Account API keys work in every workspace you belong to: send X-Notra-Organization-Id with the workspace id or slug to choose one.

Organization keys only accept their own workspace there. ```` This documentation is built and hosted on [Mintlify](https://mintlify.com), a developer documentation platform.
