The instructions you have for setting up Google Drive don't match the setup requirements in:
To create an application for Google's APIs, go to the API console:https://console.developers.google.com
in some respects in the Credentials section. For example:
No "OAuth client ID selection.
No 'Web Application' in the 'Where will you be calling the API from?' dropdown list.
I guess their process has been updated. Please advise the current setup process - where it has changed from your instructions.
Thanks...Andrew
It's not trivial to always catch-up with the ever changing config screens for all the services we support. In this case for google, choose the type "Other".
Yes, I understand and sympathise. Thanks.
