}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.
Path Parameters
Pattern:
^att_[A-Za-z0-9_-]+$Example:
"att_abc123"
Response
The attachment is deleted. Deleting it again also returns 204.
