Cancel an appointment by setting its status to cancelled. Only appointments that have not yet had their blood draw confirmed can be cancelled. Cancelling an appointment that is already cancelled returns 200 with that appointment, and writes nothing — no second cancellation is recorded. The response carries Idempotent-Replayed: true so you can tell a repeat from the call that did the work. A repeat that carries a different cancellation_reason returns 409 instead: the recorded reason is never overwritten. See Idempotency.

Appointments cannot be cancelled after the blood draw has been confirmed — that returns 409 Conflict.

Requires the test_sessions_schedule or test_sessions_manage scope.
