I am developping my first facebook social game in PHP and I follow the social game tutorial provided on developer.facebook.com
My game is on a server and loaded into a canvas page.
Everything is clear but I can't resolve a problem when I try to deal with achievements: http://developers.facebook.com/docs/guides/games/getting-started/#step6
I was able to create, register and save achievements but I get an error when I try to consult the achievements my user had already earned. The code is this one:
function getAchievements() {
FB.api('/me/achievements', function(response) {
for(var i = 0; i < response.data.length; i++) {
...
}
...
});
In my console, if I trace the response object, I see there is an authentication error:
response : {
"error": {
"message": "An active access token must be used to query information about the current user.",
"type": "OAuthException",
"code": 2500
}
}
I've tried a lot of things but I can't resolve this problem.
The user is logged, I've asked for email,publish_actions permissions, I've tried to add the user_games_activity extended permission... :(
Does someone know what is going on with this particular FB.api call?

our web application posts messages to Facebook wall of logged user. We are using the Facebook Graph API. This feature did work in the past. When trying it today, I am getting an error message and cannot figure out where the problem is.
I am testing it with my Facebook account and I did not reject any permission.
When the user wants to connect his / her FB account with our web app, the app redirects to
https://www.facebook.com/dialog/oauth/?client_id=our_ID&redirect_uri=our_URI&state=generated_string&scope=email,publish_actions&response_type=code
Later, when the app calls
https://graph.facebook.com/me/permissions?access_token=some_token
it receives response
{
"data":[
{
"permission":"email",
"status":"granted"
},
{
"permission":"public_profile",
"status":"granted"
},
{
"permission":"installed",
"status":"granted"
}
]
}
The permission publish_actions is missing.
When the app POSTs to
https://graph.facebook.com/me/feed?access_token=some_token
with parameter
message=somemessage
the following error response is returned
{
"error":
{
"message":"(#200) The user hasn't authorized the application to perform this action",
"type":"OAuthException",
"code":200,
"fbtrace_id":"FDM+n+5S14V"
}
}
Why is the permission to post on wall suddenly not granted?
Thanks for help.
I am using facebook Graph API to get user data with the below query
https://graph.facebook.com/search?q=xxx yyy zzzz&type=user&access_token=myTokenHere
And the reply is;
{
"error": {
"message": "(#9) Access denied",
"type": "OAuthException",
"code": 9
}
}
And also it makes my account to logoff from developer.facebook.com. When I try refreshing that web site it says I am logged out.
I am used to use this account for making this search, this happened suddenly. I made maybe a thousand successful search with this link, with this user with this query.
It doesn't says I am limited or something.
I googled it a lot and made a lot of research but couldn't find any solution to it.
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,

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'm following the documentation here:
https://developers.facebook.com/docs/opengraph/using-object-api/
Using the following:
/me/objects/<app-namespace>:<created-object>?privacy={"value":"SELF"}
&object={"image":"https://<image-url>"}&access_token=<user-token>
Testing with the Graph API tool i'm getting this error:
{
"error": {
"message": "(#200) Requires extended permission: publish_actions",
"type": "OAuthException",
"code": 200
}
}
Ok well that seems obvious until I debug the access token:
Valid True
Origin Mobile Web Faceweb
Scopes publish_actions, user_friends
Anyone else seen this or have an idea of how to fix it?
EDIT Ok so I had publish_actions in both User & Friends and Extended permissions. I removed the User & Friends permission and now I get this:
{
"error": {
"message": "An unknown error has occurred.",
"type": "OAuthException",
"code": 1
}
}
Me no like unknown.
Ok so a couple things to note here that went wrong.
I picked an object type as an item thinking it would be <myapp>:item in the call. Well as it turns out the item is actually a product type so it is product.item a global type. What is handy is to actually click the get code link on the objects you create. Solution was to actually create my own app object type, which I thought I had.
In the Graph API make sure you actually use the application pull down in the top right to select the right app. I noticed some issues when it was set to the generic Graph API Explorer app.
Silly mistakes but cost me some time, hope it helps someone else.
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.
