Oauth using Google/Facebook/Linkedin BUSINESS PAGE (not personal)

Hi all,

Does anyone have any experience (even if not on meteor) for using an Oauth strategy using data from business pages?

I know https://buffer.com lets you connect your linkedin/facebook business page-- so as to let you post social media stuff to them. So it must be possible. However, I haven’t found much about how to do it-- let alone any meteor packages.

I’m just looking to be pointed in the right direction.
