modifying an existing access token permissions

Question

I've got an facebook application which is using an access token to set/get posts from facebook. I want to add a new permission to this access token, is there any way i can do so? (i want to add the rsvp_event permission)

Answer 1

You cannot add permissions to an existing token, because the users need to accept them.

So you need to ask for a new token with this additional permission, and your users will need to accept it before you get the new generated token.
