Previously - we were able to use the /account_id?acesss_token=APP_ACCESS_TOKEN to get the users information that authed in your app.
For the new v2.0 API, we get app_scoped_id where the folllowing method:
https://graph.facebook.com/v2.0/APP_SCOPED_ID?access_token=APP_ACCESS_TOKEN
Works for some users, but others - we get this:
{
"error": {
"message": "Unsupported get request. Please read the Graph API documentation at https://developers.facebook.com/docs/graph-api",
"type": "GraphMethodException",
"code": 100
}
}
Why would this function work for some users, but not others? We have no way to get the link property of the user to redirect them, nor does http:///facebook.com/SCOPED_APP_ID do anything or http://facebook.com/app_scoped_user_id/SCOPED_APP_ID work correctly. Anyone have advice to redirect the user to their FB profile via the FB Scope App ID?

My Facebook page publishes public events and I am developing an app that uses this page. I want to get the number of interested/going people for a specific event given its Facebook id.
I, the creator of the app, am also the admin of the page. However, using my app access token that I generated with the app id and the app secret, I can't call the event API: https://graph.facebook.com/v3.0/137340177139954?access_token={access_token}
I get the following error
{
"error": {
"message": "Unsupported get request. Object with ID '137340177139954' does not exist, cannot be loaded due to missing permissions, or does not support this operation. Please read the Graph API documentation at https://developers.facebook.com/docs/graph-api",
"type": "GraphMethodException",
"code": 100,
"error_subcode": 33,
"fbtrace_id": "FqJ5oAqdukA"
}
}
What am I doing wrong? How do I get event information about a page that I own
The endpoint that you're hitting is not correct. You're forgetting the /events portion after your page_id.
This is what it should look like:
https://graph.facebook.com/v3.0/137340177139954/events?access_token={access_token}
I am having a problem with the facebook graph API, when I try to read a Page feed using graph../{pageId}/feed it works only for some pages. On other pages I get the following error:
{
"error": {
"message": "(#200) Requires extended permission: ads_management or manage_pages",
"type": "OAuthException",
"code": 200
}
}
The Page is restricted by location, as we found out in the comments. If it works for one user, most likely the other one is not allowed to view the page - which means that you can´t grab the feed with his User Token. The Page could also be unpublished, but i guess that´s not the case.
If you are unsure, try lifting the restriction and test it.
If that does not work, you should file a bug.
I am having some unusual errors while fetching some data for some users via graph API.
As for example w all know we can get basic user info via graph.facebook.com/username
And it works. But it is not working for some users. Like the user www.facebook.com/sanzida.tanzum is a valid facebook user. So, we should get her basic info via graph.facebook.com/sanzida.tanzum. But when you will try that, you will get the error
{
"error": {
"message": "Unsupported get request.",
"type": "GraphMethodException",
"code": 100
}
}
And it is not a permission issue because use user herself gets the same error when she try to retrive her own data via graph API. Actually the user sanzida.tanzum is invisible to graph API. For example user sanzida.tanzum is on my friend list. You can check here. my friendlist.(it is public). But when I retrive my friendlist via graph API, my friendlist is shown excluding the user sanzida.tanzum ! But she is in my friendlist!
I have tried to contact facebook for this matter because I did not find any doccument related to this matter. They replied it is usual. (probably they did not read my mail at all. I am including the email conversation with facebook)
Hi তৌফিক,
They are getting errors because they are not you... they dont have
permissions to see the same things you do. They might also be missing
an access token. Either way: no bug here.
Thanks,

Your Email Address: *****#ovi.com Do you have technical details of
a security vulnerability?: Yes Vulnerability Type: Privacy /
Authentication Vulnerability Scope: Platform Developer API Title:
Unusual bug in facebook graph API Product / URL:
https://graph.facebook.com/sanzida.tanzum Description and Impact: I
was doing some graph API calls for testing purpose. Mostly I was doing
mostly user profile calls. (https://graph.facebook.com/exampleuser)
Somehow I realized facebook is giving following errors for some users
even they are on my friendlist. Same thing occurs when they try by
themselves.
As for eample the user "https://www.facebook.com/sanzida.tanzum" is on
my friendlist. (My friendlist is public.You can check if you want.)
So, according to facebook graph API, I can request the user's basic
info using (https://graph.facebook.com/sanzida.tanzum) But it returns
this error:
"{ "error": {
"message": "Unsupported get request.",
"type": "GraphMethodException",
"code": 100 } }"
Actually graph API can't access nothing of this user. Another
example.. When I request my friendlist via graph API , All friends of
my friendlist is shown except the user (sanzida.tanzum). But she is in
my friendlist! check here (my friendlist is public)
"https://www.facebook.com/toufiqueimam/friends". So why is this
happening only for few users?
Just now I got confirmation that the user herself gets the same error
if she tries to access (https://graph.facebook.com/sanzida.tanzum)
{ "error": {
"message": "Unsupported get request.",
"type": "GraphMethodException",
"code": 100 } }
Reproduction Instructions / Proof of Concept: Reproduction: first go
to https://www.facebook.com/sanzida.tanzum You will see it is a valid
profile. Now try https://graph.facebook.com/sanzida.tanzum You will
get following error
{ "error": {
"message": "Unsupported get request.",
"type": "GraphMethodException",
"code": 100 } }
This isn't a bug, the error means that the data you're trying to access is not accessible to you, does not exist, has been deleted, is not available because you haven't provided an access token from a user who can see it, etc.
See this answer for an example of this error message in relation to Facebook pages: https://stackoverflow.com/a/6847088/21062 - the same is true when trying to access user profiles if that user has blocked you, blocked your app, disabled their account or disabled all apps from accessing their information.
Just an FYI, I ran into this problem, and it wasn't because the user had blocked all applications. In my scenario, my application was attempting to force-convert Facebook's 64 bit integers into a 53 bit JavaScript integer (Node application). It was mangling the value, so when I was making the Facebook GET Request later on in my application lifecycle, I was doing so with the mangled value, and Facebook was trying to tell me "Um, this UserId doesn't exist".
So in my application, I had to use the Node Big-integer add-on, along with the Mongoose mongoose-long plugin for my Mongodb.
Long story short, if you are converting the UserId to it's native 64 bit integer, don't do so unless the intger type in your application is at least 64 bits.
I try to retrieve post's information from Graph API:
https://graph.facebook.com/100006679472813_1392957120936924?access_token={my_access_token}
The Facebook Graph response:
{
"error": {
"message": "Unsupported get request.",
"type": "GraphMethodException",
"code": 100
}
}
However, I can access the post by this link (same user as {my_access_token}) https://www.facebook.com/100006679472813_1392957120936924
And I can receive the original message of this post via Graph Search API too.
Not all posts return error. But so many do. How can I get it's detail via Graph API?
You can not read all the posts in the facebook. If you try to fetch the details of the post by the user other than the user in the session, you may or may not get the details of the post. This depends on the privacy settings of the user. So, only the public posts can be fetched (in case of other users)
I am trying to fetch a Facebook page's events. I have before, but it doesnt work any more. I used this scriptto fetch the events.
$string = file_get_contents("https://graph.facebook.com/?$pageids&fields=events.limit($fblimit)&access_token=$token&method=GET");
$json_a=json_decode($string,true);
$pageids was a lot of different facebook ids (id1,id2,id2 ...)
I get this error message:
{
"error": {
"message": "(#100) Unknown fields: events.",
"type": "OAuthException",
"code": 100
}
}
Does anyone know what is wrong with my script? Is there a another way to fetch Facebook events?
The actual URL to get a page's events is something like this :
https://graph.facebook.com/PAGE_ID/events
I'm not sure how old the code is that you are fixing, but this is the correct method as stated in the documentation. events is a connection of the page object.
Reference: https://developers.facebook.com/docs/reference/api/page/#connections
Facebook has had restricted access of Events in API recently.
You have to do app review to have access to Pages API, Events API.
