Has anyone successfully worked through the Google Spreadsheet application from https://gethelp.wildapricot.com/en/articles/485-sample-api-applications ?
It seems to be missing a lot.
Following the instructions I get Exception: Request failed for https://oauth.wildapricot.org returned code 400. Truncated ser.....
There is noting on setting it up as an authorized application or entering the API key (which I have done). Also nothing on the Application Name.
There just seems to be a lot missing (like trigger deployment in Google sheets).

Can anyone shed any light on this ?
