With Facebook API, within a custom app added to a fanpage, how do I recognize the fanpage ID?
Here's what I'm trying to achieve:
- user goes to the full-width canvas app, he authorizes himself there and allows the app to add a tab to one of the fanpages he's administrating
- every Facebook user going to that fanpage, sees the tab and the tab contains content specific to that fanpage (that's why I need to know the fanpage ID)
- if fanpage administrator wants to change something, he goes to the full-width canvas and logs in to my service (here's where I store what he wants to show in his Fanpage)
