When customers make one or more in-app purchases in your app, the App Store emails them a receipt. The receipt contains an order ID. Use this order ID to call Look Up Order ID. Customers can also retrieve their order IDs from their purchase history on the App Store; for more information, see See your purchase history for the App Store, iTunes store, and more.
