  • Facebook API: retrieve comments

Lets say i have a blog, and a normal comment box below it, not facebook comment box.

I created an app which posts all of my new posts to the user's wall, if he commented on my post, could i send this comment from facebook to appear in my comment box?

or could i create a text box on the user's stream under my posts? instead of the comment box?

I'm interrested in using python sdk, or php sdk, or javascript sdk, but python is my first choice.

To further clarify my question, I'm interested in creating something like the guardian app which keeps posting to the user's wall,if i have a guardian account, i could send comments from my facebook app to the website. I don't want to use facebook comment box though.

I have never seen a facebook app that does that, therefore I'm asking if this could be done.
The facebook graph api is available in all the sdks you posted, so anything in the API docs can be found in any language supported by the SDK.

Concerning the comments, you can retrieve facebook comments to a certain post via:
https://developers.facebook.com/docs/reference/api/Comment/

Of course this is not that simple, you would need a valid access token to retrieve the comments.
But you can certainly use the above API to start your tests.
