I created my application and would like to know how other users can access this application to add it to your twitter accounts. I’ve converted the request token to an access token and retrieved the PIN and used it in the app code. After that when the user tries to register with the app, he gets the PIN displayed again and so I’ve to edit my app code and mention this new PIN. How to stop the PIN retrieval? I then changed the Callback URL to stop the PIN retrieval and now when the user authorizes the app the app isn’t mentioned in his twitter application list. What is the matter?
