title: Yahoo is unable to process your request 95022, OAuth2 authentication error
body: <p>I'm trying to use Yahoo's developer APIs in Xamarin Studio's Xamarin Auth component.  I created my app in with Yahoo's Developer tools, set my permissions to read everything, but can't get authorization.  I get the following error.  </p>
  
  <p>Oops.  Yahoo is unable to process your request.  We recommend that you contact the owner of the application or web site to resolve this issue. [95022] </p>
  
  <p>Below is my code</p>
  
  <pre><code>        string clientId = "&lt;application id from developer.apps.yahoo.com&gt;";
          string scope = "";
          Uri authorizeUrl = new Uri("https://api.login.yahoo.com/oauth2/request_auth");
          Uri redirectUrl = new Uri("http://www.website.com");
          var auth = new OAuth2Authenticator(clientId, scope, authorizeUrl, redirectUrl);
  
          auth.Completed += (sender, eventArgs) =&gt; {
              Console.WriteLine("Completed!");
              Console.WriteLine("eventArgs.IsAuthenticated = " + eventArgs.IsAuthenticated);
              DismissViewController (true, null);
              if (eventArgs.IsAuthenticated) {
                  // Use eventArgs.Account to do wonderful things
  
              }
          };
  
  
          PresentViewController(auth.GetUI(), true, null);
  </code></pre>
  
  <p>Any ideas as to what I'm doing wrong here?  </p>
  
  <p><strong>-------------- Update --------------</strong></p>
  
  <p>I wasn't able to get OAuth2 in Xamarin.Auth working with Yahoo, but I did get OAuth1 functional.  I ended up not even using that component and instead using another implementation of OAuth that was documented in the Yahoo Developer Documentation with OAuth and BOSS found here</p>
