google+ api person's friends

Question

I am trying to make a website based on google+ api. I just started looking into the api and it seems they dont have a method to extract a person\'s circles and friends as facebo

Answer 1

There is an undocumented API. Google+ makes these calls to render Google+ pages:

in X’s circles:

https://plus.google.com/u/0/_/socialgraph/lookup/visible/?o=%5Bnull%2Cnull%2C%22GOOGLEPLUSUSERID%22%5D&rt=j

in whose circles?

https://plus.google.com/u/0/_/socialgraph/lookup/incoming/?o=%5Bnull%2Cnull%2C%22GOOGLEPLUSUSERID%22%5D&n=1000&rt=j

via Fragment: Looking up Who’s in Whose Google+ Circles…

Peeking at the Google+ source code reveals a whole bunch of other URL's:
