Payments

Payment retrieval API

Before you start
The intention of the payment API is to fetch payments upon a user action, often by means of a tender button on a point of sale system.
The payment API will return all relevant payments and does not provide an acknowledgement mechanism. Therefore, subsequent requests with the same parameters will return payments that were included in the previous request, and it is up to the client to ensure that these payments are applied correctly. If an acknowledgement mechanism is required, please use the preferred real-time payment notification solutions documented in the Payment Notifications section.  
Payment polling should only be considered as last resort and may result in request throttling. The preferred alternative is to use the real-time payment notification solutions documented in the Payment Notifications section.
Getting Started
There are three distinct ways in which payments can be retrieved via the payment API.
Using the invoice reference returned from the invoice API.
Using the merchant invoice reference supplied to the invoice API.
Using the ZapperId of the payment itself.
