Gallery Platform API
Reference

Check a ticket in

Admits a ticket into a session — from a scanned QR payload or a ticket id. Idempotent: re-scanning an already-admitted ticket returns its existing check-in, so a flaky scanner or an offline replay is safe. Void or refunded tickets are refused.

Header Parameters

Idempotency-Key?string

Optional. Send a unique key per logical operation to make retries safe: a retry with the same key replays the stored success for 14 days instead of re-running the write. Reusing a key with a different body returns 400.
