And is authenticated through the oAuth 2.0 protocol by the auth server. After successful authentication the Api redirects back to the Frontend / CMS with a JWT token in the url that the frontend server can use for authenticating requests. Like so: `X-Authorization: Bearer JWT` Named `X-Authorization` so it won't collide with Basic Authentications headers. Following urls can be used to get user info with the JWT token. `GET /oauth/site/:SITE_ID/me` --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
