A human Org Admin manages the service accounts of their own organization: create, read, update, and enable/disable (there is no delete — an account is disabled instead), and issue, rename, re-date, enable/disable, and revoke each account's API keys. An API key is an `fks_` secret that inherits the account's grants and cannot manage service accounts; an active, unexpired key must be disabled before it can be revoked, and it authenticates only while both it and its account are active. Scopes here are capability scopes (what the account may do), not OAuth scopes. - name: sessions-v3 description: v3 session APIs - name: team-roles-v3 - name: team-v3 - name: traces-v3 description: v3 trace api for monitoring - name: fetch-sessions-v3 description: v3 fetch sessions api for monitoring - name: user-access-key description: > CRUD operations for user API keys.
