55. Karlsruhe Service Research Institute www.ksri.kit.edu Data Access Permissions There are 79 data access permissions in FB in 3 categories: User Data Permissions Friend Data Permissions Extended Permissions They regulate what you can and cannot access 55

57. Karlsruhe Service Research Institute www.ksri.kit.edu FB JSON Objects Everything in FB is accessed via an ID Users, Pages, Events, Comments, Posts, Shares, To view / access the JSON object for a FB entity: https://graph.facebook.com/?auth_token= Auth Token? Access Token An access token is an opaque string that identifies a user, app, or page and can be used by the app to make graph API calls. It is valid only for a predetermined period of time A log out action will automatically expire an access token Every time you log into FB, you create an access token More info: http://developers.facebook.com/docs/facebook-login/access-tokens/ 57
