Corona's store module

Applying In-App Purchases in your application can be a little mind-boggling and tedious process. Integrating it with Corona requires calling the store module:

store = require("store")

The store module is already incorporated to the Corona API, similar to Facebook and Game Network. You can find more information on Corona's store module at http://docs.coronalabs.com/daily/guide/monetization/IAP/index.html.

store.init()

The store.init() function must be called when handling store transactions to your app. It activates In-App Purchases and allows you to receive callbacks with the listener function you specify:

store.init( listener )

The following blocks determine the transaction states that can occur during an In-App Purchase. The four different states are purchased, restored, cancelled, and failed:

function transactionCallback( event )
  local transaction = event.transaction
  if transaction...
