I was wondering if it is possible to look up a user using the fbid that gets shown when using the Instagram API to look up a user. For example, I used the following URL to look up the official Instagram account:
https://www.instagram.com/instagram/?__a=1
This URL returns a JSON object and within that there is a fbid key like so:
"fbid" : "17841400039600391"
Is there anything useful that can be done with this fbid such as looking up a user?
