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.
Please check section "Apps that Require App Review, Business Verification, and Supplemental Terms" of this url: https://developers.facebook.com/docs/apps/review

I have an element on my website which shows facebook posts from a page and the amount of views/likes/comments. This stopped working all of a sudden and I have no idea why.
If I make the request with the graph api tester tool I get:
{
"error": {
"message": "An unknown error has occurred.",
"type": "OAuthException",
"code": 1,
"fbtrace_id": "CIHVxFhXIv/"
}
}
This is the request link I use with file_get_contents:
https://graph.facebook.com/v3.0/idofmypage/posts?fields=comments,full_picture,likes,message,picture,story,permalink_url,updated_time,from,insights.metric(post_impressions)&access_token=myaccesstoken
Did something change again with permissions or maybe a field is deprecated?
According to this fb new the Pages API and others have changed, and now you can only access the data if it's a page of your own.
Pages API: Until today, any app could use the Pages API to read posts or comments from any Page. This let developers create tools for Page owners to help them do things like schedule posts and reply to comments or messages. But it also let apps access more data than necessary. We want to make sure Page information is only available to apps providing useful services to our community. So starting today, all future access to the Pages API will need to be approved by Facebook.
Today I've started a project wich, in the begging, I need to recollect data and that's what I've found about it..
Facebook's Graph API documentation lists the application object's ios_bundle_id field under the "Updating" section. However, sending a POST request to update said field, e.g.
POST: https://graph.facebook.com/v2.3/{application_id}?ios_bundle_id=["com.Company.AppName"]&access_token={app_access_token}
Responds with this error message:
{
"error": {
"message": "(#100) ios_bundle_id cannot be edited using the API. Please use the Developer App to edit settings instead.",
"type": "OAuthException",
"code": 100
}
}
I am able to update this field through the Developer App page, but in my case, I need to update this field programmatically.
I have successfully tested that same POST request to update other fields, e.g. app_name, so I am certain the request is structured properly.
Has anyone encountered this issue, or similar? Any suggestions are appreciated.
This is a documentation error. This field is not editable via the Graph API. You have to go into your Facebook Application Dashboard and change it from there.
Here's a link to the bug report created to fix this:
https://developers.facebook.com/bugs/1646835812217089/
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 created and APP on the Facebook.
Now I am trying to post a comment on the user's timeline using the Graph API but I cannot undestand what I need to do.
I already authorized the Application (I authorized this permissions: 'user_status,publish_stream,user_photos,email').
If I look on my profile -> privacy I can see that the APP can:
This app can: Post on your behalf
This app may post on your behalf, including status updates, photos and more.
Last data access:
Basic InformationToday
See details · Learn more
Posts on your behalf:
Who can see posts this app makes for you on your Facebook timeline?
Public
Notifications:
When to notify you?
The app sends you a notification
So this part seems OK.
On my application I do the following to try to post somenthing on my timeline (I need to post it when I am off line).
1) GET : https://graph.facebook.com/oauth/access_token?client_id=APPID&client_secret=*APP_SECRET*&grant_type=client_credentials
RESPONSE:
access_token = 422828347771671|UdQELQIf0N7krF4JUo7VwtPLTkk
2) GET: https://graph.facebook.com/search?q=myemail&type=user
RESPONSE:
_"error":_{
______"message":_"A_user_access_token_is_required_to_request_this_resource_",
______"type":_"OAuthException",
______"code":_102
___}
But reading the documentation (https://developers.facebook.com/docs/reference/api/#searching) it seems that this request does not need any kind of access token.
I also tried to add the access token, but the result is still the same.
3) I know my facebookid so I tried to use it directly:
POST: https://graph.facebook.com/100001139132403/feed
ARGUMENT:
access_token=422828347771671|UdQELQIf0N7krF4JUo7VwtPLTkk,
message=Hello
RESPONSE:
"error": {
"message": "(#200) This API call requires a valid app_id.",
"type": "OAuthException",
"code": 200
}
}
So I tried to add client_id=APPID and app_id=APPID, I tried to put one, the other and also both arguments as GET or POST but nothing changed.
I checked the APPId ad it is correct.
Do someone have any idea?
Thank you!
You cant simply generate a user access_token by querying to a URL. What you did gives the App access token and as the error say, you are trying to do something, that needs user access_token.
Refer and implement this : https://developers.facebook.com/docs/howtos/login/server-side-login/
And use that access_token for the rest of the processes.
Yesterday I started a new app on Facebook. Today I got the message that when people copy the link to Twitter they get an error. This is what you get:
{
"error": {
"message": "Unknown path components: /your_namespace:your_action",
"type": "OAuthException",
"code": 2500
}
}
What does this mean? What could be the problem?
Are you actually sending the POST action link to Twitter? Why?
I think you misunderstood how Open Graph works. Basically, you should be the one publishing actions when users take an action using your service. You can use a server-side or a client-side language to POST request (when you click a link, your browser actually makes a GET request, not a POST) to https://graph.facebook.com/me/namespace:action?access_token=ACCESS_TOKEN&OBJECT_PATH=OBJECT_URL
Note that you need to create an app, use it to authenticate users to get the access token and also set your custom actions / objects. These will need to be approved before you can actually use them.
You should start by taking a look at the sample apps to see how they work: https://developers.facebook.com/docs/samples/
