CALL NUMBER: oauth_2_0_and_openid_connect.token_endpoint : deep_oauth_2_0(1)
DEFINITION: OAuth 2.0 endpoint accepting authorization_code or other grants and returning access_token, refresh_token, and optional id_token.
Invoke this skill to understand token_endpoint down to its primitives. The RELATIVE ROOT below is the least-fixed-point closure of everything it bundles from — the full import cone, grouped by the lib each prim comes from. Projected from a prover-typed KB (MAP/SWI-Prolog consistency gate): every reference below resolves.
THE RELATIVE ROOT (the import cone, by lib)
from ?
- token_type (d1): OAuth 2.0 parameter indicating how the access_token is to be presented to the resource server, typically Bearer, specifying the authorization scheme to use in requests.
from deep_oauth_2_0
- access_token_scope (d2): The specific permission set granted to the access_token; a space-delimited string drawn from the scopes requested and approved during authorization; determines what resources and actions the token authorizes.
from oauth_2_0_and_openid_connect
- access_token (d1): OAuth 2.0 credential presented to the resource server; opaque to clients but contains or references authorization state; scoped and time-limited.
- expires_in (d1): Integer seconds indicating access token lifetime; returned alongside access_token in token response.
- authorization_server (d2): OAuth 2.0 server that authenticates the resource owner, obtains consent, and issues access tokens and optionally refresh tokens and ID tokens.
- bearer_token (d2): Token type defined in RFC 6750; any party possessing the token may use it; security relies on transport TLS and token secrecy.
- grant_type (d2): OAuth 2.0 parameter identifying which authorization flow is being used; values: authorization_code, client_credentials, refresh_token, password (deprecated).
- introspection_endpoint (d2): RFC 7662 endpoint allowing resource servers to validate access tokens; returns active status, scope, expiry, and other token metadata.
- refresh_token (d2): OAuth 2.0 credential used to obtain new access tokens without re-prompting the resource owner; long-lived and tied to the same scope as the original access token.
- resource_indicator (d2): RFC 8707 parameter specifying the target resource server URI; server issues access token scoped to that specific resource, not just the general API.
- resource_server (d2): Server hosting protected resources; validates incoming access tokens and returns resources only when tokens are valid and authorized.
