  title: OpenID Connect (OIDC) SSO Authentication Logout API
  description: The OpenID Connect (OIDC) API is a lightweight identity layer built on top of OAuth 2.0 that enables applications to verify user identity and obtain basic profile information. OIDC defines standard endpoints including the Authorization Endpoint, Token Endpoint, UserInfo Endpoint, and JWKS URI. It supports Authorization Code Flow, Implicit Flow, Hybrid Flow, and PKCE extensions for public clients. OIDC is widely implemented by identity providers including Okta, Microsoft Entra ID, Google, Auth0, and Keycloak.
