Mark People Back

Record who has come back from a departure. A person must be checked in on the departure, and the departure must have started, before they can be marked back. This is the Back button staff press on Today, the session's manifest and the mobile app.

• Mark one person back, undo it, mark everyone on one booking back (people not named yet included), or mark everyone still out on the departure back.
• When the last person out is marked back, the departure is completed, as Complete Schedule does.
• A booking that runs on several days is counted day by day: each departure has its own Back.

Endpoints

POST   /v1/experiences/{id}/schedules/{scheduleId}/participants/{participantId}/back
DELETE /v1/experiences/{id}/schedules/{scheduleId}/participants/{participantId}/back
POST   /v1/experiences/{id}/schedules/{scheduleId}/bookings/{bookingId}/back
POST   /v1/experiences/{id}/schedules/{scheduleId}/back

DELETE undoes one person's Back: they read as still out again. It works on someone a member of staff marked back. Once the departure was finished by Complete or at its end time, everyone on it stays back and DELETE answers 422.

Authentication

Requires an API key with the bookings:write scope.

  "data": {
    "schedule_id": 487,

out_count is people checked in on the departure and not marked back yet. It never counts anyone who did not check in. session_finished is true when this call marked the last person back.
