One of my Facebook apps allows users to share a URL to a Facebook event using the default Facebook sharer. I was under the impression that you can query for the number of times such a URL got shared on Facebook. However, when I query the Graph API for some very popular events on Facebook I get results that show me 0 shares, likes and comments.
E.g.
SELECT click_count, comment_count, comments_fbid, commentsbox_count, like_count, normalized_url, share_count, total_count, url
FROM link_stat
WHERE url = 'http://www.facebook.com/events/385623724876261'
Returns
{
"data": [
{
"click_count": 0,
"comment_count": 0,
"comments_fbid": null,
"commentsbox_count": 0,
"like_count": 0,
"normalized_url": "http://www.facebook.com/events/385623724876261",
"share_count": 0,
"total_count": 0,
"url": "http://www.facebook.com/events/385623724876261"
}
]
}
How can I query Facebook for the real number of times a URL to a Facebook event got shared?
Thanks.
