We have an android app where user can sign in using twitter.
Now the user posts something to the server and I need to verify that the twitter username really is authenticated through twitter and token is not expired.
I can not find anything in the api that support this scenario?
The verify credentials(https://dev.twitter.com/docs/api/1.1/get/account/verify_credentials) requires the user to be authenticated on the server.
I believe it would be possible through reverse oauth(https://dev.twitter.com/docs/ios/using-reverse-auth) but it requires IOS.
I would need something like this https://developers.google.com/accounts/docs/OAuth2UserAgent#validatetoken
