How can I post new comment with Graph API into Social Comments Box?

by

I can give you half the answer to this question, but still need the other half very much myself. You can post a reply to an existing comment within Social Comments box by finding its post_fbid. To get this you can use FQL such as:

https://api.facebook.com/method/fql.query?query=SELECT post_fbid, id FROM comment WHERE object_id IN (SELECT comments_fbid FROM link_stat WHERE url="[ PAGE_URL ]")&access_token=[ ACCESS_TOKEN ]

This query will need to be run through an escape() with the PAGE_URL and then used for an HTTP GET request:

https://api.facebook.com/method/fql.query?query=SELECT%20post_fbid%2C%20id%20%0A%20%20%20%20%20%20%20%20FROM%20comment%20%0A%20%20%20%20%20%20%20%20WHERE%20object_id%20IN%20%0A%20%20%20%20%20%20%20%20%20%20(SELECT%20comments_fbid%20%0A%20%20%20%20%20%20%20%20%20%20%20FROM%20link_stat%20%0A%20%20%20%20%20%20%20%20%20%20%20WHERE%20url%20%3D'http%3A%2F%2Fexample.com')&access_token=[ ACCESS_TOKEN ]

With the post_fbid you can make a reply by doing an HTTP POST to:

https://graph.facebook.com/[ POST_FBID ]/comments/?access_token=[ ACCESS_TOKEN ]&message=[ MESSAGE]

Now for posting a new comment to the page this used to work until recently with an HTTP POST:

http://graph.facebook.com/comments/?ids=[ PAGE_URL ]&access_token=[ ACCESS_TOKEN ]&message=[ MESSAGE]

But currently this is consistently returning:

{
  "error": {
    "message": "An unknown error has occurred.", 
    "type": "OAuthException"
  }
}

I hope this helps a bit and if anyone can shed some light if posting a new comment like this is even possible anymore it would be greatly appreciated.
