google-plus-domains - Is Google plus Domains api working

Question

I'm unable to use Google plus Domains API, even from the API explorer. I tried to explore some methods in domains API, but I failed. For example plusDomains.people.get give userId as "me". authorized with my domain admin account. I got the below response.

  403 Forbidden
