+Scheduled data exports
+======================
+
+pretix and it's plugins include a number of data exporters that allow you to bulk download various data from pretix in
+different formats. You should read :ref:`rest-exporters` first to get an understanding of the basic mechanism.
+
+Exports can be scheduled to be sent at specific times automatically, both on organizer level and event level.
+
+Scheduled export resource
+-------------------------
+
+The scheduled export contains the following public fields:

+
+Special notes on permissions
+----------------------------
+
+Permission handling for scheduled exports is more complex than for most other objects. The reason for this is that
+there are two levels of access control involved here: First, you need permission to access or change the configuration
+of the scheduled exports in the moment you are doing it. Second, you **continuously** need permission to access the
+**data** that is exported as part of the schedule. For this reason, scheduled exports always need one user account
+to be their **owner**.
+
+Therefore, scheduled exports **must** be created by an API client using :ref:`OAuth authentication <rest-oauth>`.
+It is impossible to create a scheduled export using token authentication. After the export is created, it can also be
+modified using token authentication.
+
+A user or token with the "can change settings" permission for a given organizer or event can see and change
+**all** scheduled exports created for the respective organizer or event, regardless of who created them.
+A user without this permission can only see **their own** scheduled exports.
+A token without this permission can not see scheduled exports as all.
+
+

+KulturPass
+=========
+
+.. note::
+
+    Since the KulturPass is specific to event organizers within Germany, the following page is also  only provided in
+    German. Should you require assistance with the KulturPass and do not speak this language, please feel free reach
+    out to support@pretix.eu.
+
+
+Einführung
+----------
+Der `KulturPass`_ ist ein Angebot der Bundesregierung für alle, die im laufenden Jahr ihren 18. Geburtstag feiern.
+Sie erhalten ab ihrem 18. Geburtstag ein Budget von 200 Euro, das sie für Eintrittskarten, Bücher, CDs, Platten und
+vieles andere einsetzen können. So wird Kultur vor Ort noch einfacher erlebbar. Gleichzeitig stärkt das die Nachfrage
+bei den Anbietenden.
+
+Da pretix ein Ticketing-System ist, stellen wir ausschließlich einen automatisierten Prozess für den Verkauf von
+Eintrittskarten über den KulturPass-Marktplatz bereit.
+
+
+Registrierung und Einrichtung
+-----------------------------
+Um als Unternehmen oder Kultureinrichtung Angebote auf dem KulturPass-Marktplatz anbieten zu können, ist zunächst eine
+Registerung und die Einrichtung eines "Shops" sowie der dazugehörigen Angebote notwendig.
+
+1. Registrierung
+    Registrieren Sie sich zunächst unter https://www.kulturpass.de/anbietende/layer als Anbieter. Im Zuge der
+    Registrierung beantworten Sie einige Fragen zu Ihrem Unternehmen/Ihrer Kultureinrichtung, hinterlegen Ihre
+    E-Mail-Adresse und beantworten Fragen zu Ihren Angebotsformen sowie Finanzierung Ihrer Einrichtung.
+
+2. Anlegen eines KulturPass Shops
+    Nach Ihrer Registrierung müssen Sie der Weitergabe Ihrer Daten an die technische Platform hinter dem KulturPass,
+    Mirakl, zustimmen. Hier benennen Sie auch Ihren Shop.
+
+3. Identifizierung mit ELSTER-Zertifikat
+    Als nächsten Schritt müssen Sie Ihr Unternehmen oder Ihre Einrichtung mit Hilfe eines sog. ELSTER-Zertifikates
+    identifizieren. Dieses Zertifikat nutzen Sie auch bereits jetzt schon, wenn Sie auf elektronischem Wege mit der
+    Finanzverwaltung kommunizieren.
+
+4. Ersteinrichtung in pretix
+    Hinterlegen Sie nun die ID-Nummer Ihres KulturPass Marktplatz-Shops sowie einen API-Key in den
+    `Einstellungen Ihres Veranstalterkontos`_ (Veranstalter-Konto -> Einstellungen -> KulturPass). Diese Daten müssen
+    Sie nur einmalig für alle Ihre Veranstaltungen angeben.
+
+    Im `KulturPass-Backend`_ finden Sie die benötigten Informationen indem Sie auf das Benutzer-Symbol in der oberen,
+    rechten Ecke klicken, "Profil" und dann "API Schlüssel" auswählen bzw. indem Sie auf "Einstellungen" in der
+    Navigation links und dann "Shop" auswählen.
+
+.. note::
+
+    Zu jedem Zeitpunkt kann nur ein Hintergrundsystem mit dem KulturPass-System verbunden sein. Werden
+    unterschiedliche Systeme oder gar mehrere pretix-Veranstalterkonten mit dem gleichen KulturPass-System verbunden,
+    können keine Bestellungen mehr verarbeitet werden und Angebote nicht automatisiert an den KulturPass-Marktplatz
+    übermittelt werden. Eingehende Bestellungen von Jugendlichen werden in diesem Fall automatisch abgelehnt, da diese
+    nicht eindeutig zugeordnet werden können. Ebenso überschreibt die Bereitstellung der Angebote eines Systems die
+    Angebote eines anderen Systems.
+
+    Wenn Sie mehrere Systeme haben, die den KulturPass-Marktplatz bedienen sollen, wenden Sie sich bitte an den
+    KulturPass-Support, um sich einen weiteren Shop einrichten zu lassen.
+
+5. Aktivierung der KulturPass-Erweiterungen
+    Alle Veranstaltungen, die Sie über den KulturPass anbieten möchten, benötigen die `KulturPass-Erweiterung`_.
+    Aktivieren Sie diese bitte in jeder relevanten Veranstaltung über Einstellungen -> Erweiterungen -> Tab
+    "Integrationen" -> KulturPass.
+
+6. Konfiguration der Artikel
+    Nachdem die KulturPass-Erweiterung aktiviert wurde, müssen Sie sich entscheiden, welche Produkte Sie über den
+    KulturPass-Marktplatz anbieten möchten. In der Bearbeitungs-Ansicht des jeweiligen Produktes finden Sie hierzu im
+    Tab "Zusätzliche Einstellungen" eine Checkbox "Das Produkt kann mit dem KulturPass erworben werden".
+
+.. note::
+
+    Die Eigenschaft, dass ein Produkt durch den KulturPass-Marktplatz erworben werden kann, kann für beliebig viele
+    Produkte aktiviert werden. Auf Grund der Funktionsweise des KulturPasses sollten Sie jedoch gerade bei vielen
+    Artikeln mit unterschiedlich hohen Preisen darauf achten, dass die Preisspanne nicht zu hoch ausfällt.
+
+    Aktivieren Sie die Option für drei Produkte für 1, 10 und 100 Euro, so wird Ihr Angebot im KulturPass-Marktplatz
+    für 100 Euro gelistet werden. Dies bedeutet im Umkehrschluss auch, dass das KulturPass-Guthaben eines Jugendlichen
+    auch mindestens 100 Euro betragen muss, damit er Ihr Angebot in Anspruch nehmen kann - auch wenn die betroffene
+    Person lediglich das 1 Euro-Angebot wahrnehmen möchte. Erst mit dem 100 Euro KulturPass-Einlösecode wählt die
+    kaufende Person in Ihrem pretix-Shop aus, welches Produkt erworben werden soll. Ein Restguthaben wird nach dem Kauf
+    automatisch zurückerstattet und dem KulturPass-Konto wieder gutgeschrieben.
+
+7. Konfiguration des Marktplatz-Eintrages
+    Je nach dem, ob es sich bei Ihrer Veranstaltung um eine Einzelveranstaltung oder eine Veranstaltungsreihe handelt,
+    müssen Sie die folgende Einstellung einmalig oder pro Veranstaltungstermin vornehmen.
+
+    Einzelveranstaltungen konfigurieren Sie über den Menüpunkt "KulturPass" in den Einstellungen Ihrer Veranstaltung;
+    Veranstaltungsreihen beim Anlegen oder Editieren eines jeden einzelnen Termins am Ende der Seite.
+
+    Um eine Veranstaltung oder einen Veranstaltungstermin im KulturPass-Marktplatz anzubieten, aktivieren Sie zunächst
+    die Option "Diese Veranstaltung via KulturPass anbieten". Geben Sie im folgenden die benötigten Informationen an.
+
+    Bitte beachten Sie, dass Sie bei den Angaben präzise Titel und Beschreibungen verwenden, da der KulturPass-
+    Marktplatz ausschließlich die Informationen aus diesem Bereich verwendet. Etwaige andere Informationen die Sie
+    bspw. in den "Text auf Startseite"-Felder eingeben haben, erreichen das KulturPass-System nicht.
+
+.. note::
+
+    Gerade bei Veranstaltungsreihen nutzen viele pretix-Veranstalter gerne verkürzte Termin-Namen. Ein Schwimmbad würde
+    beispielsweise Ihre Veranstaltungsreihe "Freibad Musterstadt" und die einzelnen Termine nur "Schwimmen" nennen.
+
+    Während dies im pretix-Shop in einem gemeinsamen Kontext wunderbar funktioniert, würde eine Veranstaltung mit dem
+    Titel "Schwimmen" im KulturPass-Marktplatz Informationen vermissen lassen. Wählen Sie daher für das Eingabefeld
+    "Veranstaltungstitel" in der KulturPass-Konfiguration einen sprechenden Wert.
+
+8. Übermittlung der Angebote
+    Sobald Sie Ihre ersten Veranstaltungen konfiguriert und live geschaltet haben, übermittelt pretix automatisch in
+    regelmäßigen Abständen alle von Ihnen angebotenen Veranstaltungen an das KulturPass System (Mirakl). Bitte beachten
+    Sie jedoch, dass der Import der Produkte und Angebote einige Zeit in Anspruch nehmen kann. Zum einen müssen
+    Angebote initial händisch von den Betreibern der KulturPass-Platform freigegeben werden, zum anderen muss auch eine
+    Synchronisation zwischen dem Hintergrundsystem und der KulturPass-App erfolgen. Auf die Dauer dieser Prozesse hat
+    pretix keinen Einfluss.
+
+9. Freischalten des Marktplatz-Shops
+    Nachdem pretix erstmalig Angebote an das KulturPass-System übermittelt hat, müssen Sie Ihren Shop KulturPass-Shop
+    einmalig freischalten. Loggen Sie sich hierzu in das `KulturPass-Backend`_ ein.
+
+
+Verwalten von KulturPass-Bestellungen
+-------------------------------------
+Durch die Nutzung der pretix-Integration mit dem KulturPass-System müssen Sie sich - bis auf die Kennzeichnung von
+Produkten, die per KulturPass erworben werden dürfen, sowie die Bereitstellung von Veranstaltungs-Informationen für den
+KulturPass-Marktplatz - um nichts kümmern: pretix übermittelt automatisch Ihre Veranstaltungen, wickelt die Einlösung
+der Tickets ab und führt die Abrechnung mit dem Hintergrund-System durch.
+
+Für Ihre Kunden verhält sich der KulturPass wie eine Zahlungsmethode im Bestellprozess und wird dort neben Ihren
+anderen Zahlungsmethoden mit angeboten.
+
+Die Gelder für mit dem KulturPass bezahlte Tickets erhalten Sie in Form einer Sammel-Überweisung von der Stiftung
+Digitale Chancen auf das von Ihnen beim KulturPass Onboarding angegeben Bankkonto.
+
+In Ihrem `KulturPass-Backend`_ können Sie über den Menüpunkt "Buchhaltung" Ihre bereits erfolgten und kommenden
+Auszahlungen betrachten.
+
+.. note::
+
+    Es ist von äußerster Wichtigkeit, dass Sie weder die eingehenden Bestellungen noch die Produkte und Angebote im
+    KulturPass-Backend händisch bearbeiten - auch wenn dies möglich wäre.
+
+    Bei händischen Änderungen riskieren Sie, dass die Datenbasis zwischen pretix und dem KulturPass-System divergiert
+    und es zu fehlerhaften Buchungen kommt. Wann immer möglich, sollten Sie Korrekturbuchungen und Änderungen
+    ausschließlich über pretix vornehmen.
+
+    Sollte eine händische Änderung/Korrektur notwendig werden, wenden Sie sich bitte an den pretix-Support, damit wir
+    die Auswirkungen evaluieren und vorab mit Ihnen besprechen können!
+
+Erstattungen für Stornos und Absagen können Sie wie gehabt über das pretix-Backend vornehmen. Der jeweilige Betrag wird
+dem KulturPass-Konto dann automatisch gutgeschrieben.
+
+Da nach Ausgabe eines KulturPass Einlöse-Codes dieser vom Kunden jederzeit oder vom System bei
+Nicht-(Komplett)Einlösung binnen 48 Stunden storniert werden kann, kann das im KulturPass-Backend angezeigte,
+auszuzahlende Guthaben fluktuieren. Da in der Regel Auszahlungen frühestens 48 Stunden nach der Aufgabe einer
+KulturPass-Bestellungen erfolgen, sollte Ihr Guthaben in der Regel nicht ins Negative gehen.
+
+Ablauf für Kunden
+-----------------
+Ihre Kunden erhalten - nachdem sie sich ein eigenes Konto in der KulturPass-App angelegt und sich mit ihrem
+elektronischen Personalausweis identifiziert haben - ein Guthaben von 200 Euro, welches für Leistungen aus dem
+KulturPass-Marktplatz eingelöst werden kann.
+
+Im Falle von Veranstaltungen, die per pretix verkauft werden, wählt der Kunde ein Angebot aus und erhält im folgenden
+binnen kurzer Zeit (ca. 10-20 Minuten) einen Code und einen Link, um diesen einzulösen. Der Link bringt den Kunden direkt auf die Seite der
+betreffenden pretix-Veranstaltung. Hier wird der Kunde darauf hingewiesen, für welche Produkte der Code genutzt werden
+kann.
+
+Im Bezahlschritt des Verkaufsprozesses wird dem Kunden vorgeschlagen, seinen KulturPass Einlösecode nun zu nutzen, um
+die gewünschte Leistung zu erhalten.
+
+Wurde ein Artikel gewählt, welcher günstiger als der Wert des Einlösecodes war, wird das Restguthaben automatisch auf
+das KulturPass-Konto erstattet.
+
+Wurden hingegen mehrere Artikel in den Warenkorb gelegt, so kann die Differenz mit einem anderen, regulären
+Zahlungsmittel erfolgen.
+
+Einlösecodes, die vom Kunden nicht binnen 48 Stunden eingelöst werden, werden automatisch storniert und dem
+KulturPass-Konto wieder gutgeschrieben. Dieser Mechanismus greift auch, wenn eine Veranstaltung mittlerweile
+ausverkauft ist und daher der Einlösecode nicht mehr Nutzbar ist.

+
+Some payment providers (such as Stripe) also offer Apple or Google Pay. But in order to use them, the domain of the
+payment needs to be approved first. As of right now, pretix will take care of the domain verification process for you
+automatically, when using Stripe. However, pretix can only validate the domain that is being used for your default,

+The details might vary from payment provider to payment provider, but generally speaking, it will either involve just
