Token lifecycle
Each authorization token is valid for 1 hour from the time it is generated.
To limit unnecessary token generation, the authentication endpoint reuses an existing token when possible:
- More than 5 minutes of validity remaining: the existing token is returned with its original
expires_at. - No active token, or 5 minutes or less of validity remaining: a new token is generated with a new 1-hour validity period.
Integrations should store both authorization_token and expires_at, and reuse the current token until it approaches expiration.
Recommended renewal strategy
Request authentication again approximately 4 minutes before
expires_at. This ensures the request falls within the renewal window while avoiding unnecessary authentication calls.
Early authentication calls
Calling the authentication endpoint before the renewal window does not extend the validity of the current token. The existing token and its original
expires_atare returned.
