Reply on a support request
Platform module
POST/support-tickets/{id}/replysupportTickets.reply
Adds a message as the requester or a responder (app.post_support_message). A closed request takes no messages (support_ticket_closed: 422); a requester's reply reopens a waiting request. Requires `Idempotency-Key`; a replay returns the original response. A rule that refuses the request returns 422 with `refusal` and `reason`.
- Requires the capability me.account.write.
- OAuth scopes: me.
- Send an Idempotency-Key header. A replay with the same key returns the original response.
- Error statuses: 400, 401, 404, 409, 422, 429. Errors are RFC 9457 problem details.
