strongloop - LOOPBACK: getting third party api (instagram) via loopback api -

so, here goes...

i building app, (among other things) provide instagram, twitter, fb , yt live feeds on specific hashtag

what achieve if query loop api http://localhost:3000/api/socialfeeds/instagram/xy

where loopback app query third party api (instagram) in case... , feeds hashtag 'xy'

now, read this article using rest connector hook 3rd party api... great! (love loopback soo much)

but, doesn't provide example, you'd first need authenticate (get access token) in order use api.

any ideas how can that?
