Facebook will limit access to third-party apps to user information, which they share in events and groups in the social network.
Employees noted that have already started to operate the new rules. Now third party apps will not access the guest list or post on the wall of the event or group. To get access to this information, the application will have to obtain confirmation from Facebook, and it will have to agree to stringent specifications and, of course, to implement them.
In addition, Facebook will no longer allow applications to request access to your personal information.
