Facebook Graph API - get latest comments

Question

I'm trying to parse fb feed to find new comments. First I get posts list by this url http://graph.facebook.com/2.0/page_id/posts. Then I get comments by http://graph.facebook.com/2.0/page_id/post_id/comments for each post. I found that I can use batch_requests and http://graph.facebook.com/2.0/page_id/posts?fields=comments. But I want to ask:

1. Can I get and parse only new comments? Not for all existing posts. Can I get response sorted by latest comments?
2. If no, what should I do in next case - Comment for post isn't included in fb/posts because this post created 250 posts before?

P.S. FQL is not good solution because it is deprecated.

Answer 1

You can specify an order of reverse_chronological to get the newest comments first. It's not documented but seems to work from v2.0 on.

i.e. Get all post comments w/ newest first

[post_id]/comments?filter=stream&order=reverse_chronological
