typically, you might run into this error if you accidentally execute ``python -m pretix`` commands as root instead
+    of the ``pretix`` user.
+
+- **Password authentication**, which requires a username and password and works over network connections. To force
+  password authentication instead of peer authentication, set ``host=127.0.0.1`` in ``pretix.cfg``.
+
+  - You can alter the password on a PostgreSQL shell using the command ``ALTER USER pretix WITH PASSWORD '***';``.
+    When creating a user with the ``createuser`` command, pass option ``-P`` to set a new password.
+
+  - Even with password authentication, PostgreSQL by default only allows local connections. To allow remote connections,
+    you need to adjust both the ``listen_address`` configuration parameter as well as the ``pg_hba.conf`` file (see above
+    for an example with the docker networking setup).
+
+Database error: relation does not exist
+"""""""""""""""""""""""""""""""""""""""
+
+If you see an error like this::
+
+    2023-04-17T19:20:47.744023Z ERROR Database error 42P01: relation "public.pretix_foobar" does not exist
+    QUERY: ALTER TABLE public.pretix_foobar DROP CONSTRAINT IF EXISTS pretix_foobar_order_id_57e2cb41_fk_pretixbas CASCADE;
+    2023-04-17T19:20:47.744023Z FATAL Failed to create the schema, see above.
+
+The reason is most likely that in the past, you installed a pretix plugin that you no longer have installed. However,
+the database still contains tables of that plugin. If you want to keep the data, reinstall the plugin and re-run the
+``migrate`` step from above. If you want to get rid of the data, manually drop the table mentioned in the error message
+from your MySQL database::
+
+    # mysql -u root pretix
+    mysql> DROP TABLE pretix_foobar;
+
+Then, retry. You might see a new error message with a new table, which you can handle the same way.
+
+Cleaning out a failed attempt
+"""""""""""""""""""""""""""""
+
+You might want to clean your PostgreSQL database before you try again after an error. You can do so like this::
+
+    # sudo -u postgres psql pretix
+    pretix=# DROP SCHEMA public CASCADE;
+    pretix=# CREATE SCHEMA public;
+    pretix=# ALTER SCHEMA public OWNER TO pretix;
+
+``pgloader`` crashes with heap exhaustion error
+"""""""""""""""""""""""""""""""""""""""""""""""
+
+On some larger databases, we've seen ``pgloader`` crash with error messages similar to this::
+
+    Heap exhausted during garbage collection: 16 bytes available, 48 requested.
+
+Or this::
+
+    2021-01-04T21:31:17.367000Z ERROR A SB-KERNEL::HEAP-EXHAUSTED-ERROR condition without bindings for heap statistics.  (If
+    you did not expect to see this message, please report it.
+    2021-01-04T21:31:17.382000Z ERROR The value
+      NIL
+    is not of type
+      NUMBER
+    when binding SB-KERNEL::X
+
+The ``pgloader`` version distributed for Debian and Ubuntu is compiled with the ``SBCL`` compiler. If compiled with
+``CCL``, these bugs go away. Unfortunately, it is pretty hard to compile ``pgloader`` manually with ``CCL``. If you
+run into this, we therefore recommend using the docker container provided by the ``pgloader`` maintainers::
+
+    sudo docker run --rm -v /tmp:/tmp --network host -it dimitri/pgloader:ccl.latest pgloader /tmp/pretix.load
+
+As peer authentication is not available from inside the container, this requires you to use password-based authentication
+in PostgreSQL (see above).

+Mifare Ultralight AES
+=====================
+
+We offer an implementation that provides a higher security level than the UID-based approach and uses the `Mifare Ultralight AES`_ chip sold by NXP.
+We believe the security model of this approach is adequate to the situation where this will usually be used and we'll outline known risks below.
+
+If you want to dive deeper into the properties of the Mifare Ultralight AES chip, we recommend reading the `data sheet`_.
+
+Random UIDs
+-----------
+
+Mifare Ultralight AES supports a feature that returns a randomized UID every time a non-authenticated user tries to
+read the UID. This has a strong privacy benefit, since no unauthorized entity can use the NFC chips to track users.
+On the other hand, this reduces interoperability of the system. For example, this prevents you from using the same NFC
+chips for a different purpose where you only need the UID. This will also prevent your guests from reading their UID
+themselves with their phones, which might be useful e.g. in debugging situations.
+
+Since there's no one-size-fits-all choice here, you can enable or disable this feature in the pretix organizer
+settings. If you change it, the change will apply to all newly encoded chips after the change.
+
+Key management
+--------------
+
+For every organizer, the server will generate create a "key set", which consists of a publicly known ID (random 32-bit integer) and two 16-byte keys ("diversification key" and "UID key").
+
+Using our :ref:`Device authentication mechanism <rest-deviceauth>`, an authorized device can submit a locally generated RSA public key to the server.
+This key can no longer changed on the server once it is set, thus protecting against the attack scenario of a leaked device API token.
+
+The server will then include key sets in the response to ``/api/v1/device/info``, encrypted with the device's RSA key.
+This includes all key sets generated for the organizer the device belongs to, as well as all keys of organizers that have granted sufficient access to this organizer.
+
+The device will decrypt the key sets using its RSA key and store the key sets locally.
+
+.. warning:: The device **will** have access to the raw key sets. Therefore, there is a risk of leaked master keys if an
+             authorized device is stolen or abused. Our implementation in pretixPOS attempts to make this very hard on
+             modern, non-rooted Android devices by keeping them encrypted with the RSA key and only storing the RSA key
+             in the hardware-backed keystore of the device. A sufficiently motivated attacker, however, will likely still
+             be able to extract the keys from a stolen device.
+
+Encoding a chip
+---------------
+
+When a new chip is encoded, the following steps will be taken:
+
+- The UID of the chip is retrieved.
+
+- A chip-specific key is generated using the mechanism documented in `AN10922`_ using the "diversification key" from the
+  organizer's key set as the CMAC key and the diversification input concatenated in the from of ``0x01 + UID + APPID + SYSTEMID``
+  with the following values:
+
+  - The UID of the chip as ``UID``
+
+  - ``"eu.pretix"`` (``0x65 0x75 0x2e 0x70 0x72 0x65 0x74 0x69 0x78``) as ``APPID``
+
+  - The ``public_id`` from the organizer's key set as a 4-byte big-endian value as ``SYSTEMID``
+
+- The chip-specific key is written to the chip as the "data protection key" (config pages 0x30 to 0x33)
+
+- The UID key from the organizer's key set is written to the chip as the "UID retrieval key" (config pages 0x34 to 0x37)
+
+- The config page 0x29 is set like this:
+
+  - ``RID_ACT`` (random UID) to ``1`` or ``0`` based on the organizer's configuration
+  - ``SEC_MSG_ACT`` (secure messaging) to ``1``
+  - ``AUTH0`` (first page that needs authentication) to 0x04 (first non-UID page)
+
+- The config page 0x2A is set like this:
+
+  - ``PROT`` to ``0`` (only write access restricted, not read access)
+  - ``AUTHLIM`` to ``256`` (maximum number of wrong authentications before "self-desctruction")
+  - Everything else to its default value (no lock bits are set)
+
+- The ``public_id`` of the key set will be written to page 0x04 as a big-endian value
+
+- The UID of the chip will be registered as a reusable medium on the server.
+
+.. warning:: During encoding, the chip-specific key and the UID key are transmitted in plain text over the air. The
+             security model therefore relies on the encoding of chips being performed in a trusted physical environment
+             to prevent a nearby attacker from sniffing the keys with a strong antenna.
+
+.. note:: If an attacker tries to authenticate with the chip 256 times using the wrong key, the chip will become
+          unusable. A chip may also become unusable if it is detached from the reader in the middle of the encoding
+          process (even though we've tried to implement it in a way that makes this unlikely).
+
+Usage
+-----
+
+When a chip is presented to the NFC reader, the following steps will be taken:
+
+- Command ``GET_VERSION`` is used to determine if it is a Mifare Ultralight AES chip (if not, abort).
+
+- Page 0x04 is read. If it is all zeroes, the chip is considered un-encoded (abort). If it contains a value that
+  corresponds to the ``public_id`` of a known key set, this key set is used for all further operations. If it contains
+  a different value, we consider this chip to belong to a different organizer or not to a pretix system at all (abort).
+
+- An authentication with the chip using the UID key is performed.
+
+- The UID of the chip will be read.
+
+- The chip-specific key will be derived using the mechanism described above in the encoding step.
+
+- An authentication with the chip using the chip-specific key is performed. If this is fully successful, this step
+  proves that the chip knows the same chip-specific key as we do and is therefore an authentic chip encoded by us and
+  we can trust its UID value.
+
+- The UID is transmitted to the server to fetch the correct medium.
+
+During these steps, the keys are never transmitted in plain text and can thus not be sniffed by a nearby attacker
+with a strong antenna.

+UID-based
+=========
+
+With UID-based NFC, only the unique ID (UID) of the NFC chip is used for identification purposes.
+This can be used with virtually all NFC chips that provide compatibility with the NFC reader in use, typically at least all chips that comply with ISO/IEC 14443-3A.
+
+We make only one restriction: The UID may not start with ``08``, since that usually signifies a randomized UID that changes on every read (which would not be very useful).
+

+ePayBL
+======
+
+.. note::
+
+    Since ePayBL is only available to german federal, provincial and communal entities, the following page is also
+    only provided in german. Should you require assistance with ePayBL and do not speak this language, please feel free

+
+
+Einführung
+----------
+
+.. note::
+
+    Sollten Sie lediglich schnell entscheiden wollen, welcher Kontierungsmodus in den Einstellungen des pretix
+    ePayBL-plugins gewählt werden soll, so springen Sie direkt zur Sektion :ref:`Kontierungsmodus`.
+
+
+`ePayBL`_ - das ePayment-System von Bund und Länder - ist das am weitesten verbreitete Zahlungssystem für Bundes-, Länder-
+sowie kommunale Aufgabenträger. Während es nur wie eines von vielen anderen Zahlungssystemen scheint, so bietet es
+seinen Nutzern besondere Vorteile, wie die automatische Erfassung von Zahlungsbelegen, dem Übertragen von Buchungen in
+Haushaltskassen/-systeme sowie die automatische Erfassung von Kontierungen und Steuermerkmalen.
+
+Rein technisch gesehen ist ePayBL hierbei nicht ein eigenständiger Zahlungsdienstleister sondern nur ein eine Komponente
+im komplexen System, dass die Zahlungsabwicklung für Kommunen und Behörden ist.
+
+Im folgenden der schematische Aufbau einer Umgebung, in welcher ePayBL zum Einsatz kommt:
+
+.. figure:: img/epaybl_flowchart.png
+   :class: screenshot
+
+   Quelle: Integrationshandbuch ePayBL-Konnektor, DResearch Digital Media Systems GmbH
+
+
+In diesem Schaubild stellt pretix, bzw. die von Ihnen als Veranstalter angelegten Ticketshops, das Fachverfahren dar.
+
+ePayBL stellt das Bindeglied zwischen den Fachverfahren, Haushaltssystemen und dem eigentlichen Zahlungsdienstleister,
+dem sog. ZV-Provider dar. Dieser ZV-Provider ist die Stelle, welche die eigentlichen Kundengelder einzieht und an den
+Händler auszahlt. Das Gros der Zahlungsdienstleister unterstützt pretix hierbei auch direkt; sprich: Sollten Sie die
+Anbindung an Ihre Haushaltssysteme nicht benötigen, kann eine direkte Anbindung in der Regel ebenso - und dies bei meist
+vermindertem Aufwand - vorgenommen werden.
+
+In der Vergangenheit zeigte sich jedoch schnell, dass nicht jeder IT-Dienstleister immer sofort die neueste Version von
+ePayBL seinen Nutzern angeboten hat. Die Gründe hierfür sind mannigfaltig: Von fest vorgegebenen Update-Zyklen bis hin
+zu Systeme mit speziellen Anpassungen, kann leider nicht davon ausgegangen werden, dass alle ePayBL-Systeme exakt gleich
+ansprechbar sind - auch wenn es sich dabei eigentlich um einen standardisierten Dienst handelt.
+
+Aus diesem Grund gibt es mit dem ePayBL-Konnektor eine weitere Abstraktionsschicht welche optional zwischen den
+Fachverfahren und dem ePayBL-Server sitzt. Dieser Konnektor wird so gepflegt, dass er zum einen eine dauerhaft
+gleichartige Schnittstelle den Fachverfahren bietet aber gleichzeitig auch mit jeder Version des ePayBL-Servers
+kommunizieren kann - egal wie neu oder alt, wie regulär oder angepasst diese ist.
+
+Im Grunde müsste daher eigentlich immer gesagt werden, dass pretix eine Anbindung an den ePayBL-Konnektor bietet; nicht
+an "ePayBL" oder den "ePayBL-Server". Diese Unterscheidung kann bei der Ersteinrichtung und Anforderung von Zugangsdaten
+von Relevanz sein. Da in der Praxis jedoch beide Begriffe gleichbedeutend genutzt werden, wird im Folgenden auch nur von
+einer ePayBL-Anbindung die Rede sein - auch wenn explizit der Konnektor gemeint ist.
+
+
+.. _`Kontierungsmodus`:
+
+Kontierungsmodus
+----------------
+
+ePayBL ist ein Produkt, welches für die Abwicklung von Online-Zahlungsvorgängen in der Verwaltung geschaffen wurde. Ein
+Umfeld, in dem klar definiert ist, was ein Kunde gerade bezahlt und wohin das Geld genau fließt. Diese Annahmen lassen
+sich in einem Ticketshop wie pretix jedoch nur teilweise genauso abbilden.
+
+Die ePayBL-Integration für pretix bietet daher zwei unterschiedliche Modi an, wie Buchungen erfasst und an ePayBL und
+damit auch an die dahinterliegenden Haushaltssysteme gemeldet werden können.
+
+Kontierung pro Position/Artikel
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Dieser Modus versucht den klassischen, behördentypischen ePayBL-Zahlungsvorgang abzubilden: Jede einzelne Position, die
+ein Kunde in den Warenkorb legt, wird auch genauso 1:1 an ePayBL und die Hintergrundsysteme übermittelt.
+
+Hierbei muss zwingend auch für jede Position ein Kennzeichen für Haushaltsstelle und Objektnummer, sowie optional ein
+Kontierungsobjekt (``HREF``; bspw. ``stsl=Steuerschlüssel;psp=gsb:Geschäftsbereich,auft:Innenauftrag,kst:Kostenstelle;``
+) übermittelt werden.
+
+Diese Daten sind vom Veranstalter entsprechend für jeden in der Veranstaltung angelegten Artikel innerhalb des Tabs
+"Zusätzliche Einstellungen" der Produkteinstellungen zu hinterlegen.
+
+Während diese Einstellung eine größtmögliche Menge an Kontierungsdaten überträgt und auch ein separates Verbuchen von
+Leistungen auf unterschiedliche Haushaltsstellen erlaubt, so hat diese Option auch einen großen Nachteil: Der Kunde kann
+nur eine Zahlung für seine Bestellung leisten.
+
+Während sich dies nicht nach einem großen Problem anhört, so kann dies beim Kunden zu Frust führen. pretix bietet die
+Option an, dass ein Veranstalter eine Bestellung jederzeit verändern kann: Ändern von Preisen von Positionen in einer
+aufgegebenen Bestellung, Zubuchen und Entfernen von Bestellpositionen, etc. Hat der Kunde seine ursprüngliche Bestellung
+jedoch schon bezahlt, kann pretix nicht mehr die komplette Bestellung mit den passenden Kontierungen übertragen - es
+müsste nur ein Differenz-Abbild zwischen Ursprungsbestellung und aktueller Bestellung übertragen werden. Aber auch wenn
+eine "Nachmeldung" möglich wäre, so wäre ein konkretes Auflösen für was jetzt genau gezahlt wird, nicht mehr möglich.
+
+Daher gilt bei der Nutzung der Kontierung pro Position/Artikel: Der Kunde kann nur eine (erfolgreiche) Zahlung auf seine
+Bestellung leisten.
+
+Eine weitere Einschränkung dieses Modus ist, dass aktuell keine Gebühren-Positionen (Versandkosten, Zahlungs-, Storno-
+oder Servicegebühren) in diesem Modus übertragen werden können. Bitte wenden Sie sich an uns, wenn Sie diese
+Funktionalität benötigen.
+
+
+Kontierung pro Zahlvorgang
+^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Dieser Modus verabschiedet sich vom behördlichen "Jede Position gehört genau zu einem Haushaltskonto und muss genau
+zugeordnet werden". Stattdessen werden alle Bestellpositionen - inklusive eventuell definierter Gebühren - vermengt und
+nur als ein großer Warenkorb, genauer gesagt: eine einzige Position an ePayBL sowie die Hintergrundsysteme gemeldet.
+
+Während im "pro Postion/Artikel"-Modus jeder Artikel einzeln übermittelt wird und damit auch korrekt pro Artikel der
+jeweilige Brutto- und Nettopreis, sowie der anfallende Steuerbetrag und ein Steuerkennzeichen (mit Hilfe des optionalen
+``HREF``-Attributs) übermittelt werden, ist dies im "pro Zahlvorgang"-Modus nicht möglich.
+
+Stattdessen übermittelt pretix nur einen Betrag für den gesamten Warenkorb: Bruttopreis == Nettopreis. Der Steuerbetrag
+wird hierbei als 0 übermittelt.
+
+Die Angabe einer Haushaltsstelle und Objektnummer, sowie optional der ``HREF``-Kontierungsinformationen ist jedoch
+weiterhin notwendig - allerdings nicht mehr individuell für jeden Artikel/jede Position sondern nur für die gesamte
+Bestellung. Diese Daten sind direkt in den ePayBL-Einstellungen der Veranstaltung unter Einstellungen -> Zahlung ->
+ePayBL vorzunehmen
+
+In der Praxis bedeutet dies, dass in einem angeschlossenen Haushaltssystem nicht nachvollzogen kann, welche Positionen
+konkret erworben und bezahlt wurden - stattdessen kann nur der Fakt, dass etwas verkauft wurde erfasst werden.
+
+Je nach Aufbau und Vorgaben der Finanzbuchhaltung kann dies jedoch ausreichend sein - wenn bspw. eine Ferienfahrt
+angeboten wird und seitens der Haushaltssysteme nicht erfasst werden muss, wie viel vom Gesamtbetrag einer Bestellung
+auf die Ferienfahrt an sich, auf einen Zubringerbus und einen Satz Bettwäsche entfallen ist, sondern (vereinfacht
+gesagt) es ausreichend ist, dass "Eine Summe X für die Haushaltsstelle/Objektnummer geflossen ist".
+
+Dieser Modus der Kontierung bietet Ihnen auch als Vorteil gegenüber dem vorhergehenden an, dass die Bestellungen der
+Kunden jederzeit erweitert und verändert werden können - auch wenn die Ursprungsbestellung schon bezahlt wurde und nur
+noch eine Differenz gezahlt wird.
+
+
+Einschränkungen
+---------------
+
+Zum aktuellen Zeitpunkt erlaubt die pretix-Anbindung an ePayBL nicht das durchführen von Erstattungen von bereits
+geleisteten Zahlungen. Der Prozess hierfür unterscheidet sich von Behörde zu Behörde und muss daher händisch
+durchgeführt werden.
