+
+   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.
+
+   .. warning:: This endpoint is considered **experimental**. It might change at any time without prior notice.
