Glean-issued API token bearer Get token ↗

Find your tenant server URL at About Glean. Then in Glean Admin, go to Settings → API Tokens to create a token. Use this token for Client API calls, and for Indexing API calls as the only supported auth method. Global Client API tokens require impersonation with X-Glean-ActAs; user-scoped tokens do not.

Set up a Client API OAuth app using Glean's OAuth authorization server as described in OAuth Authentication for Client API. Use Authorization Code with PKCE, either with a static client or Dynamic Client Registration. Obtain an access token for your tenant's Client API; Glean-issued OAuth tokens do not require X-Glean-Auth-Type.
