So I have been watching some tutorials about the facebook graph API, and one of the things in the video is to simply navigate to http://graph.facebook.com/youtube
and it should display a json response of their facebook likes etc. This is said to work without an access token?
But this doesn't seem to work, i get the following response -
{
"error": {
"message": "An access token is required to request this resource.",
"type": "OAuthException",
"code": 104,
"fbtrace_id": "DoY144sSuti"
}
}
Has something changed that you will need to always need an access token just to see peoples data, eg how many likes a page has?

Yes. Since API v2.0, all API calls (with the profile picture redirect being the exception) need to use an access token.
Public data about public pages can be accessed using an app access token; if the page is not public it needs a user access token for a user that can see the page, or a page access token. (More about the different types of token here: https://developers.facebook.com/docs/facebook-login/access-tokens)

Then that tutorial is simply outdated.
Yes you will need the access token in order to view that Jason data in URL .
try this Instead :
https://graph.facebook.com/page-id/posts?access_token={your-access- token}
You will be able to see the posts now.Hope this would help you .

I would like to find the id (app-scoped) for someone who has posted a comment on a public page.
For example, I get a list of recent posts/comments on the NY Times page via:
v2.11/nytimes/feed?fields=comments.limit(10){message,created_time,from},name,message,from&limit=2
The data returned looks like this:
"comments": {
"data": [
{
"message": "Wouldn’t know. Not paying $13/mo for this.",
"created_time": "2017-12-10T05:57:18+0000",
"id": "10151412260164999_10151414049324999"
}
],
There is no from field. The same is also true if I attempt to view the comment directly using it's id with
v2.11/10151412260164999_10151414049324999?fields=from,message,created_time
I have tried using the Facebook Graph API Explorer, using both my User Token, as well as an App Token.
Since v2.11 of the Graph API, you need a Page Token to get user data of comments: https://developers.facebook.com/docs/graph-api/changelog/version2.11#gapi-90
User information will not be included in GET responses for any objects owned by (on) a Page unless the request is made with a Page access token. This affects all nodes and edges that return data for objects owned by a Page.
In other words: You can only get user information if you manage the Page.
Edit: Since the latests update in the Graph API, you have to get the App reviewed and you must go through Business Verification or Individual Verification. (thanx #Guiman04)
Please check whether you are using the accessToken for the page you are trying to get data from, i had same issue, and was resolved by using the correct accessToken for the page.
I am running queries against Facebook Graph API to fetch OG meta information about URLs. Using a Facebook APP token, I can request most URLs and get their corresponding meta data back. But I have run into two issues that I can't find a solution for. I have one domain that refuses to pull any meta information using an APP token. Instead I get back an error 100 (Unsupported post request). But when I make the same request using a User Access Token, it works correctly. The second issue I found is that when a URL has any kind of OG error, Facebook is still scraping it, but will return a 100 error instead of returning the meta details (with both the app token and the user access token). I've even tried running the query without the scrape parameter, to no avail.
Normal Request That Returns Meta Fields of URL:
POST:
https://graph.facebook.com/v2.9/
{
"id": "http://viralcrunch.com/articles/22325/these-guys-invented-the-anti-smart-phone-and-it-will-blow-your-mind",
"scrape": "true"
}
Request That Returns 100 Unsupported post request Error W/ App Token
POST:
https://graph.facebook.com/v2.9/
{
"id": "http://turnthispage.com/dads-totally-winning-fatherhood/",
"scrape": "true"
}
Request That Returns 100 Invalid Object Error W/ Any Token
POST:
https://graph.facebook.com/v2.9/
{
"id": "http://www.thesportster.com/basketball/top-20-nba-players-who-live-life-to-the-fullest/",
"scrape": "true"
}
The second URL seems to be associated with an app id of an app that has some kind of access restrictions set; so I guess it is the same here as if you tried to access information about a Facebook Page that has access restrictions set - you can not query any details about those using the app access token, you need to use a user access token for a user that is allowed to see the content, or a page access token for that page.
And that you get an error response for the third one seems only natural. After all, this is a tool intended to debug and scrape the Open Graph objects you are in control of, so if the OG meta data is not in order it should return an error.
Facebook has some great-looking examples of Open Graph requests here:
https://developers.facebook.com/docs/reference/api/examples/
The problem is that since I don't have an access token, most of the examples just return
{
"error": {
"message": "An active access token must be used to query information about the current user.",
"type": "OAuthException",
"code": 2500
}
}
I understand access tokens, but how do I get the token so that I can experiment with these example requests?
As long as you only want to test...
Use the Graph API Explorer to generate a token with the permissions you want.
Don't hesitate to select all of them.
Then, just copy/paste the token at the end of each graph.facebook.com URL. For instance:
https://graph.facebook.com/v1.0/me/friends?access_token=<ACCESS_TOKEN>
The day you want to get the access taken for an app...
Start by reading this doc.
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.
I'm currently working on a facebook app which captures wall posts for a specified user, page or group, after a user has authorized the app I quote the access_token that is returned to call the method
https://graph.facebook.com//feed?access_token=
this works fine for pages and groups as we only need a valid token, however for users the results are different depending on the relationship between the user who authorized the app the user whose posts are being captured.
For example if there is no relationship between the two users some posts are not returned even though they are public and displayed when you view the profile of the user, however if they are friends more posts are returned.
Can someone please explain this behaviour? And is it possible to obtain all posts using this method?
Yes, per the permissions listed at https://developers.facebook.com/docs/reference/api/permissions the results of the call are different depending upon the relationship.
However when things are public and you use an access token that doesn't belong to the user, then no results are returned. I cannot remember a time when this wasn't this way. For some odd reason (by design or omission on Facebook's part) using the graph API to get at public posts using a user access token just doesn't want to work.
For example, You can see some public items here
http://www.facebook.com/zuck
http://graph.facebook.com/zuck
However, you cannot seem to get any feed from here without an access token
https://graph.facebook.com/zuck/feed
{
"error": {
"message": "An access token is required to request this resource.",
"type": "OAuthException"
}
}
Let's try adding an user access token that does not belong to zuck or a friend of zuck. https://graph.facebook.com/zuck/feed?access_token={UserAccessToken}
And here's what we get:
{
"data": [
]
}
What about an app access token? Let's try
https://graph.facebook.com/zuck/feed?access_token={AppAccessToken}
{
"error": {
"message": "Invalid OAuth access token signature.",
"type": "OAuthException"
}
}
So as you can see, it's difficult to get things via the graph that are not in alignment with your access token.
I manage to get most of the feeds from user's wall post. Although this is a old post, I hope someone can manage to get what they want from my answer.
Before getting the access token(to get the feeds), you need to add multiple correct Read Permissions "keys".
For example, you will have to add "read_stream", and "user_status" (which I found that these are the most important permission "key" to generate the correct access token, to retrieve one's so-called "public" feeds).
You can add more into generating the access token, in either you want the permission to GET, or POST, or BOTH.
Source is here: https://developers.facebook.com/docs/howtos/ios-6/#nativeauthdialog
One thing that I found is, the way to get the feeds result from user's "Home/About" page and Facebook Page (which is created for people to like (not add friends)) are different. The key is mentioned above, "read_stream", and "user_status". So it's better that you add both of the permissions in order to generate the access token to get everything in feeds.
Graph API doesn't return posts to the App if is not authorized to read user feed, even if posts are public.

According to the latest api ,
FB.api("/me/feed","get",function(response) {//callback})
should do and also work well .
It is working now but facebook may change it in future.
