I want to fetch metadata of any web-page using Facebook Open Graph Object Debugger.
We can get it from this URL: Open Graph Object Debugger
Example: Open Graph Object Debugger for Google
It will provide all the information related to that URL. Is there any way to get this information using API(in JSON format)?
Yes, via the API URL Object described here and in even more detail here. Note that you can issue a POST request to this URL to force a refresh. You can even get additional data such as how many times that link was shared on Facebook!
https://graph.facebook.com/v2.10/?fields=og_object&id=http%3A%2F%2Fwww.imdb.com%2Ftitle%2Ftt2015381%2F&access_token={YOUR_TOKEN}
I did experience inconsistencies, namely if the obejct does not exist the API will return nothing but if you query it a few seconds later it will be there. For this reason we could not rely on Facebook and simply fetched the page ourselves and parsed out the og:* tags.
It may be perfect if you don't care about misses and having to re-fetch or if you just want to programmatically clear the Facebook OG cache.
It's wise to post to it every time you create a new page to force the cache or sometimes the first person to paste the URL into Facebook won't get the link preview!
Yes you can use this https://urlmeta.org
Its usage is pretty simple. Just make a GET call and pass the URL to API endpoint: https://api.urlmeta.org and you are done.
I'am trying to play with the opengraph facebook API. I'd like to fetch my videos by calling /me/videos
I'am using the Opengraph API explorer with a user access token but the response is always empty: {data:[]}
My token is generated with every acces rights (I checked all checkboxes).
/me/photos is working fine, but not /me/videos
Any idea?
Thank you
Depending on your comment I can tell your question doesn't describe what you're looking for. You're not looking for your uploaded/tagged videos, so this endpoint won't work for your case.
Just for information, this endpoint will only return a list of videos that the person is tagged in. You need to specify to this endpoint by adding a type=uploaded parameter to the query if you're also looking for the video uploaded by you.

You're looking for your bookmarked links and it seems the API endpoint to access Facebook "Saved Links" is not available anymore (Is there a way to get the Saved Links?)
I'm trying to submit a fitness.bikes story from a Windows Phone app. Ideally I'd like it to look the same way it does in the documentation -- a table of stats, and a course map. I'm trying to figure out how to make that happen. Specifically, whether it's possible to make it happen without a 3rd party server hosting the ride data.
Questions:
When I am submitting a course object to Facebook, can I specify all needed ActivityDataPoints to make the map show up, or is something else needed?
In the sample post I've been trying, all I get is the Title, the Image, and the Description. Can I get the table of stats to show up, without needing an external server?
The posts I'm sending are not appearing on the Timeline, even for a test user. They do appear in the Activity Log, and are marked with "Allowed on Timeline", not "Showing on Timeline." I'm using fb:explicitly_shared... shouldn't the post show up?
Ok, after further experimentation, I believe I can answer my own questions:
The fitness.bike activity post data should contain only fb:explicitly_shared, privacy, and course links, and nothing else. For some reason adding created_time makes the post appear in standard layout.
Same answer as above. Table of stats is part of the Map layout Facebook provides.
Same answer as above. Removing the created_time attribute magically makes the post appear correctly on the timeline.
P.S. As far as an external server -- it is necessary only if you want to redirect the user to your own page. Even then, the server can grab the object_id from the URL, grab an access token from Facebook using AppID and AppSecret, then lookup that object (course), extract data out of it, and show on the page.
Hope this helps someone else.
Firstly i know that the documentation provided by Facebook says that fb:multi-friend-selector can be used in pair with fb:request-form and that it could only sends inviations or requests.
I have more specific need and that is not only to make invitations/requests but also along with the previous to post something on selected friends walls.
I've tried everything but i cant take the id's selected from the fb:multi-friend-selector, so i'm unable to make this posts.
The doucmentation for fb:multi-friend-selector says: This interface includes a series of which are included for selected users in the form that gets submitted to your action URL.
Is it somehow possible to catch this id's?
I'm working on my app in C# .net.
I read in some of the previous posts that is treating problematics similar to mine that is impossible to do this, but i found application that works perfectly in way that i want to make my application.
Thanks in advance,
Ivan
You can access the selected friend's id in the page that you are providing in "action" of fb:request-form.I am working with PHP so i am able to get those selected friend's id as $_REQUEST['ids'].So try some equivalent methods in c# for this.And if you get the friend's id you can publish to their wall.
I try to fetch user's feeds via graph api from my Android application. It generally works but some feeds that I can see on the wall are missing in the json response.
I call the url http://graph.facebook.com/someUserId/feed, by using the Android Facebook SDK methods, so the access token should be provided automatically, but it's not really relevant I think in my case. Nevertheless fyi, the user of my app is authenticated via OAuth.
I already checked the following:
all the user's feeds are visible to everyone / public (set in privacy settings)
the json response is not cached by my browser
I am aware of paging, but this is not an issue. The problem is not that I am not getting the very oldest feeds but that some feeds are just missing in between.
I registered a new facebook user which is not connected to the user I want to retrieve the wall feeds from, and when I open the respective wall I see all the feeds there, as expected, since they're all public to everyone. Yet, when I open the same related json url unter http://graph.facebook.com/someUserId/feed, some feeds are missing.
This is an example of the problem - since all my posts are public, I can just call the json url directly in a browser to do a test.
I want to get wall feeds from user:
http://www.facebook.com/mathias.lin
Screenshot1: note the 3 marked postings, all posted by myself
and here the json response, as you can see, the 1st and 3rd wall posts are included in the json, but the 2nd post is not. Why?
The related json url is:
http://graph.facebook.com/mathias.lin/feed
I am getting the 'missing' feed when I add an access_token to the url - but why? The posted feed has a privacy setting for 'everyone'?!
This is the missing feed that I get when using the access_token:

I've already posted the question to the FB dev forum, awaiting response.

Facebook Graph API "/userid/feed" returning Blank
Your approach is correct, I've seen the JSON and yes it's missing the second one, I think it's upload app form adroid, try checking the application settings for this app. Or If your trying to retrieve the wall FQL is a much better way
SELECT post_id, actor_id, target_id, message FROM stream WHERE source_id in (SELECT target_id FROM connection WHERE source_id=<uid> AND is_following=1) AND is_hidden = 0
I've been through this, the way Facebook is categorizing their permissions is somehow misleading, for example Publicly available may sounds like Available to everyone on Facebook but apperantly it's not.
Now in your case, if you already authenticated the user, then try using:
/me/feed
I guess this is the only case where access_token is not needed in the URL.
I had a similar problem. But for me, the problem was related to not setting the scope properly on first login (to authorize the app). I posted a similar question and got an answer that worked for me here:
