+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.

+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.
