Delayed request for open graph permissions.

Question

I have an app which never requested for open graph permission to post to the wall.
But now I am in the process of integrating open graph and realized that I need to request publish actions.

Now if I add the public actions permissions to the app, how does facebook request it from existing users who approved without this perm?

Answer 1

when your existing user returns, it will ask for just publish_actions permission if rest of the required permission he has already given.
