Payment gateway overview

Integrate with CodePay (Omini payment gateway provided by CodePay)​

CodePay payment gateway is a service that helps merchants initiate online, in app, and face-to-face payments. It does not directly participate in the flow of funds; Typically, it is a network server connected to a merchant's website or POS system. CodePay combines the payment gateway and payment processor of banks/acquirers, as well as the functions of risk management systems and acquirers. This makes CodePay a full stack payment service provider. Merchants can quickly and safely use global payment services by integrating CodePay's payment capabilities.
