Overview
The EasyPay Standard Payment Service allows customers to place orders through a merchant and complete payments after authenticating with external institutions (issuers/payment providers) via the payment window. EasyPay provides two types of payment services: one that calls the issuer's (including simple payment providers) window directly upon ordering, and another that calls them through the EasyPay-integrated window.
- Integrated Payment Window: A method where external institutions (card companies, simple payment providers, etc.) are called through the EasyPay-branded window.
- Supports credit cards, simple payments, virtual accounts, bank transfers, mobile carrier billing, and point payments.
- Offers features like interest-free installments or instant discounts during credit card checkout without separate inquiries.
- Standalone Payment Window: A method that directly invokes the external institution's payment window.
- Supports direct invocation of credit cards, simple payments, bank transfers, and mobile carrier billing.
- For credit card payments, separate APIs for interest-free installment inquiries and instant discount inquiries are provided.
The following diagram illustrates the standard payment flow:
When a customer completes authentication, they are redirected to the merchant's ReturnUrl along with an Authentication Transaction Number.
The merchant then uses this Authentication Transaction Number to request payment approval from EasyPay.
Once approval is complete, you can verify the final details from the response.
- To use the Multi-Settlement service, you must be issued a dedicated Multi-Settlement Merchant ID.
