Class AuthorizationCodeFlow (1.50.0)

public class AuthorizationCodeFlow : object, IAuthorizationCodeFlow, IDisposable

Thread-safe OAuth 2.0 authorization code flow that manages and persists end-user credentials.

This is designed to simplify the flow in which an end-user authorizes the application to access their protected data, and then the application has access to their data based on an access token and a refresh token to refresh that access token when it expires.
