Dear Friends,
I am using https://api.login.yahoo.com/oauth/v2/request_auth (reference : http://developer.yahoo.com/oauth/guide/oauth-userauth.html) to present a login and authorization page to the user.
Even if the user is already given permission for the app, it asks again when the user next time login.
How to make sure that if a user is already autorized the app, he is not required to authorize again?
Regards,
Meenu
