  title: eBay Order Confirmation Notifications
  version: 1.0.0
  description: 'An ORDER_CONFIRMATION notification is sent when a buyer completes the checkout process for an auction or fixed-price item. Usually, an ORDER_CONFIRMATION notification occurs only once per listing. However, if the payment for checkout fails, the checkout status will change from "complete" to "incomplete." If the buyer then successfully pays for the item via checkout, the checkout status will change back to "complete" again. When the checkout status changes back to "complete," another ORDER_CONFIRMATION notification will be sent. An ORDER_CONFIRMATION notification is generated for each line item in the order. The seller looks up the orderId from the notification and then issues a GetOrders call (using the orderId as an input filter) to retrieve complete order information.'
