How to verify facebook access token from client app on my server using passport-facebook-token??

[NikhilBhutani]

I have facebook login in my app, I received the access token from facebook server. Now I'm sending that access token to my server. How can I verify by sending access token from my server to facebook server for two way authentication of this social login using Passport??
Hoping for a reply soon

You should call this endpoint

https://graph.facebook.com/debug_token?access_token=app_id|app_secret&input_token={user_access_token}

See the documentation here
