Retrieve facebook user name

[samt07]

I am using node.js and integrating my Wit.ai app through Built in NLP. I would like to retrieve the username when a facebook user initiates a chat with my bot. Is it possible to retrieve that information?

Thanks

I found a way to do this by using the facebook messenger profile documentation. Marking this as closed.
