Currently, when a person authorizes your application, your application is able to make requests for the person’s data on their behalf. This includes the ability to retrieve a limited amount of the person’s friends’ data according to each friend’s privacy settings.
Beginning on September 15, 2016, your application will only be able to access the data of the person who authorized your application regardless of the person’s friends’ privacy settings. API requests for a user id other than the user represented in an access token will receive a 401 Unauthorized error.
