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`. **Reseller partner keys.** A partner key acts for one of the partner's customers when the request names it in the `Blujay-Workspace` header (the customer's `workspace_` ID). Without the header it reaches only `/v1/partner/*` and `/v1/me`. Each customer gets the limits above for each partner key, and all of a partner's requests together get ten times those limits; a `429` says which in `error.details[0].scope` (`partner_customer` or `partner`). A `messaging` key can read anything for a customer and change chats, messages, contacts, attachments and vCards; everything else needs an `admin` key (`403 PARTNER_ROLE_FORBIDDEN`). Paused or closing customers can be read but not changed (`409 CUSTOMER_PAUSED` or `CUSTOMER_CLOSING`). Any other workspace ID in the header returns `404 NOT_FOUND`; using the header with any other credential returns `400 WORKSPACE_HEADER_NOT_ALLOWED`. ```` This documentation is built and hosted on [Mintlify](https://mintlify.com), a developer documentation platform.
