Sohaib Ilyas's video: Facebook PHP SDK v5: Deauthorize Callback URL - Part 28

Someone asked for this video that how we can keep track of the users who are deauthorizing the app manually from their Facebook account settings so I decided to make a video on this topic that how we can check if user has deauthorized your app. Actually when user remove your app manually then Facebook can send a ping to a URL specified by you in the app settings with the parameter "signed_request" which has the information "user_id" so we can check which user has removed your app by getting the user ID using the code shown in the video. • Facebook Official Doc: https://developers.facebook.com/docs/games/gamesonfacebook/login • Subscribe Me: http://sohaibilyas.com/subscribe • Facebook: http://sohaibilyas.com/facebook • Twitter: http://sohaibilyas.com/twitter • Website: http://sohaibilyas.com
