Using the Facebook Graph API

App tokens

For server-to-server requests to the Facebook Graph API you can skip requesting an Oauth token, an instead use the combination of app_id|app_secret as your access token. This token will never expire, and should suffice for retrieving basic information from the Graph API.

Since you don't make requests for a certain user, the Graph API might respond with an error in case you're requesting a resource that requires authenticating as a human being.
