}Unsend a message
Unsends a text-only iMessage you sent from this workspace. Apple allows this within 2 minutes of sending. Recipients on older Apple software may still see the message.
The message stays readable through the API with unsent_at and unsent_scope set, and its text is removed from parts. The unsent text is never returned. Repeating an unsend returns the current message. Send an Idempotency-Key so you can safely retry.

}Authorizations
Your workspace API key, sent as Authorization: Bearer blu_.... Workspace admins can find it in the Blujay app under API.
An API key has full access to your workspace and works on every endpoint. There is no test mode: every key sends real messages and changes real data, so keep it secret and use it only from your server.
Each API key can make 600 read requests and 120 write requests per minute, plus 60 attachment requests per minute. Over a limit you get 429 RATE_LIMIT_EXCEEDED with Retry-After.
Headers
A unique value you choose (1–255 characters) that makes this request safe to retry. Send the same key with the same request and Blujay returns the original response instead of doing the work again. Use a new key for each new action.
Blujay keeps keys for at least 24 hours. Keys are separate for each API key and each route family (for example every POST /v1/chats/{chat_id}/messages shares one). Reusing a key with a different request returns 409 IDEMPOTENCY_REQUEST_MISMATCH. Sending it while the first request is still running returns 409 IDEMPOTENCY_IN_PROGRESS; retry shortly.

Response
The message after the edit or unsend. If the same change was already in place, the message is returned unchanged.
Wraps every successful response. The result is in data.

Your X-Request-ID header value, echoed back when you send one. Not included on the send responses (POST /v1/chats, POST /v1/chats/{chat_id}/messages, POST /v1/messages/{message_id}/retry); keep your own mapping from your request ID to the returned message ID there.
