Atlassian Identity

Twin of Atlassian Cloud's OAuth 2.0 (3LO) authorization server.

The 3LO authorization server on auth.atlassian.com. It mints the access tokens the Jira twin verifies.

Coverage

Two grants: authorization code and rotating refresh token. Client credentials is refused the way Atlassian refuses it. The endpoints behind them are authorize and token, and nothing else: Atlassian publishes no discovery document, no userinfo and no product resources on this host, so a client library that bootstraps itself from /.well-known/openid-configuration finds none here either. Jira’s own API traffic goes to the Jira twin.

This twin is added to your environment automatically when you ask for Jira, so you rarely request it directly.

Credentials

Any well-formed client id and secret authenticate by default; a missing one is always refused. Set auth.mode to enforced to accept only the client the world lists. See Credentials.

Vendor specific details

  • Refresh tokens rotate on use. Presenting a superseded refresh token again within ten minutes returns the same replacement pair instead of invalid_grant, so a retried refresh is safe. After that window it is refused. A refresh token’s hard lifetime is 90 days.
  • The code exchange reads client credentials from the body only. HTTP Basic on that grant is refused, while the refresh grant accepts either placement.
  • audience=api.atlassian.com is required on authorize. Anything else is invalid_request with “audience is invalid”.
  • A GET /authorize with no query string at all redirects to the Atlassian login page before validating anything, so an empty request looks like it worked.

Its own notes

Once a sandbox is running, this twin serves its own operating notes at {control_url}/veris/manual: the credentials it accepts, the API versions it serves, and the fault statuses you can arm against it. They are generated from the same source as its behaviour, so they cannot drift.
