title: Twitter's OAuth is asking my users to copy a PIN at sign in. Can I automate that step with Twitterizer?
body: <p>I'm using Twitterizer. I got my Consumer key and Secret, and told Twitter my callback URL.  However, after the user clicks permit, he gets a PIN to manually copy back to my application. I'm not even sure what I (the developer) am supposed to do with the PIN.  Since the user isn't redirected back to the callback page, I'm not sure when that comes into play either.  </p>
  
  <p>I'm using the project template from 4 guys from Rolla. The callback page is internet visible (i.e. not just running on localhost)</p>
  
  <pre><code>protected string GetTwitterAuthorizationUrl()
  {
      string ConsumerKey = ConfigurationManager.AppSettings["ConsumerKey"];
      string ConsumerSecret = ConfigurationManager.AppSettings["ConsumerSecret"];
  
      OAuthTokenResponse reqToken = OAuthUtility.GetRequestToken(ConsumerKey, ConsumerSecret, "oob");
      return "https://twitter.com/oauth/authorize?oauth_token=" + reqToken.Token;
  }
  </code></pre>
  
  <p>Here is the corrected code:</p>
  
  <pre><code>        string CallbackUrl2 = ConfigurationManager.AppSettings["CallbackUrl"]; 
          OAuthTokenResponse reqToken = OAuthUtility.GetRequestToken(ConsumerKey, ConsumerSecret, CallbackUrl2);
          return "https://twitter.com/oauth/authorize?oauth_token=" + reqToken.Token;
  </code></pre>
