Integration

Merchants want to integrate the payment flow on their cashier page, PayerMax provides Direct API access.

For the Direct API interface, merchants need to have PCI-DSS certification if they process card number information by themselves.

1. Integration Steps

The user enters payment information on the checkout page and calls the Direct API interface to complete the payment.

2. Order Repeat Check

When a merchant submits a Direct API request, the submitted order number must be unique. If PayerMax recognizes that the merchant is requesting with the same order number, it will reject the request and return: Duplicate order.

3. Response Scenarios

The transaction status of Direct API access is divided into the following scenarios:

(1) Complete the payment online, please update the transaction result according to【Transaction Status】in the response, and do not update the transaction result according to the code and message.

(2) Redirect to wallet/bank/3ds authentication, the response contains redirectUrl, please update the transaction result according to【Callback Notification】
