Is it possible to mirror Facebook comments from my Facebook page on a post to my site using the comments plugin? I've been searching and cant really find anything regarding this subject. thanks
If all you need is to "mirror" that, then this is probably possible by using:
GET /{POST-ID}/comments?access_token=PAGE-ACCESS-TOKEN
However, if you are looking for a plugin, the nearest plugin for this is the Embedded Posts but that will only show the numbers of comments:
What do people see in Embedded Posts?
The embedded post will show any media attached to it, as well as the number of likes, shares, and comments that the post has. Embedding posts will let people using your web site see the same rich information that is shown on Facebook.com, and they will enable people to follow or like content authors or Pages directly from the embed.
