We have a Facebook app that manages user business pages, we are using webhooks to subscribe to 'feed' event for access comments. Our application has 7 days free trial after that the account becomes inactive and may be deleted from our database. But since the user didn't delete our app from his current apps in Facebook, we
still getting his events through webhooks
, this way we are keep getting calls from webhook for all our old deleted users. I couldn't find any way to unsubscribe webhook calls for a specific user of the app. Like the way user deletes app permissions from his Facebook dashboard, is there a way an app can also make a user invalid for that app?
