  title: SWITCH edu-ID OpenID Connect (UZH Federated Identity) Discovery API
  description: OpenID Connect / OAuth 2.0 provider operated by SWITCH edu-ID and used by the University of Zurich as its central federated identity. This OpenAPI document is derived faithfully from the published OpenID Connect Discovery document at https://login.eduid.ch/.well-known/openid-configuration and the matching JWKS endpoint. Only endpoints, parameters, scopes, and claims actually advertised by the discovery document are represented here. Authorization Code flow with PKCE (S256) is the supported interactive flow; refresh_token is supported for token renewal.
