Hi,
First you need to submit the paperwork for the Premium Developer program if you haven't already. Other than that, check out the iap /iap-a /iap-b code in the developer kit, and I think we will need to make some settings changes on the back end for your account to make it work. To test, create everything as private channels and publish them, then once it is all working, you will create a public channel and purchase items
