This seems like a pretty obvious, basic thing to expect from the Graph API, but I'm having serious difficulty with it. All I want to do is get the ID for any particular URL. They have a method for this:
https://graph.facebook.com/?ids=http://www.imdb.com/title/tt0117500/
And that works great. But if I try another URL, say for my blog,
https://graph.facebook.com/?ids=http://dusda.vox.com
it doesn't give me back a numerical ID like all of the examples do. Instead, this:
{"http:\/\/dusda.vox.com":{"id":"http:\/\/dusda.vox.com"}}
If I try to use that "id", I get jack (probably because the query string looks impossible to parse):
Request: https://graph.facebook.com/http://dusda.vox.com/likes
Response: {"id":"http:\/\/dusda.vox.com\/likes"}
So what's up with this? Is the Graph API just selectively reliable, or am I misunderstanding something? I've tried it on URLs that I know are popular on Facebook, too, and I've gotten mixed results.
The ID is given by Facebook only to pages which have a fbshare/like button. Else the API returns the number of shares and the request URL.
Try FQL for this;
http://graph.facebook.com/fql?q=select%20url%2C%20id%2C%20type%2C%20site%20from%20object_url%20where%20url%20%3D%20%22http%3A%2F%2Fkriek.hu%2F%22
returns:
{
"data": [
{
"url": "http://kriek.hu/",
"id": 497425470154,
"type": "link",
"site": "kriek.hu"
}
]
}
For more information, see object_url.
I hope it helps!
If I use the facebook object debugger page I can scrape every url, for example:
https://developers.facebook.com/tools/debug/og/object?q=ddnl.de
The page give me back an url with ID and so I can get every needed parameters.
In this case https://graph.facebook.com/10150164108649475
But I don't get this ID or url with FQL or otherwise?
Very old question, but here's what I found works for me as none of the answers here really resolved my issue:
If you have a custom object tied to a url, the method suggested by Pepe only gives the id FB assigns to the url where type=link. (Which is not tied to any comments)
In my case, I need my custom object id so that I could pull associated comments from it. You can get the object id using FQL by doing a select on 'comments_fbid' from the 'link_stat' table. (This will return the object id even if no comments have been added so it should work for other cases)
At this time no of the suggested solutions work for all urls. Only the Debugger is able to get the Graph ID correctly
For example
For URL: www.amazon.de/gp/product/3442465583/
Result: https://graph.facebook.com/10150771435736113
{
"url": "http://www.amazon.de/dp/3810510793/ref=tsm_1_fb_lk",
"type": "book",
"title": "Die unwahrscheinliche Pilgerreise des Harold Fry: Roman",
"image": [
{
"url": "http://ecx.images-amazon.com/images/I/51I4E81xrRL._SL160_.jpg"
}
],

}
I had the same problem here, I was trying to get the same data IMDB gets. After almost bang my head against the wall, I decided to look at the facebook's js function. And look what I get, the explanation is on the link.
