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 have an access token with the manage_pages scope. Using this token, I call the endpoint specified here (GET /{page-id}/photos?type=uploaded).
The result is for some reason lacking all attributes except id and created_time. This is a part of the response:
"data": [
{
"created_time": "2018-10-30T18:12:31+0000",
"id": "1172525292900120"
},
{
"created_time": "2018-10-30T18:10:08+0000",
"id": "1172524459566870"
}
]
The docs says that data should contain "A list of Photo nodes". Looking at the photo node docs, it seems they have exactly what you'd expect.
My app does not have the permission Page Public Content Access yet. But according to their App Review section, it isn't needed for accessing my own page's content. And then again, I wouldn't even be able to get a list of photos if I didn't have access to the page.
While you are testing your app and before you submit it for review, your app can only access content on a Page for which the following is true: The person who holds the admin role for the Page also holds an admin, developer, or tester role on the app.
Why am I missing some attributes in the Photo nodes?
I had to specify which fields to retrieve like this: GET /{page-id}/photos?type=uploaded&fields=images.
Long time lurker first time poster...
We are working with Facebooks API's to integrate into our web application and we are able to pull a Companies Page Rating via the {open_graph_story} parameter in the {page-id}/ratings section, however we cannot find a way to comment/reply to the rating. The documentation states:
"If a person has rated your page and a story has been generated, you can follow up with the person by posting to the story's comment node." (https://developers.facebook.com/docs/graph-api/reference/v2.0/page/ratings)
however when we pull the variables we retrieve no ID to reference for a comment. This is what we receive back from our authenticated account:
"data": [
{ "created_time": "2014-07-16T05:52:50+0000", "reviewer": { "id": "100000237096397", "name": "Romey Salazar" }, "rating": 5, "review_text": "Great job guys!!!!" } ],
Does anyone know how to retrieve the id for the rating itself so we can append a comment via API? Or some other way to reply/comment to a FB Page Rating?
Thanks!
When you have some ratings/review comments on your page and if you want to post comment to individual review comments as the Page Owner, you can follow the steps below.
1) Below request returns the json object of rating and reviews.
https://graph.facebook.com/v2.9/{YOUR_PAGE_ID}/ratings?field=open_graph_story&access_token={YOUR_PAGE_ACCESS_TOKEN}
The response json will contain ID field for each and every rating/review comments.
2) Using the ID, trigger the below request to post a comment on the rating as the Page Owner. You will need Page access token with manage_pages and publish_pages privilege.
https://graph.facebook.com/v2.9/{ID_OF_THE_RATING}/comments?message=Thanks for your rating&access_token={YOUR_PAGE_ACCESS_TOKEN}
These requests can be tested using Facebook Graph API Explorer
You need to request the open_graph_story field with the ratings endpoint. This will return the open_graph_story data which includes an id. You can then post to the comments endpoint of this story.
You have to make http get request on
https://graph.facebook.com/v2.9/{PageID}/ratings?fields=open_graph_story&access_token={PageAccessToken}
to get detailed response.
Make sure the parameter is "fields" not "field"
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.
Source: https://developers.facebook.com/bugs/290004301178437/
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.
I have a user, user_2. There is a post on their wall, made by user_1.
The URL is
https://www.facebook.com/user_1/posts/10150166228506188
I try to get the content using the Graph API, with this request:
https://graph.facebook.com/10150166228506188?access_token=ACCESSTOKENUSER_2
I get this error:
{
"error": {
"type": "GraphMethodException",
"message": "Unsupported get request."
}
}
The access_token I am using is good, because requests to get things like statuses & images work fine:
https://graph.facebook.com/10150233707783933?access_token=ACCESSTOKENUSER_2
Result:
{
"id": "10150233707783933",
"from": {
"name": "American Steel",
"category": "Professional sports team",
"id": "203692078932"
},
"tags": {
"data": [
etc
The error seems to happen whenever I try to get items that have this kind of URL:
https://www.facebook.com/username/posts/item_id
The permissions my app has include these:
Why is this error occurring?
I think that, in order to access the posts directly through the graph api, you have to prepend the user id to the post id you see in the facebook url.
So in your example the facebook post url is :
https://www.facebook.com/user_1/posts/10150166228506188
And you try to get through the graph api :
https://graph.facebook.com/10150166228506188?access_token=ACCESSTOKENUSER_2
BUT you should be doing :
https://graph.facebook.com/{id of user_1}_10150166228506188?access_token=ACCESSTOKENUSER_2
I noticed that all posts ids are formed like this by visiting :
https://graph.facebook.com/me/posts?access_token=...
Does this solve your problem ?
You're accessing the end-point of the post incorrectly. Every object on Facebook has a unique ID. Right now, it just so happens that they form it by appending different IDs together (your post is an example, <user_id>_<post_id>, and for a comment on that post it'd be <user_id>_<post_id>_<comment_id>). Facebook hasn't made public acknowledgment of this (not that they really have to, it's obvious) which makes me leary to rely on that paradigm for accessing data within the graph. This is because Facebook could change it at any point, and the fact that they haven't said "yeah append these 2 ids together and you can get something meaningful from this part of the graph" means they won't have to notify anyone about the change, you could just wake up one day and your app be completely broken and you'd have to find a work around quickly and while suffering down time.
The graph api works by accessing objects on Facebook by making a request to the API for that unique ID. So, you don't need to access (and can't access) your posts by going to graph.facebook.com/<user_id>/posts/<post_id>. Instead, you go to graph.facebook.com/<post_id>. You get the post_id from the /<user_id>/home or /<user_id>/feed end-point on the graph. There is no need to modify a post_id in order to fetch information about it from the graph.
Hope that helps
