Check-in lists¶

Resource description¶

You can create check-in lists that you can use e.g. at the entrance of your event to track who is coming and if they actually bought a ticket.

You can create multiple check-in lists to separate multiple parts of your event, for example if you have separate entries for multiple ticket types. Different check-in lists are completely independent: If a ticket shows up on two lists, it is valid once on every list. This might be useful if you run a festival with festival passes that allow access to every or multiple performances as well as tickets only valid for single performances.

The check-in list resource contains the following public fields:

GET /api/v1/organizers/(organizer)/events/(event)/checkinlists/(list)/positions/(id)/¶

Returns information on one order position, identified by its internal ID. The result is the same as the Order position resource, with the following differences:

Parameters:	organizer – The slug field of the organizer to fetch event – The slug field of the event to fetch list – The ID of the check-in list to look for id – The id field of the order position to fetch

POST /api/v1/organizers/(organizer)/events/(event)/checkinlists/(list)/positions/(id)/redeem/¶

Tries to redeem an order position, identified by its internal ID, i.e. checks the attendee in. This endpoint accepts a number of optional requests in the body.

Instead of an ID, you can also use the ``secret`` field as the lookup parameter.

Request JSON Object:

questions_supported (boolean) – When this parameter is set to true, handling of questions is supported. If you do not implement question handling in your user interface, you must set this to false. In that case, questions will just be ignored. Defaults to true. canceled_supported (boolean) – When this parameter is set to true, the response code canceled may be returned. Otherwise, canceled orders will return unpaid. datetime (datetime) – Specifies the datetime of the check-in. If not supplied, the current time will be used. force (boolean) – Specifies that the check-in should succeed regardless of previous check-ins or required questions that have not been filled. Defaults to false. ignore_unpaid (boolean) – Specifies that the check-in should succeed even if the order is in pending state. Defaults to false and only works when include_pending is set on the check-in list. nonce (string) – You can set this parameter to a unique random value to identify this check-in. If you’re sending this request twice with the same nonce, the second request will also succeed but will always create only one check-in object even when the previous request was successful as well. This allows for a certain level of idempotency and enables you to re-try after a connection failure. answers (object) – If questions are supported/required, you may/must supply a mapping of question IDs to their respective answers. The answers should always be strings. In case of (multiple-)choice-type answers, the string should contain the (comma-separated) IDs of the selected options.
