Refresh Token

A token used to obtain a renewed access token without having to re-authenticate the user.


  • The grant_type parameter should always have a value of refresh_token in this flow and the value of the refresh_token parameter should be the actual refresh token obtained by the client after some other flow.

Requesting a token using the refresh_token Grant Type

The RequestRefreshToken extension method has convenience properties for the refresh_token grant type:

var response = await _client.RequestRefreshTokenAsync(new RefreshTokenRequest
    Address = TokenEndpoint,

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

    RefreshToken = "xyz"
