5.3 IAP Question

Hello everyone, I followed the step-by-step guide here http://unity3d.com/learn/tutorials/topics/analytics/integrating-unity-iap-your-game-beta?playlist=17123 for setting up some basic IAP.

My question is in the code provided where would I throw any developer IDs to link the purchase directly to the Google account or Apple App Store Account or the Windows Developer Account so that my client can make money?

Ok I made a video after figuring this out and if anyone has questions here it is.
