I have the read_stream access from user, I want to award him some points if he shares one of my pages' post. Now I have Claim Point button so I can crawl his posts, and I want to check if he has shared my page's post (using Share link of Facebook, near Comment and Like ). I had an Idea, if someone shares others' post it appears as a link, so I tried to match the link with my page's link, but if its a Facebook link (or post like status, note) then url form below FQL returns null. Same happens with Graph API (link doesn't appear).
select url,link_id,title from link where owner=me()
It works fine if its an external link (which is not helpful for me).
So what's the problem here? And I am open to other ideas, to check if user has shared my post.
Any help is appreciated.
I have found a solution. Normal calls don't return Shared Posts' links at all. But Feed returns, so crawling feed makes my task done.
https://graph.facebook.com/me/feed/?access_token=your_access_token
Nice way but will only work in Graph API 1.0
Some test in the Graph explorer looks quite clean
https:/graph.facebook.com/me/feed/?fields=link,story,status_type&limit=100&status_type=shared_story
Now parse the link if it contains the Page ID or your domain . If the last 100 post have more than one share from the page he get ranked up or some Superpoints .
Thank you Usman for the hint in the right direction
