Since Facebook's Graph API changed to version 2.4, I find that any query attempting to retrieve posts made returns an error:
type: OAuthException, code: 1, message: An unknown error has occurred. [HTTP 500]
My request code uses Facebook's koala ruby api to make requests:
posts = #graph.get_object(appid+"/posts?limit=20",api_version: "v2.3")
I added the version count now, based on koala's recommendation, but the result for this is still the same error that I got without specifying the version. My access token is definitely valid, does anyone know if something else has changed or if this is a bug?
Extending #Tobi 's comment. You have to pass a page/event/user/group id to retrieve the post.
Also, you've to explicitly pass fields parameter to query additional data of a post. So your query will become:
posts = #graph.get_object(id+"/posts?fields=id,name,message,picture&limit=20",api_version: "v2.4")
Please refer to this document of Facebook Developers to learn more about /postsedge.

I am trying to retrieve Store Visits data from the Facebook Insights API. Based on their documentation, these should be available by specifying the following parameters:
store_visit_actions
cost_per_store_visit_actions
When I use store_visit_actions as a parameter, no data is returned. I know data exists because it is displayed through their UI reporting tool.
When I use cost_per_store_visit_actions, I receive a 100 invalid param error:
cost_per_store_visit_actions is not valid for fields param.
These params are listed as "In Development", however, I'm retrieving other development parameters without issue. Is anyone facing the same issue or know how to fix?
this is because the metrics
store_visit_actions
cost_per_store_visit_actions
are deprecated in facebook api v11.0. You can checkout this link:
https://developers.facebook.com/docs/graph-api/changelog/version11.0/
I am trying to access campaigns of the facebook account. Using python lib: https://github.com/facebook/facebook-python-ads-sdk
Receive error: (#100) Tried accessing nonexisting field (campaigns) on node type (AdAccount)
Url: https://graph.facebook.com/v2.11/{account_id}/campaigns
Everything worked fine for months. Now, even facebook page for this url is empty: https://developers.facebook.com/docs/marketing-api/reference/ad-account/campaigns/
Any thoughts, what's the problem?
Seems to be a bug.
Reported here: https://developers.facebook.com/bugs/707332642990208/
Works perfectly without time_range param.
So, could be temporary solution.
I don't know if this is a bug or not: facebook does this from time to time and is implementing check routines for parameters - in fact "adaccounts don't have any parameters:facebook api reference adaccount reading)
The error you are getting (#100) says "invalid parameter" (facebook reference adaccount validation rules), this is, because you may have defined the time_range and you are asking api for campaigns in an adaccount. But: for adaccount edge time_rage parameter is invalid.
The solution is to FIRST asking api for https://graph.facebook.com/v2.11/{account_id}/campaigns and after this defining the (time_range) parameter(s) for the insights of your campaign.
I tried to get Data from Facebook Page with the graph of Facebook but I have a problem.
When I try to go on link like:
https://graph.facebook.com/ID-PAGE?access_token=MY_ACCESS_TOKEN
I always do this to have the Data from a Page but since today I have the error Message: "An unknown error has occurred".
Thanks for help.
EDIT:
The bug is fixed : https://developers.facebook.com/bugs/486654544831076/?search_id
Have a look at my answer at
How to get user email and birthday from Facebook API Version v2.4
You have to specify each field you want to query now with v2.4. If you want to explicitly use v2.3, you need to prepend your calls by /v2.3 like this:
/v2.3/{page_id}?access_token=MY_ACCESS_TOKEN
Seems like there's currently a bug regarding requests made with app access tokens instead of user access tokens:
https://developers.facebook.com/bugs/486654544831076/
At this moment, I pretty much figured out what is happening, and it looks like a bug in the Facebook API.
For v2.3 and lower:
The /PAGE-ID call will return an Unknown server error when you don't pass ?fields=username (for example). If you do pass the fields option, it will work. You can get it out of the docs.
For v2.4:
This will work, but you will miss a lot of data, so you'll also have to pass the fields options. But if you don't pass that, this version will give you back only the most basic of details. This is as described in the version release: https://developers.facebook.com/blog/post/2015/07/08/graph-api-v2.4/
So the solution for now, would be to add the ?fields= everywhere you need, or to wait for Facebook to maybe ever solve it.
(And while you're at it, you might as well upgrade to v2.4 ;-)
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 looking for a list of all Facebook can return when you try to fetch infos using Graph API. Can anyone help?
Facebook returns a 400 HTTP error, and a JSON content like:
{
"error": {
"type": "OAuthException",
"message": "Invalid OAuth access token signature."
}
}
I'm searching the different returns of the same kind it is possible to get.
Facebook used to have this published somewhere, but for whatever reason it was removed. But you can find the full list here:
http://www.takwing.idv.hk/tech/fb_dev/faq/general/gen_10.html
There seems to be a list now for the errors.
I posted answer for the same question here: Facebook Graph API error code list
(I found the list here https://developers.facebook.com/docs/graph-api/using-graph-api/error-handling)
In case Takwing's copy ever comes down, here's another copy: http://fbdevwiki.com/wiki/Error_codes
These codes were primarily for the REST API, but they do also come up with the Graph API. Some of the Graph API calls have underlying FQL calls that return the FQL error codes. And the direct FQL queries are still part of the currently accepted API.
Update: I'm trying to keep this list up-to-date. Please feel free to make changes as you encounter new errors.
I am trying to keep an updated list of error codes based on previous outdated information.
You can find the repo here http://github.com/phwd/fbec and it has been updated with Test User and Credit Error codes from the Facebook Documentation.
Currently looking for the constant name for "Error Code 2500" and some error descriptions may have changed. I hope to keep on top of this.
There is an official error code page, now:
https://developers.facebook.com/docs/marketing-api/error-reference/
It still doesn't look comprehensive...
