Get Transactional Data

The Payment service API provides the Company a single point of integration with Amazon to facilitate payment processor integration. The payment service allows the Company to complete one integration while getting access to multiple payment processors.

Note: In the future, new attributes might be added. We recommend that you structure your code so that it can handle new attributes gracefully
