Steps
Distinguish Admin API tokens (community-admin-scoped, generated in Developers > Tokens) from Headless Auth tokens (short-lived, member-scoped JWTs minted via the Auth API).
Use Admin tokens for server-side automations, migrations, or admin-privileged scripts.
Use the Headless Auth API to exchange admin-level credentials for a member-specific JWT when building features that act on behalf of a signed-in member (e.g. posting from your own app on that member's behalf).
When generating credentials in the Circle admin UI, explicitly select the 'Headless Auth' token type rather than a standard Admin token, since they are not interchangeable.
Confirm the community's plan tier (Business+) before assuming either API family is available, and check current per-plan usage limits.
Known gotchas
Never embed Admin tokens in client-side code — only short-lived Headless member JWTs are safe for that purpose.
Headless and Admin APIs are documented and versioned separately (api.circle.so/apis/headless vs. api.circle.so/apis/admin-api) — cross-referencing the wrong doc set causes invalid-endpoint errors.
Rate/usage limits differ by plan tier even within Business+, so high-volume use cases should be checked against current limits before launch.
