What exactly is needed to publish to Google plus with its APIs

1

My question is about the Google+ Domains API

From this answer is said: "There is currently no public API to publish to Google +."

So, look for other questions and answers, I see the possibility of POST with Google + Domains API through the Google domain account.

Then again, many doubts came up:

1- What is the Google Domain account and how do I set it for the purpose of posting to Google Plus (Profile / Page or Communities)?

I learn about OAuth2 and git google respositore php class library .

In some tests (from localhost), I get authorization and accessToken, but always with errors like this at the end: Prohibited or invalid credentials.

In my searches, the error is because I do not use Google Domain Acccount.

So I do not see in all of Google's results how to do this end-to-end, to create Google Account Domain for POST in Google Plus.

I'm not asking for a complete tutorial, just the way for one I do it.

After 5 consecutive days, here's my last attempt (or not, who knows), but I'm tired and I can not see the light at the end of the tunnel.

All tips are welcome.
