I was playing with facebook graph api, where I wanted to get the posts by me and it's related comments.
I get all posts of using me/posts/ and the id of each post is appended with the user-id i.e if my user-id is 1234 then the list of post would be like (JSON):
{
id:1234_50
}
{
id:1234_51
}
{
id:1234_53
}
And now if I copy the post-id and paste it to facebook.com/1234_53 then it redirects me to that post. Ok that's fine, facebook identifies that the left part of _ is user-id and right is post-id.
But when I dive some more deeper and query the api for the comments of posts using <post-id>/comments, it returns me the metadata for comments. Again each comment has a unique id. Suppose post 53 has a comment having id= 777. So the JSON returned for that is id:53_777. Now when I append this to facebook.com/53_777, this time api identify the left part of _ as the post id and the right part as the comment id.
I am curious to know how api working differently in above scenarios?
NOTE: I am thinking all this in an RDBMS perspective where user, posts and comments must be having separate tables
you can use :
me/posts/?fields=comments{id}

I'm using Instagram Mentions API and was able to obtain FB media_id for couple Instagram posts.
I need media_id to get post content via /user/mentioned_media. Unfortunately that endpoint does not provide ig_id or shortcode or permalink which I need.
Is there a way to get Instagram Post URL with FB Graph API media_id?
It seems like you can get media metadata (and all comments/replies) when someone #-mentions you in a non-owned-media comment by using a query like below.
You would use your own instagram business account id for the first number (the path component), and you'd use the comment_id you received from the webhook comment-mention notification as the second number:
/12345678901234567890?fields=mentioned_comment.comment_id(9876543210987654321){id,text,username,timestamp,media{id,media_type,media_url,permalink,username,like_count,comments_count,comments{id,text,username,user{id,username},like_count,timestamp,replies{id,text,username,user{id,username},like_count,timestamp}}}}
Yes, there is a way you can get Instagram post URL associated with a media if you know the media id.
You can also get more information (all its fields and edges) on media. See the docs here
You can get the Instagram post URL by making a GET request to /{ig-media-id}
Sample Request:
GET https://graph.facebook.com/v15.0/{{media_id}}?fields=permalink, shortcode&access_token={{ACCESS_TOKEN}}
Sample Response:
{
"permalink": "https://www.instagram.com/p/Clxsi5Pol2_/",
"shortcode": "Clxsi5Pol2_",
"id": "17xxx59557977xxx"
}
The value of the permalink is the valid public URL for the post.
You can also use the shortcode returned to construct the URL by concatenating the shortcode to https://www.instagram.com/p/.
I recently made a fanpage and i have used embedded code from one of the post of my fanpage to my website.
So now It shows the post on my website and number of likes but i would like to show current existing comments which that particular post had got. Right now it is just displays the comment button and if i will click that then it will take me to the fanpage just for the sake of comment.
So heres what i need
1 - Comment on the embedded post without leaving the website to facebook.
2 - Displaying all the current existed comments ..
the image right now look like this
Thats very simple. First, you need to login user and ask for publish_stream permission. After the user is logged in, you just to display a button that triggers the function named comment, passing the ID (corresponding to the object user is going to comment to) .
You will also need an input field for inserting the comment (of course), and using jquery .value we will get the value of the input field .
PS: Specify NAME and ID on the message input field. I dont remember wich one is, put both of them .
After getting the variables, we will call FB.api, specifing the variables id and comentario than get the response for handling the result (if you want), you can try to reload the comment plugin, or refreshing the page .
function comment(id) {
var id = id;
var comentario = document.getElementById("message").value;
FB.api("/"+id+"/comments","POST",
{
"message": comentario
},
function (response) {
if (response && !response.error) {
alert('Comentado !');
} else {
alert('Erro !');
}
});
$("#atividade").html('COMENTADO');
}
That is very simple and fun, but you will need to get authorization from facebook platform to ask users for publish_stream permissions before production .
I think David's answer will just post a new comment, not show all post's comments.
Unfortunately there is not a option to show the comments on embed posts.
You need to get the post id, call a api to load all comments and so embed each one of them. Yeah, that's terrible...
Open the graph api explorer:
https://developers.facebook.com/tools/explorer/
Type {post-id}/comments on GET input and send it to see a response example.
And that's how you embed comments:
https://developers.facebook.com/docs/plugins/embedded-comments
I don't think loading all comments from all posts will have a good performance. I suggest you to create a button "see comments" which call the api. After that you can create the input text for new comments, like David said.
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 wan't to Post a comment on a Page Post.
No Problem works finde with:
FB.api('/MY_ID_FROM_PAGE_POST/comments', 'POST', {message: 'test'}, function(resp){});
now i want to tag a user.
I try it with the notifications notation. Like:
{
message: 'test #[AVnA0866TTQbPZuYWv1vZlCEBZBEUIbFskwYZ6DEFEesHck54azfmccyw0YA5w129Q2dOey64hgXNdOLJhCZUo_3J-EHEZwS4lIzPm2egWsSZQ]'
}
Couse of Api Verison 2 i did not become the real user id. I only become this string as a id for the users. Does someone has a solution for this problem?
Have you used the example on taggable_friends, as shown here: https://developers.facebook.com/docs/opengraph/using-actions/v2.0#mentions
You should first receive the ids of the users you can tag using user/taggable_friends endpoint. Then you can use those IDs in the post you create.
Does that work?
Is there a way to retrieve the list of Facebook users that have clicked the like button on an external website?
E.g. there is a domain example.com which has been confirmed via Facebook Insights to belong to fbUser1 (using OG meta tags).
Somewhere on example.com there is a page with multiple XFBL like buttons, each one pointing to a further specific URL on example.com, e.g. example.com/xyz, example.com/abc etc.
What I'd like to get is the list of users that liked example.com/xyz and of those who liked example.com/abc.
My intuitive approach would be to look at graph.facebook.com/123456789/likes (where the number is the ID of the domain taken from FB insights), but this always returns an empty dataset:
{
"data": [
]
}
I've also tried getting an OAuth access token from https://graph.facebook.com/oauth/access_token?type=client_cred&client_id=APPID&client_secret=APPSECRET (where APPID and APPSECRET are taken from a FB application that is marked as owning the domain using OG meta tags), but that makes no difference.
I'd also be interested in a non-OpenGraph (i.e. JS SDK, FQL etc.) solution.
EDIT: Using the following code (according to WideBlade's answer below) still gives me an empty list of likes (the second query never returns):
var objectsQuery = "select id from object_url where url in ('http://example.com/xyz', 'http://example.com/abc', 'http://example.com/123')";
var likesQuery = "select object_id from like where object_id = {0}";
FB.Data.query(objectsQuery).wait(function (objectRows) {
console.log(objectRows);
FB.Array.forEach(objectRows, function (objectRow) {
FB.Data.query(likesQuery, objectRow.object_id).wait(function (likeRows) {
console.log(likeRows);
})
});
});
FQL Should do the trick.
$facebook->api_client->fql_query('SELECT user_id FROM like WHERE object_id="OBJECTID"');
Here is the link.
Some general info about FQL.
FQL is initiated using the JavaScript SDK, in this way.
If you can post some sample code-I can try and give some more specific help.
A note should be made-once you've got the user ID's, you can just query the names and get them in a list.
EDIT: To get the URL of an object you should query this table using fql.
This cannot be done. Facebook does not allow you to query for specific user ID's of people who have liked a certain page. This is because of privacy concerns.
See the disclaimer on this page https://developers.facebook.com/docs/reference/fql/like/
