Payment gateway overview

Integrate with CodePay Payment Gateway​

CodePay Payment Gateway is a service that helps merchants initiate online, in-app, and face-to-face payments. It does not directly handle the flow of funds; instead, it typically operates as a network service connected to merchant websites or POS systems. CodePay Payment Gateway combines the functionalities of a payment gateway and processor from banks/acquiring institutions, along with risk management systems and acquiring capabilities. This makes CodePay a full-stack payment service provider. By integrating CodePay's payment capabilities, merchants can quickly and securely access global payment services.
