GET

• Filters: timeslot_id, registrant_id, checked_in, created_from, created_to, updated_from, updated_to, sponsor_id.

GET .../rsvps?checked_in=true&include=timeslot,registrant

POST inputs: timeslot_id, registrant_id. Use PATCH to change check-in state.

{
  "timeslot_id": 5501,
  "registrant_id": 1201
}

PATCH input: checked_in_at only.

{ "checked_in_at": "2026-09-03T09:02:00Z" }

Set checked_in_at to null to remove the check-in timestamp. The timeslot and registrant must belong to the event. Sponsor-restricted scopes can create and manage RSVPs only for sponsored sessions. Create and delete use Brella’s attendance-registration services, so capacity and bookmark side effects are preserved.
