-Tax codes
----------
-
-For integration with external systems, such as electronic invoicing or bookkeeping systems, the tax rate itself is often
-not sufficient information. For example, there could be many different reasons why a sale has a tax rate of 0 %, but the
-external handling of the transaction depends on which reason applies. Therefore, pretix allows to supply a codified
-reason that allows us to understand what the specific legal situation is. These tax codes are modeled after a combination
-of the code lists from the European standard EN16931 and the German standard DSFinV-K.
-
-The following codes are supported:
-
-- ``S/standard`` -- Standard VAT rate in the merchant country
-- ``S/reduced`` -- Reduced VAT rate in the merchant country
-- ``S/averaged`` -- Averaged VAT rate in the merchant country (known use case: agricultural businesses in Germany)
-- ``AE`` -- Reverse charge
-- ``O`` -- Services outside of scope of tax
-- ``E`` -- Exempt from tax (no reason given)
-- ``E/<reason>`` -- Exempt from tax, where ``<reason>`` is one of the codes listed in the `VATEX code list`_ version 5.0.
-- ``Z`` -- Zero-rated goods
-- ``G`` -- Free export item, VAT not charged
-- ``K`` -- VAT exempt for EEA intra-community supply of goods and services
-- ``L`` -- Canary Islands general indirect tax
-- ``M`` -- Tax for production, services and importation in Ceuta and Melilla
-- ``B`` -- Transferred (VAT), only in Italy
-
-The code set in the ``code`` attribute of the tax rule is used by default. When ``eu_reverse_charge`` is active, the
-code is replaced by ``AE`` for reverse charge sales and by ``O`` for non-EU sales. When configuring custom rules, you
-should actively set a ``"code"`` key on each rule. Only for ``"action": "reverse"`` we automatically apply the code
-``AE``, in all other cases the default ``code`` of the tax rule is selected.

-
-   With this API call, you can instruct the system to render a set of tickets into one combined PDF file. To specify
-   which tickets to render, you need to submit a list of "parts". For every part, the following fields are supported:
-
-   * ``orderposition`` (``integer``, required): The ID of the order position to render.
-   * ``override_channel`` (``string``, optional): The sales channel ID to be used for layout selection instead of the
-     original channel of the order.
-   * ``override_layout`` (``integer``, optional): The ticket layout ID to be used instead of the auto-selected one.
-
-   If your input parameters validate correctly, a ``202 Accepted`` status code is returned.
-   The body points you to the download URL of the result. Running a ``GET`` request on that result URL 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.
-

-Basic concepts
-==============
-
-This page describes basic concepts and definition that you need to know to interact
-with our Storefront API, such as authentication, pagination and similar definitions.
-
-.. _`storefront-auth`:
-
-Authentication
---------------
-
-The storefront API requires authentication with an API key. You receive two kinds of API keys for the storefront API:
-Publishable keys and private keys. Publishable keys should be used when your website directly connects to the API.
-Private keys should be used only on server-to-server connections.
-
-Localization
-------------
-
-The storefront API will return localized and translated strings in many cases if you set an ``Accept-Language`` header.
-The selected locale will only be respected if it is active for the organizer or event in question.
-
-.. _`storefront-compat`:
-
-Compatibility
--------------
-
-.. note::
-
-   The storefront API is currently considered experimental and may change without notice.
-   Once we declare the API stable, the following compatibility policy will apply.
-
-We try to avoid any breaking changes to our API to avoid hassle on your end. If possible, we'll
-build new features in a way that keeps all pre-existing API usage unchanged. In some cases,
-this might not be possible or only possible with restrictions. In these case, any
-backwards-incompatible changes will be prominently noted in the "Changes to the REST API"
-section of our release notes. If possible, we will announce them multiple releases in advance.
-
-We treat the following types of changes as *backwards-compatible* so we ask you to make sure
-that your clients can deal with them properly:
-
-* Support of new API endpoints
-* Support of new HTTP methods for a given API endpoint
-* Support of new query parameters for a given API endpoint
-* New fields contained in API responses
-* New possible values of enumeration-like fields
-* Response body structure or message texts on failed requests (``4xx``, ``5xx`` response codes)
-
-We treat the following types of changes as *backwards-incompatible*:
-
-* Type changes of fields in API responses
-* New required input fields for an API endpoint
-* New required type for input fields of an API endpoint
-* Removal of endpoints, API methods or fields
-
-Pagination
-----------
-
-Most lists of objects returned by pretix' API will be paginated. The response will take
-the form of:
-
-.. sourcecode:: javascript
-
-    {
-        "count": 117,
-        "next": "https://pretix.eu/api/v1/organizers/?page=2",
-        "previous": null,
-        "results": […],
-    }
-
-As you can see, the response contains the total number of results in the field ``count``.
-The fields ``next`` and ``previous`` contain links to the next and previous page of results,
-respectively, or ``null`` if there is no such page. You can use those URLs to retrieve the
-respective page.
-
-The field ``results`` contains a list of objects representing the first results. For most
-objects, every page contains 50 results. You can specify a lower pagination size using the
-``page_size`` query parameter, but no more than 50.
-
-Errors
-------
-
-Error responses (of type 400-499) are returned in one of the following forms, depending on
-the type of error. General errors look like:
-
-.. sourcecode:: http
-
-   HTTP/1.1 405 Method Not Allowed
-   Content-Type: application/json
-   Content-Length: 42
-
-   {"detail": "Method 'DELETE' not allowed."}
-
-Field specific input errors include the name of the offending fields as keys in the response:
-
-.. sourcecode:: http
-
-   HTTP/1.1 400 Bad Request
-   Content-Type: application/json
-   Content-Length: 94
-
-   {"amount": ["A valid integer is required."], "description": ["This field may not be blank."]}
-
-If you see errors of type ``429 Too Many Requests``, you should read our documentation on :ref:`rest-ratelimit`.
-
-Time Machine
-------------
-
-Just like our shop frontend, the API allows simulating responses at a different point in time using the
-``X-Storefront-Time-Machine-Date`` header. This mechanism only works when the shop is in test mode.
-
-Data types
-----------
-
-See :ref:`data types <rest-types>` of the REST API.
