Authenticating Oauth2 in Google App Script
I'm sure this is a pretty basic question. I'm pretty new to Lightspeed and setting up Oauth stuff. Not so new to Google App Script and I have set up a couple Oauth links before in order to integrate back and forth with other APIs. I'm a little bit lost on how to set it up properly for Lightspeed however.
I've registered for an Oauth client and gotten my ID and Secret. I've gone over the PHP example from github. However, in the Google environment those scripts aren't exactly plug and play and I'm not sure the best way to go forward.
I know it's possible to set this up and I'll keep at it, but does anyone here have first hand experience setting this up or have a link to any kind of example or guide?
