About the APIs for Implementing Custom Payment Cassette Cartridges

You can implement custom payment cassette cartridges with Oracle Billing Insight.

Oracle Billing Insight provides a set of well-defined interfaces for payment gateway integration, and it enables you to develop or customize the cassette according to your payment gateway requirements. You must set up the gateway to communicate with Oracle Billing Insight. You do not have to change anything internal to Oracle Billing Insight.

Figure 20 shows an overview of the interaction between the payment cassette cartridge, Oracle Billing Insight, and the payment gateway.
