The purpose of this document is to explain the Scan to Pay Query Notification API.

This API can be used for merchants and payment service providers (PSPs) who operate in the physical and face to face environments, and provides a means for querying the status of a transaction performed on the Scan to Pay Remote Authentication (MRA) system. This function is only available for integrations using the Secure MOTO and Face to Face API. It can be used to query Purchases, Reversals and Refunds.
