Overview

EasyPay Subscription Payment is a service that allows merchants to process payments at desired intervals (e.g., subscription services, regular deliveries) based on a Billing Key issued through a customer authentication process. The overall process of subscription payment is as follows:

When a customer selects a subscription product, the EasyPay registration page opens. After the customer registers their credit card, the merchant issues a customer-specific Billing Key. Subsequently, the payment approval API is called via a Server-to-Server connection according to the merchant server's scheduling logic.
