Queues add/reactivate/owner changes and optional staff tasks, rechecking donor access per record. Repeat the same Idempotency-Key and preview token to recover its operation. A consumed/expired preview, concurrent application or changed definition returns 409. Does not send communication. Requires event setup management; archived event invitation history is read-only (409). ## OpenAPI ````yaml post /admin/events/{eventId}/invitees/selection/apply openapi: 3.0.0 info: title: Gratona API description: >- REST API for the Gratona fundraising platform, including donor, donation, sponsorship, program, event, and integration workflows.
