The Payments Broker Integration Specification documents the interface that a merchant should adhere to,
when utilising the Payment Broker to act as an intermediary between a customer or merchant
and the integration required to process a payment via the Payment Gateway payment checkout page.
This document should be read in conjunction with the Payments Gateway Merchant Interface Payments Page (see Related Links).
The Payments Broker will facilitate the creation of an encoded URL that will act as an intermediary between the customer and the Payment Gateway.
The merchant can present the URL to their customer (via email, web or SMS for instance) which when selected will provide the required information
to request a credit–card payment from the customer for a specified product and amount.
The Broker manages the interaction between the customer and the payment page via a call to the Payment Gateway, and also manages the response back
to the merchant via the call–back information; passed to it, when the Broker URL is requested (including the outcome of that payment;
and if successful, a unique TransactionID and the amount paid by the customer).
