client_id — Client ID

Location: payload · Format: string

Identifies the OAuth client the access token was issued to — distinct from aud, which names the resource server(s) the token may be presented to. A resource server should treat this as informational context, not as an authorization decision input on its own.

Defined in RFC 9068 §2.2.
