How can I post new comment with Graph API into Social Comments Box?
I’m trying to POST a comment to a page URL in order to reproduce the comment widget functionality using the graph API. While I can get the post_fbid of an existing comment and post a response to it, I cannot post to the page itself. I’ve tried using the comments_fbid (link_stat table) and the object id (object_url table) and both return An unknown error has occurred. error messages.
This question has been asked before here and here, but I’d like do know definitively if it is not possible.
This does not seem to be possible currently. Here’s the FB bug tracking the issue:
