APM - Non-Periodic Auto Debit Integration ​

This document describes the relevant integration steps for non-periodic auto debit, specifically including: binding the payment method, obtaining the result of binding the payment method, initiating the direct debit, and obtaining the direct debit result, etc.

1. Preparation Items ​

According to the guidance in "Configuration and Signature" , obtain the merchant self-service platform account, obtain the merchant appId and secret key, configure the asynchronous notification address, and configure the public key and private key.

2. Interaction Process ​

3. Auto Debit Rules ​

  • Merchant auto debits can be divided into the first deduction and subsequent direct debits; the first deduction requires the user to bind the payment method, and subsequent direct debits are deductions initiated by the merchant, and the user does not need to participate in the deduction process;

  • For the first deduction, the Payment Cashier mode, API mode, and Pre-component mode are supported for integration; for subsequent deductions, the user does not need to participate, and only the API needs to be used to complete the deduction;

  • For the first deduction, the transaction amount (totalAmount) supports 0 yuan and specific amounts greater than 0 yuan; if the transaction amount is 0 yuan, it means only binding the payment method; if the transaction amount is greater than 0, it means initiating the payment and binding the payment method; after the transaction is successful, PayerMax will generate a token (paymentTokenID) for the user's payment method and notify the merchant, which is used for subsequent direct debits;

  • For subsequent deductions, providing the paymentTokenID to replace the user's payment method can complete the deduction.

4. Binding the Payment Method ​

Core parameter description:

  • totalAmount: The transaction amount, which supports passing 0 or an amount greater than 0;

  • paymentDetail.mitType: The auto debit type, SCHEDULED indicates periodic subscription, and UNSCHEDULED indicates non-periodic auto debit;

  • paymentDetail.tokenForFutureUse: true/false, whether to generate a token for subsequent direct debits; when binding the payment method for the first time, this value should be passed as true;

  • paymentDetail.merchantInitiated: true/false, whether it is a transaction initiated by the merchant; when binding the payment method for the first time, the user needs to participate in completing the authentication or authorization, and the value should be passed as false.

4.1 Binding the Payment Method Using the PayerMax Payment Cashier ​

Note:

The cashier mode binds the payment method to support Full cashier mode, Specify payment method, and Specify payment method + target institution.

For the interface document of binding the payment method in the Checkout mode, please refer to the Checkout - Place Order API. The request addresses for different environments are as follows:

When the full cashier transaction amount is greater than 0, the request parameter example is:

4.3 Binding the Payment Method Using the Front-end Component ​

Note:

The Drop In mode does not support wallet payment methods, only card payment methods are supported to activate subscription plans.

For binding the payment method using the front-end component, the merchant needs to complete the integration through two steps. For details, please refer to: Integration Process.

When binding the payment method using the front-end component, the merchant's server needs to call two API interfaces provided by PayerMax: Apply Drop-in Session API and Front-end Component Payment API. The request addresses of the Apply Drop-in Session interface in different environments are as follows:

Example of Input Parameters for the Apply Drop-in Session Request:

5. Obtaining the Result of Binding the Payment Method ​

Merchants can receive the result of binding the payment method through the notifyUrl address provided when binding the payment method. For the detailed result message, please refer to: Result Notifications API.

Example of notification parameters for successful binding of the wallet payment method:

json
{
    "appId": "d68f5da6a0174388821a64114c6b322c",
