Hi Tony,
I suspect that error message is the Apptio web page returned when there are issues with the API call (invalid parameters in the call, user account is not an admin or service account, or many other issues).
I did build an excel macro some years ago that would make GET calls to Apptio API end points and load the response into a worksheet. A clunky solution but did get it to work. Happy to catch up and run through it at some point.
Cheers Mark

Subject: How to use an Apptio API GET in Excel Power Query via JSON
Has anyone have success in using the JSON API to use the GET from Web function within Excel's Power Query to pull data?
Tried following the instructions from the MS article -- Using a REST API as a data source and I keep getting an error message as below.
