UserInfo Endpoint

The client library for the OpenID Connect UserInfo endpoint is provided as an extension method for HttpClient.

The following code sends an access token to the UserInfo endpoint:

var client = new HttpClient();

var response = await client.GetUserInfoAsync(new UserInfoRequest
{
    Address = disco.UserInfoEndpoint,
    Token = token
});

The response is of type UserInfoResponse and has properties for the standard response parameters. You also have access to the raw response and to a parsed JSON document (via the Raw and Json properties).

Before using the response, you should always check the IsError property to make sure the request was successful:

if (response.IsError) throw new Exception(response.Error);

var claims = response.Claims;
