I've created a page on Facebook without creating an account. This means that a default account is created with the page_id the same as the account_id.
When I try and perform a graph call to the tabs on the page:
/<page_id>/tabs?auth_token=<auth token>
I get an empty "data" representation:
{
"data": [
]
}
Even though there are application tabs installed.
Add the tab_id makes no difference, I get the same response.
I'm guessing the page is getting confused as the account but I cannot find any way to distinguish the difference between the account and the page.
Does anyone know if it is possible to retrieve the page information another way?
Double-check that the access token you're using is the Page Access Token - this is the most likely reason this will fail to return an answer

I have been hammering away at this problem for the last day. I really hope someone can help me out. I would be very grateful.
What I am trying to do is fetch event data from a Facebook Page. I looked over the documentation, which says this about reading Pages data:
Reading
A Facebook page
Permissions
For pages that are published, you need:
An app or user access token to view fields from fully public pages.
So what I did was I obtained an app access token via:
GET https://graph.facebook.com/oauth/access_token?
client_id=YOUR_APP_ID
&client_secret=YOUR_APP_SECRET
&grant_type=client_credentials
which then returned
access_token=MY_APP_ID|MY_APP_ACCESS_TOKEN
After this I followed the documentation and made the following call
https://graph.facebook.com/v2.4/129511477069092/events?fields=id,cover,name,venue,description&access_token=MY_APP_ID|MY_APP_ACCESS_TOKEN
This returned:
{
"data": [
]
}
So after some fiddling around I was able to make the call by switching to version V2.2 and by creating an access key with Facebook API Graph explorer tool(no permissions granted).
GET https://graph.facebook.com/v2.2/129511477069092/events?
fields=id,cover,name,venue,description&
access_token=ACCESS_TOKEN_FROM_FACEBOOK_API_EXPLORER_TOOL
The page I am trying to retrieve data from is public and so are the events, so I can't figure out what is going on. I know I am super close since I am able to retrieve the data with the token provided by the Facebook API Graph Explorer Tool. The thing with using this token is that it only last a few hours and I need something that is going to last longer such as an app access token. I have done some research on Stackoverflow and found similar questions, but none of them solve my problem. Any help will be appreciated to the max! Thanks.
Looks like a bug of v2.4 to me. It works with v2.3 if you remove the deprecated venue field:
https://developers.facebook.com/tools/explorer/145634995501895/?method=GET&path=129511477069092%2Fevents%3Ffields%3Did%2Ccover%2Cname%2Cdescription&version=v2.3
If the version is changed to v2.4, it returns an empty result.
https://developers.facebook.com/tools/explorer/145634995501895/?method=GET&path=129511477069092%2Fevents%3Ffields%3Did%2Ccover%2Cname%2Cdescription&version=v2.4
There's no documentation about this in the changelog at
https://developers.facebook.com/docs/apps/changelog#v2_4
so I guess it's a bug. There's already a bug report at
https://developers.facebook.com/bugs/443054055873667/
with status assigned. If you have an app that supports v2.3, I'd suggest you prefix your request like this:
GET /v2.3/129511477069092/events?fields=id,cover,name,description
I'm creating a custom module in Drupal, that for part of its functionality must fetch posts from a business page. So for simplicity, I'm using fbapp module as a dependency (drupal.org/project/fbapp), so that I can use it's authentication and request functions (fbapp_app_authenticate() and fbapp_graph_request()) without having to worry about the constant facebook graph updates making my own code obsolete.
I've created a facebook app, so authentication should be app token, using appid and app secret. This seems fine and I'm getting back access_token. However, when I try to read posts from a publicly available page (the clients), I get the response:
"Unsupported get request. Please read the Graph API documentation at https:\/\/developers.facebook.com\/docs\/graph-api"
Here's the queries and responses my code produces:
graph.facebook.com/oauth/access_token?client_id=<redacted>&client_secret=<redacted>&grant_type=client_credentials
array(1) {
["access_token"]=>
string(43) "<redacted>|<redacted>"
}
graph.facebook.com/<page_id>/posts?access_token=<redacted>|<redacted>"
string(183) "{"error":{"message":"Unsupported get request. Please read the Graph API documentation at https:\/\/developers.facebook.com\/docs\/graph-api","type":"GraphMethodException","code":100}}"
Can anyone verify a correct way to query a Facebook page programmatically, perhaps there's a setting in the page I'm querying that I need to set (although I can't find anything)?
If page restrictions apply, the page's feed can only be retrieved with an user access token as far as I know (because FB needs to evaluate the visibility criteria, and setting your app to the same restrictions doesn't help here):
See
https://developers.facebook.com/docs/graph-api/reference/v2.4/page/feed#readperms
It looks like everything you have done is correct. The response you got can be (i am not sure) because you got your clients pageid wrong.
So recently there was a update to the Facebook Graph API and now pretty much everything requires a access_token to retrieve any type of data.
Previously you could get the number of page likes by accessing the graph like so:
http://graph.facebook.com/{page-name}
But now if you try it says you need to have a access token because of a recent update to the API. Now the issue i am having is i cant access the likes even with an access token this is the response i am getting:
Request
http://graph.facebook.com/{page-name}/?access_token={access_token}
Response
array(2) {
["name"] "Page Name"
["id"] "Page Id"
}
Now at first i thought the access token wasn't being generated with the correct scopes but i am 99% sure you only need read_stream to pull that type of data.
Second thought is that they have removed the ability to acces likes of any page and you need a page token to receive that type of data or finally i am missing something incredibly small here and its still achievable?
So my question is can you still get the number of likes of any page using the Facebook Graph API and if the answer is yes how do you do it?
any help appreciated
This can help you! Just add ?fields=likes after the page name/id. You can use any access token for fetching data!
graph.facebook.com/{page_name}?fields=likes&access_token={token}
The Graph API v2.4 reduces the number of fields in default responses.
https://developers.facebook.com/blog/post/2015/07/08/graph-api-v2.4/
Fewer default fields for faster performance: To help improve performance on mobile network connections, we've reduced the number of fields that the API returns by default. You should now use the ?fields=field1,field2 syntax to declare all the fields you want the API to return.
If you do ?fields=likes it should show up.
You can do like this:
https://graph.facebook.com/v2.4/{page_id}/fields=likes
Anybody knows why i get no results back when i add the untill parameter in facebook?
Requested url: https://graph.facebook.com/FBID/home?limit=25&until=1388688636
How do i replicate this:
Go to: https://developers.facebook.com/tools/explorer
Execute the above url (FBID/home?limit=25&until=1388688636)
In the returned results go to the bottom and click the link that got the json key: "next" (looks like: "next": "https://graph.facebook.com/FBID/home?limit=25&until=1388688639")
The returned result is:
{
"data": [
]
}
i searched for ages about this problem and could not find it, the only thing i can come up with is that Facebook only returns posts since the permission accept for the Access Token, another cause could be that Facebook is broken.
This is standard (albeit undocumented) behavior. The empty data array shows up when you try to access an object that has its privacy settings configured to not let third party apps read it, and it's also what's being displayed after you've reached the end of all public records of the current user.
You just have to deal with it. Keep looping over the next result while data != empty is true.
Update: This could also be related to an open issue Facebook is aware about, namely broken pagination. The problem seems to be "dead ends". You can read more about it here and try fiddling around with the timestamp and limit parameters of the request.
I've been messing around with the graph API and have been able to access my own information just fine. However, when I attempt something like:
https://graph.facebook.com/999999/likes?access_token=xxx (where 999999 is a friend's ID)
I get a blank graph like so:
{
"data": [
]
}
Keep in mind I'm doing this all manually for the time being. This is the URL I used to request permission from my profile:
https://www.facebook.com/dialog/oauth?client_id=xxx&redirect_uri=http://www.google.com&scope=email,read_stream,offline_access,user_likes,friends_likes
It all works hunky-dory and I get my access code, yet I still receive the blank graph. Suggestions?
Thanks.
Have you tried multiple friends? Your friends can configure what information third party applications can have access to, of theirs. For example I could limit applications that you use to not see anything about me, if we were friends.
Also you could check in account --> privacy --> settings --> applications and see if your application in fact has the permissions you think you granted it as a user.

I agree with kevin. You need to request permissions first to get at the info and you also need to be prepared that you will get a blank list.
I suggest that you use an already built api as it will save you a lot of time. I've recently released one here that should get you going in no time at all.
The code looks like this:
Dim FB As New SessionInfo("[access_token]")
Dim Req = New Functions.Requests(FB)
Dim U = Req.GetUserInfo("[userid for friend]")
Response.Write(U.name)
Also you can get a list of friends by calling this
Dim FL = Req.GetFriends()
For Each F In FL
Response.Write(F.name)
Next
I have come to notice that even though an application can request (and be granted) certain permissions, e.g. to access Likes, it doesn't necessarily mean that an application will be able to access this information.
I'm not a 100% certain of this but there might be two instances where e.g. requesting a users Likes results in an empty data set even though the right permissions where requested and granted by the user:
The user has set custom permissions in his/her privacy settings
not make public the information (e.g. Likes). Basically, customized
permission settings overrule the granted permissions that an
application requested.
The user is under 18. https://www.facebook.com/help/?page=214189648617074
