Naming note

Older internal / platform notes may mention dotted names such as registration.approved or attendance.check_in. Treat those as non-canonical. Integrators should subscribe to and verify the UPPER_SNAKE names above.

Payload shapes

See Payload examples for JSON envelopes and field notes.

Best practice

Subscribe only to events you handle — reduces noise, retries, and verification load.
