Question

I have an app (or link really) that allows my customer to share a certain product to their wall/timeline through this protocol:

http://www.facebook.com/dialog/feed?app_id=APP_ID&link=….

Upon successful share, the customer gets a coupon code, once he/she is directed back to my site.

I’d like to be able to verify the existence of the share post to determine if the rebate code is valid or not. I have the post id, looking like this:

704745000_513399762010000 (random example)

I kind of figured out that I need permission to query for a specific post using graph-api in a users timeline, but how can I get the permission? Any pointers and examples (in php) are appreciated, thanks.

Answer 1

You can use the php sdk to both: create the post, get a returned id to store in database and authenticate user to your application.

there is a login and api request sample included in the sdk.
