I have read loads of good documentation and example for getting external API's to work in Google Apps Script and also access Google API's with OAuth and have successfully integrated them. I can't however find any help with getting the Google+ Domains API https://developers.google.com/+/domains/ working in GAS.
I understand its a little different as it has the capability to do domain wide delegation of authority (which is what I want).
If anyone can help point me in the right direction that would be great.
Many thanks.
