We want to have a simple Facebook php app with these simple features on it:
- add an initial dialog (authentication) box to get user's permissions. It needs to be protected against XSS (CSRF) as stated in the example here [url removed, login to view]
- add a button on the main app page to make payments with FB credits
The application should be optimized for speed and commented
The content itself will be added by us. We just need the skeleton
Just to make things clear, the Graph API should be used
Please no deprecated Facebook technologies...
