Hi Eric!
Do you have the documentation they've provided you? The only things I can see from the AP website say that you need to include the 'x-api-key' header along with your API key, not necessarily using OAuth2. This can be done by going to the custom headers section in the RSS/HTTP Datalinq (should be 2nd tab), and adding a new pair. The key/name is x-api-key, and the value is your personal api key.
