I've been having some problems trying to understand the Oauth requirements for Server-side applications which don't require User interaction when querying google API's.
Apologies if this seems obvious to most, but the issue I have is that all the examples and Oauth flows are based on prompting a user to either authorize which features the application has access to or authenticate the user with a google account before being granted a token and refresh token.
Does anyone have experience querying the Sheets API from a server side app without user interaction that could give me some pointers on how to create the Auth token?
I'll be using Javascript, AJAX and JSON to call the REST API.
Many thanks, Billy
