OAuth 2.0

I am attempting to have a third party web service initiate a webhook. In order to do this, I need to provide that service authorization to Quickbase via Oauth 2. Here are the fields it is requesting....

URL

Token URL

Client ID

Client Secret Key

Scopes (Optional)

I have tried all sorts of different configurations of information to try and get this to work but have failed so far. Any help would be greatly appreciated.
