OIDC

OpenID Connect (OIDC) is an identity layer built on top of OAuth 2.0 that enables clients to verify the identity of end-users based on authentication performed by an authorization server. It provides a standardized way to obtain basic profile information about users through RESTful endpoints including discovery, authorization, token, userinfo, and JWKS.

OIDC publishes 6 APIs on the APIs.io network, including Authentication API, Discovery API, JWKS API, and 3 more. Tagged areas include Authentication, Identity, JWT, OAuth, and OIDC.

The OIDC catalog on APIs.io includes 1 Spectral governance ruleset.

OIDC’s developer surface includes authentication, documentation, engineering blog, and 4 more developer resources.
