Identify referenced users in posts via facebook api - facebook

I have an app, that makes requests to get posts from an specific page that i am administrator. But i want to store the facebook users that is referenced in each post published in the page wall. When I get each post I cannot find any field or anyway inside the text of the post to identify the people that is referenced.
Is this possible?
For more info, here is the reference to the FB documentation to request FB posts.
Thank you!

Found it! At the same get request of posts, you must add the field "message_tags"
An example:
http://fbapi_url/{post-id}?fields=message_tags,message,id,with_tags

Facebook Graph API unable to get comments from user's post

The Facebook Graph API seems no way to get any comments other than user itself posted from users' any Post, Album, Photo or Video nowadays. The /{object-id}/comments doc said A User can only query their own comments. Other users' comments are unavailable due to privacy concerns., also For the following nodes, the /comments endpoint returns empty data if you read it with a User access token:.
Does it really means Facebook Graph API unable to get user post's full comments in any way?
If this is for "personal use" your own user token then yeah you won't have a choice to bring anything else but if you're using a Page Token for a page that you manage then you can get the posts and comments but I'm currently unable to get the Comments "from" data so I can know who the User is (Name)

Tag persons in Facebook page post

I've written a Facebook web application, which is able to post links to the app page feed (as the page) by requesting the page token and doing a post request to the /PAGE_ID Graph REST endpoint. So far, so good, but I'd like to tag the links with their authors as well. When I add the tags parameter to this request with a value of my user id (I am an admin of the page), this works fine. But when I enter another user id (even one that likes the app page), no tagging is done. Does anyone have any experience with this? Some blog post suggest this is not possible using the Graph API, even though this is possible when done manually.
Thanks!
If I understand correctly what you want to do, it is no longer possible with the new version of the Facebook's API (v.2.0).

Facebook API for Share returning empty results set

I am new to Facebook API. I am building a Facebook app to fetch all the name of people who shared, commented and liked a post in a tabular format. I am able to get the like and comment details through Facebook API but can not find and proper API to get the share details.
I am using
https://graph.facebook.com/post_id?fields=sharedposts&access_token=my_access_token.
This API is returning an empty result set. And I have granted all the available permission to the access_tokn. Can anyone tell me ,Is there any other API that I can use. I saw a option of scraping the Facebook page for share,but I don't want to go that way because Facebook keeps on updating every thing.
I'm having the same problem as you, but I think I'm going a little step forward.
Try adding a limit to your sharedposts and maybe it will return some data:
Try this way:
https://graph.facebook.com/post_id/sharedposts?access_token=my_access_token&limit=1000
That should work for a regular post.
EDIT: Maybe the problem could be that althought you have granted all the perms to the token, the people who share that posts have to accept that permission too.
Otherway your JSON won't return any data.
The /sharedposts endpoint will -only- retrieve posts from users who have -also- granted your app. This means that even though a post might be public on a users' timeline, unless they have also granted your app permissions, you will not be able to retrieve that post.
For example: a user posted to a page and the post is public. This post can be retrieved with an access token. Let's assume that the user also shared this post to their own timeline. But, since the user has not granted permissions to your app, you will not be able to see this post using the /sharedposts edge on the original post (on the page). This also holds if the user shared their post publicly to his timeline.
This behaviour is by design; the API is more restrictive in returning user data than the website is. This holds for multiple endpoint and this is one of the examples where it is the case.

Facebook Graph Api json missing posts

I am developing an web app, which connect to facebook, to get posts, and other stuff liked by users. I have problem with getting all posts from user page using news feed(home connection of Grap API).
When getting access token in my app for user, I ask for read_stream, user_activities and offline access permissions. Then, when I use that token, to get json feed for
https://graph.facebook.com/me/home/?access_token=<retrived_access_token>
some posts(which are show on user page) are missing. I found that posts of my friends, which can be seen only by their friends, are not shown in that feed. The same issue is with posts of users which current I am subscribing.
I was searching on that for a while, and I found, that when I use link from http://developers.facebook.com/docs/reference/api/ to get my news feed, there are much more posts. It's seems to use a token generated for test console app for facebook api.
Then I tried to generate access token which would give me similar results using http://developers.facebook.com/tools/explorer?method=GET. But even when I give to generated token all possible permissions I could not get it working good, there were still some missing posts.
I read answer in that post, Facebook graph API does not return all posts for user, which suggested, that this is because of permissions set by my people who publish posts, who don't want their data to be retrieved by an app. I run some quick test, and I found that changing that setting is working( when somebody change that setting her posts will disappear from both feeds - that using my app token for user, and that under link on api reference page), but it's not the case.
It seems that this token generated on api reference page have an special permission.
I really need to get as much posts from user page as possible. I know that I will not get those blocked by their author, but as many of my users subscribe other users I really need to get access to kind of posts shown on user page.
I also read Facebook graph API: feeds missing in json response but it was also not helpfull.
I will really appreciate any help.
It is impossible to get a full list of posts from the feed / home Graph API, but you can use FQL to query the stream table to get almost every post made by friends, here is a quick example of how you would do that with the javascript sdk:
var query = 'SELECT post_id FROM stream WHERE filter_key = "others"';
FB.api('fql', {'q': query}, function(posts) { console.log(posts.data); });
This will get you the post ids, which you can then use with graph api to fetch the rest of the post info. Or you can get the full list of fields here, you can't select * in FQL so you'll have to list each piece you want and then get comments and likes and names separately.
There is an assigned/medium bug on this at http://developers.facebook.com/bugs/228057243915183. You can bump up the priority by subscribing and indicating you can reproduce it.
Also see http://developers.facebook.com/bugs/231621496918030 where Facebook has said "the stream table and me/graph have limitations. See the documentation for more info. We're trying to make this more clear in the future." Personally I don't think there is really any more info in the documentation though.

Graph API get information on facebook link shared

is that possible we can get the information from facebook API whether graph or REST or FQL regarding user sharing. Such as video or post or anything can share via facebook and it is shared by a list of user, with profile id or user name. I found something like this http://appshack.tv/2011/03/likes/ but it is just the counter, lack of information. Any way can do? Coz I found that facebook not stated everything in the documentation. Some trick is found from third party side.
No you can't get the user ids. Facebook will do their best NOT to share the user id with you "unless" they (the users) authorize your application.
And guess what....you can't even get the list of the users who are using YOUR application! (You can only get the count!)
