What is an access token?

An access token is a credential an application presents to an API to prove it has been granted specific, scoped access; it is typically short-lived.

Frequently asked questions

Why are access tokens short-lived?

Limiting the lifetime reduces the damage if a token is ever intercepted or leaked.

Can an access token be reused across different APIs?

Not securely; resource indicators (RFC 8707) restrict a token's audience to the specific resource it was issued for. See resource indicators.

Building the integration, not choosing it?Definitions stop where implementation starts. The developer docs carry the API references, SDKs and SCIM endpoints.
