Then you chose the wrong authentication scheme. In your SO post you linked 
to the web app authentication scheme. If you have no users and need to 
connect to Google, you need to use the Service Account authentication 
scheme (it's the second radio option on the second picture in this album:

is here: https://developers.google.com/accounts/docs/OAuth2ServiceAccount but 
essentially you have to cryptographically sign yourself. There is a library 
and code example here:
