I successfully managed to retrieve first 50 photos of a public page via FBGraph but can't make pagination work
1525666877712653?fields=albums{id,photos.limit(50){name,picture}}
Here's, for example, how I get them from CocaCola's public page. But how can I get 50 more?
When doing
1525666877712653?fields=albums{id,photos.limit(50){name,picture}}
You will get:
{
"data": [
... Endpoint data is here
],
"paging": {
"cursors": {
"after": "MTE1NzQxNDAwODUwNA==",
"before": "MTU0MjU3NDQ3NzI3NQ=="
},
"next": "https://graph.facebook.com/v2.3/1525666877712653/albums?fields=id,photos.limit(50){name,picture}&limit=25&after=MTE1NzQxNDAwODUwNA=="
}
And use the query you can get from the next field to get the results from 50 to 100. You will see that the filters are the same as in your initial query.

I'm trying to get all comments from Facebook Comments Plugin running in my application.
Here's a step by step of what i have done
https://graph.facebook.com/{myUrl}
{
"share": {
"comment_count": 43,
"share_count": 1695
},
"og_object": {
"id": {myObjectID},
"description": {myDescription},
"title": {myTitle},
"type": "website",
"updated_time": "2018-05-28T21:50:37+0000"
},
"id": {myUrl}
}
https://graph.facebook.com/{myObjectID}/comments?access_token={pageToken}
{
"data": [ ],
"paging": {
"cursors": {
"before": {beforePointer},
"after": {afterPointer}
},
"next": {nextUrl}
}
}
So despite comment_count = 43, data field is empty.
It's also weird that a {nextUrl} is given although not showing any results.
Haven't found nothing about this in the recent update due to GDPR.
Any ideas?
The graph API has changed recently due to privacy and GDPR concerns.
To get all comments for a page or user first you need to make a call to get all your posts and then make a call for each post to get comments.
Please view the following example end to get all the posts and then post_ids (the call is similar for user posts).
https://graph.facebook.com/v3.2/{pageId}/posts?access_token={accessToken}
post_id looks something like this - 5704324444475_570454233326 and is in the id field of each returned post.
Then call the get comments endpoint from the graph API using the ID(s) returned by the first endpoint.
https://graph.facebook.com/{post_id}/comments?access_token={accessToken}&summary=true
You'll need to make a separate call for each posts to get that post's comments.
I'm playing with facebook explorer to get event photos urls.
For {event-id}/photos I get something like:
{
"data": [
{
"created_time": "2015-12-07T20:53:44+0000",
"name": "1913 rok.",
"id": "178797088851556"
}
],
"paging": {
"cursors": {
"before": "OTc4Nzk3MDg4ODUxNTU2",
"after": "OTc4Nzk3MDg4ODUxNTU2"
}
}
}
How can I exctract this photo (id: 178797088851556) url?
It´s called "Declarative Fields":
/{event-id}/photos?fields=name,source
Check out the API reference for all available fields.
I'm currently building an experimental social network to study the influence of social medias on customers behaviors.
My users log in through Facebook OAuth provider. I store their access tokens and query the Open Graph API to fetch info about them.
I'm trying to use the all_mutual_friends edge for a given user context, using the access token of one of my users, but I found nowhere how to get the user-context-id that is required to get that info.
It is not the id of the user you want to retrieve the mutual friends from. I've tried that and got an error.
I've skimmed trough Open Graph docs and found nothing about that user-context-id.
How can I retrieve it?
Odly enough, the docs do not specify how to get the context id, but I managed to get it by digging a little.
This is how you would do to get the all_mutual_friends data:
GET /{user-id}?fields=context.fields%28all_mutual_friends%29&access_token={other-user-access-token}
Then, the context id would be given in the response.
{
"context": {
"all_mutual_friends": {
"data": [
{
"id": "1381033095543871",
"name": "Dave Amiaaehjighi Putnamwitz",
"token": <user token>,
"picture": {
"data": {
"is_silhouette": true,
"url": "https://fbcdn-profile-a.akamaihd.net/hprofile-ak-xpf1/v/t1.0-1/c15.0.50.50/p50x50/10354686_10150004552801856_220367501106153455_n.jpg?oh=82c2ce067f9c7f2c0a66d1efb16730e7&oe=5670F72F&__gda__=1450287355_17925d7381c8da5663c2349483f4b032"
}
}
}
],
"paging": {
"cursors": {
"before": "MTM4MTAzMzA5NTU0Mzg3MQZDZD",
"after": "MTM4MTAzMzA5NTU0Mzg3MQZDZD"
}
},
"summary": {
"total_count": 1
}
},
"id": <Context id>
},
"id": "1375274282788732",
}
That context id could then be used for
GET /{user-context-id}/all_mutual_friends/
But this step is pretty useless since we get the data in the first query.
Would be nice if Facebook updated their docs to reflect reality.
I'm trying to get the total likes count for posts by a specific user. I'm calling /photos /links and /statuses. When adding ?fields=likes.summary(true) I'm getting back the total sum of likes in /photos and /statuses, but this doesn't work.
How can I get summary of likes (total count) for links posted by a specific user?
I am aware of the option to use FQL, but that is deprecated. (fql?q=SELECT like_info, link_id,comment_info FROM link WHERE link_id IN() )
Use the links edge
me/links?fields=link,likes.summary(true)
The total_count field is the value you want. Although from the documentation
total_count represents the approximate number of nodes on the likes
edge. The actual number of results returned might be different
depending on privacy settings.
Sample data from my feed
{
"link": "http://www.quora.com/permalink/cyGokoKWB",
"id": "XXXXXXXXX",
"created_time": "2015-04-26T02:08:48+0000",
"likes": {
"data": [
{
"id": "XXXXXXXXX",
"name": "XXXXXXXXX"
}
],
"paging": {
"cursors": {
"before": "MTAxNTQ2NTI3OTIxOTA0Mzg=",
"after": "MTAxNTQ2NTI3OTIxOTA0Mzg="
}
},
"summary": {
"total_count": 1
}
}
}
EDIT
#CBroe in the comments has sound advice, for just like's count do a limit(0) so you don't unnecessarily fetch a lot of the likes data and just retrieve the count.
me/links?fields=link,likes.summary(true).limit(0)
Sample data
{
"link": "http://jdh.hamkins.org/transfinite-epistemic-logic-puzzle-challenge/",
"id": "XxXXXXXXXXX",
"created_time": "2015-04-19T04:00:18+0000",
"likes": {
"data": [
],
"summary": {
"total_count": 1
}
}
}
we are using the facebook timeline phtot stream, to show the last photos on the website.
We are parsing the url: http://graph.facebook.com/132827113407662/photos
If you have a look at the 5th pic, it shows 25 likes.
If you look at this pic on fb (https://www.facebook.com/photo.php?fbid=635486689808366&set=a.132827113407662.19448.114902408533466&type=1), it shows 31 "Likes".
How can I get the correct number of "likes".
It seems, that the largest number in the stream (http://graph.facebook.com/132827113407662/photos) ist 25. Any like higher than 25 will be ignored in the stream.
Why?
Likes collection is paginated. You can read more about pagination here.
Looks like there is still no way to get all rows count for a collection using graph api request.
But you can get it through FQL.
select like_info, object_id from photo where album_object_id = 132827113407662
Returns:
{
"data": [
...
{
"like_info": {
"can_like": true,
"like_count": 31,
"user_likes": false
},
"object_id": 635486689808366
},
...
]
}
Using the Graph Api you can request fields summary like this: ?fields=likes.limit(1).summary(1)
And the page/album/photo likes are contained in the summary.total_count object.
http://graph.facebook.com/132827113407662/photos?fields=likes.limit(1).summary(1)
This will give you as follows:
{
"data": [
{
"id": "690240794332955",
"created_time": "2013-10-31T18:11:07+0000",
"likes": {
"data": [
{
"id": "100003293421476",
"name": "Rene Geels"
}
],
"paging": {
"cursors": {
"after": "MTAwMDAzMjkzNDIxNDc2",
"before": "MTAwMDAzMjkzNDIxNDc2"
},
"next": "http://graph.facebook.com/690240794332955/likes?summary=1&limit=1&after=MTAwMDAzMjkzNDIxNDc2"
},
"summary": {
"total_count": 78
}
}
}
]
}
