How can I retrieve the list of Facebook users that have clicked the like button on an external site?
Say I have a like button:
<fb:like href="http://example.com/xyz"></fb:like>
I'd like a list of FB user IDs of people who have liked it.
I've tried OpenGraph:
https://graph.facebook.com/OBJECTID/likes/
(where OBJECTID is the id of the like example.com/xyz)
and FQL
select user_id from like where object_id in (
select id from object_url where url = 'http://example.com/xyz'))
but both return empty results.
I can see from other calls that the likes are counted alright, but I can't get the actual users.
Anyone know what permissions etc. I'd need to retrieve these?
Also see this question for sample code.
The simple answer is 'Its not possible to get individual user ids who liked a page'.
https://graph.facebook.com/cocacola/likes?access_token='xxxxxxxxxxxxxxxxxxxxxxx'
will surely return the data about the likes from the user/page but not the list of users who liked the specific object(in this case coca-cola). But make sure you send a proper access_token with proper permissions.
The FQL like is used to get the likes of any objects like video, note, link, photo, or album. To get liked users count of a page please use either link_stat or page from FQL.
the sample query will be like
SELECT url, normalized_url, share_count, like_count, comment_count, total_count,
commentsbox_count, comments_fbid, click_count FROM link_stat WHERE url="facebook.com"
SELECT name, fan_count FROM page WHERE page_id = 19292868552
