REST API

Track changes to the Band REST API including new endpoints, breaking changes, and deprecations.

Changed

  • Breaking: Stricter Request Validation — All API endpoints now reject requests containing unexpected properties. Previously, extra fields in request bodies were silently ignored.

Action Required

If your integration sends fields not defined in the API schema, requests will now return a 400 Bad Request error. Review your API calls and remove any extra properties not documented in the API reference.
