End Session Endpoint

The end session endpoint can be used to trigger single sign-out in the browser ( see spec).

To use the end session endpoint a client application will redirect the user’s browser to the end session URL. All applications that the user has logged into via the browser during the user’s session can participate in the sign-out.

The URL for the end session endpoint is available via discovery.

• id_token_hint

  When the user is redirected to the endpoint, they will be prompted if they really want to sign-out. This prompt can be bypassed by a client sending the original id_token received from authentication. This is passed as a query string parameter called id_token_hint.

• post_logout_redirect_uri

  If a valid id_token_hint is passed, then the client may also send a post_logout_redirect_uri parameter. This can be used to allow the user to redirect back to the client after sign-out. The value must match one of the client’s pre-configured PostLogoutRedirectUris.

• state

  If a valid post_logout_redirect_uri is passed, then the client may also send a state parameter. This will be returned back to the client as a query string parameter after the user redirects back to the client. This is typically used by clients to roundtrip state across the redirect.

GET /connect/endsession?id_token_hint=...&post_logout_redirect_uri=http%3A%2F%2Flocalhost%3A7017%2Findex.html

.NET Client Library

You can use the IdentityModel client library to programmatically create end sessions request URLs from .NET code.

var ru = new RequestUrl("https://demo.duendesoftware.com/connect/end_session");

var url = ru.CreateEndSessionUrl(
    idTokenHint: "...",
    postLogoutRedirectUri: "...");
