I'm trying to access the Google Analytics API via Google Sheets (Google Script).
So within the script, I'm trying to use the URI as described here: https://developers.google.com/analytics/devguides/reporting/realtime/v3/reference/data/realtime/get
The API call looks something like this:
GET https://www.googleapis.com/analytics/v3/data/realtime?ids=3254435&metrics=ga%3AActiveUsers&key={YOUR_API_KEY}
Within my Google Analytics Script, I've also created a Public API Access key: 
However, I can't seem to get any data whether if I'm appending the token key in the URI or within the header.
Can any one point me to the right direction?
Thanks
