    • urn:ietf:params:oauth:grant-type:device_code

    • extension grant

.NET client library

You can use the IdentityModel client library to programmatically interact with the protocol endpoint from .NET code.

using IdentityModel.Client;

var client = new HttpClient();

var response = await client.RequestAuthorizationCodeTokenAsync(new AuthorizationCodeTokenRequest
    Address = TokenEndpoint,

    ClientId = "client",
    ClientSecret = "secret",

    Code = "...",
    CodeVerifier = "...",
    RedirectUri = ""
