I have a web app that needs to use Oauth 2 to authenticate with Google Apps for Education. I am the admin for the Google domain, as well as the developer, and so I have access to the Admin Console and the Developers Console. Each console has a method for generating an Oauth client ID and secret, and I've done it in both, but I don't know which one to use. I've tried using both of the ID/secret pair, but I keep getting an "unauthorized" error in my app.
If I could at least know for sure I'm using the correct pair, it would help me debug my app.
