I own a page and I'm trying to fetch comments on each post. On Facebook page itself I can see the count value is 137 as per below Image
When I've tried to retrieve those comments using graph API I got 89 only. Where did this variance came from? I'm calling the comments endpoint using page access token. I shall see every comment, even the private comments as well.

I am trying to fetch all of my instagram page's posts (around 57k posts) from facebook's graph API. using the 'media' endpoint described here:
https://developers.facebook.com/docs/instagram-api/getting-started
I have managed to get around 12k posts using it using the query below:
https://graph.facebook.com/v3.3/{ig-user-id}/media?access_token=XXX&pretty=0&fields=timestamp,caption,comments_count,like_count,media_type,media_url,owner,permalink,shortcode,thumbnail_url,username&limit=200
when using this link returning result contains a data part which is for posts' data and a pagination section which includes next and previous urls and cursors for after and before. I used next and got remaining posts each time, until the result didn't have a next url but it had an after cursor but when I used it the data returned was empty.
I thought there might be some kind of limitation, but couldn't find anything so far except for the API rate limits which I don't exceed.
I also tried the graph API explorer and got the same result.
The problem was not solved but I found something I hadn't seen before, it might help people confused like me.
in the endpoint documentation it is declared that this endpoint has a 10k recent posts limitation, therefor we cannot get any more of our posts.
The Short Version:
"I can visit the public page without being logged into Facebook and see underneath the post is says "2155 shares" I would like to know how to access that number through the API"
The Details:
I'm trying to use the newest version (v2.5) of the graph HTTP API to determine the total share count for a public video. The problem is FB seems to have changed the API enough that older posts on SO no longer answer this question.
Looking at the Graph API Documentation it appears that video nodes now have the "sharedposts" edge. However, calling this route with summary=true only returns a few of the shares and no value for a total count. This returns counts for comments and likes so I'm not using the endpoints incorrectly or messing up my authorization.
I've also tried to use the URL Node but this doesn't seem to do much with links inside of Facebook. I simply get a JSON response with an 'id' field with the same url I supplied as a request parameter. Seems like this route is meant to be used for links to content outside of Facebook.
I've tried the above methods with multiple videos on multiple public pages so I don't think it is due to the group owners restricting access, unless this is the new default.
It seems arbitrary that I would be allowed access to total counts for comments and likes, but not shares. Is there some legacy way to do this or am I out of luck for now?
You should query the Post element containing the Video element.
Each video posted is also contained in a post element.
The post id is then composed of the video id prepended with the posting entities id (user, page etc'), separated with an underscore.
It then looks like: user-id_video-id.
Then using the Graph API to get the share count of a post is straightforward:
GET /v2.5/{post-id}?fields=shares
Example
Lets take a video from the BBC page:
https://www.facebook.com/bbcnews/videos/10153524838517217/
(Please tell me if the link is broken. I'll switch it to something newer :))
Video id : 10153524838517217
Page id (see below): 228735667216
--> Post id: 228735667216_10153524838517217
And the request would be:
GET /v2.5/228735667216_10153524838517217?fields=shares
(open in the Graph API explorer)
Page id
to get the page id, you could query the video element for the from field.
GET /v2.5/10153524838517217?fields=from
In the "Posts" section of Facebook Insights, you can click on your latest posts and get detailed information about them:
I'm trying to recreate this data in a web application, using the Facebook SDK for .NET. I have found most of these numbers through Facebook's Graph API, e.g:
.../v2.3/(page-id_post-id)/insights/post_impressions_unique/lifetime
.../v2.3/(page-id_post-id)/insights/post_stories_by_action_type/lifetime
.../v2.3/(page-id_post-id)/insights/post_consumptions_by_type/lifetime
.../v2.3/(page-id_post-id)/insights/post_negative_feedback_by_type/lifetime
...except the post content and the numbers marked in red. Using Fiddler, it looks like Facebook fetches these values from a URL outside the Graph API:
https://www.facebook.com/ajax/pages/insights/view_story/...
However, that URL is only accessible if you're logged in to Facebook. So, the question is:
Given an access token, can my (server-side) web application somehow get the post content, or at least the missing numbers? Preferably using the Facebook SDK, but any solution will do.
Update:
As #CBroe points out, simply querying the post id itself gives you enough info to recreate the post content:
.../v2.3/(post-id)?fields=name,message,picture,link
So, the last piece of the puzzle is to get the missing numbers. "Likes - On Post" can be found by querying the post's /likes with a summary:
.../v2.3/(page-id_post-id)/likes?limit=0&summary=true
..but "Comments - On Post" and "Shares - On Post" are trickier.
Querying .../v2.3/(page-id_post-id)/comments does give the number of comments on the post, but doesn't include answers to those comments, which are included in the number 5 in the picture above. You can recursively query /comments on each comment id, but that would generate too many queries to be worth it.
One might think that querying .../v2.3/(post-id)/sharedposts could give you the number of times a post has been shared, but it only gives you a few of the shared instances (due to other users' privacy settings?)
to clarify, you're trying to get the number of likes, comments, and shares.
Likes [post_id]/likes?summary=True&limit=0
NOTE: You can also call it when calling the post fields [post_id]?fields=id,likes.summary(true).limit(0)
Comments [post_id]/comments?summary=true&limit=0
NOTE: comments edge has a param filter https://developers.facebook.com/docs/graph-api/reference/v2.3/object/comments which may be why you see different numbers
NOTE: You can also call then when calling the post fields [post_id]?fields=id,comments.summary(true).limit(0)
Shares [post_id]?fields=shares
the sharedposts edge is empty b/c you don't have "read_stream" permission for the user's posts, https://developers.facebook.com/docs/graph-api/reference/v2.3/object/sharedposts#readperms
Edit (by OP):
Adjustments to get the same numbers that are presented in the "Post Details" popup:
Comments - On Post: (page-id_post-id)/comments?filter=stream&summary=true&limit=0
Using only post-id without prepending page-id gives the same result, but you also get a debug message saying "...actual number of results returned might be different depending on privacy settings."
Shares - On Post: (post-id)/sharedposts?fields=id
Don't prepend page-id here - that yields an empty result set.
Sadly, ?summary=true doesn't work, so I used the fields filter just to reduce the amount of data.
The suggested (post-id)?fields=shares gives a different number which seems similar to the insights numbers, but doesn't add up to any of them.
I tried for several hours to get the total number of likes/comments of a photo/post using the new Facebook Graph API 2.1 but I didn't find how to do it.
I am able to photo and post details through the API but it contains only an subarray with some likes and comments (ID/Name pair), but no the total number. Graph API Reference for object/likes mention a total_count field but is not able to found in API response.
Can you please suggest me a way to do it?
I am using latest Facebook PHP SDK 4.
I faced this situation before. Facebook Graph API Explorer, in the Fields dropdown list, you can not find any field related to total_like or total_comment of a specific post ( via its object_id). That means Facebook Graph API does not support getting the total likes, comments of a specific post.
But, it support to get likes, comments data of a post via likes, comments fields. So by this way, you can get the entire data about likes, comments, therefore, you can get the total number of likes/comments. This solution is not good, I think. I think in the near feature, Facebook Graph API support the fields total_likes, total_comments.
/object_id?fields=comments.limit(1000),likes.limit(1000)
I want to get a number of posts from a page in last month. Is is possible with facebook graph API? Also FYI, i just have the access_token to interact with the Facebook API.
Also do anyone knows how to fetch the number of Page mentions in last month?
Thanks for your help in advance.
Try using Facebook's Page Insights using Facebook Graph API's :
https://developers.facebook.com/docs/graph-api/reference/insights/#page_posts
But please note that you need to be a page admin for this page, and you need to acquire a Page Access Token with the permissions 'read_insights'.
If you are not a page admin, then you can also do the same with an User Access Token or an App Access Token.
Steps:
`int postsCount = 0;
Use the following API query https://graph.facebook.com/{page-id}/posts and issue a reuquest.
Count the posts fetched. postsCount = postsCount + {the posts json array size}.
Store the cursor returned by the above API result. Use it to fetch the next page of Posts.
If the {the posts json array size} > 0, then goto step 3.
Notes:
I am sure that you can do it better with FQL, but I am guessing FQL is being deprecated.
I think there is a summary(true) annotation (https://graph.facebook.com/{page-id}?fields=posts.summary(true)) that you can use, but I couldn't get it working.
There is an API rate limit that you need to keep in mind. And do some throttling.
So, the moral of the story is that I am not sure if Facebook really wants you to crawl its Pages if you are not the Admin of the page. :-)
