Note : This is the latest version of the Auto Debit documentation. The previous version will not be updated anymore but will still be available until September 2022, after which it will be deprecated and removed from Alipay Docs.

Auto Debit is a payment solution that allows merchants to make pre-authorized fund deductions from a user's account. The user gives consent to a merchant via a payment agreement, such as the three-party withholding agreement. When the user purchases items on the merchant's site, the merchant can deduct funds from the user's account directly by using an authorization token.

User experience

The authorization process can be initiated via a website, WAP page, or mobile phone app. This video shows the authorization experience for these terminals.

To understand the complete user experience for authorization and see sample process flows between the merchant and payment method, see User experience .

Figure 1. Integration procedure

To integrate in the sandbox and then go live, it is suggested to follow these steps:

Read Best practice to understand the API interaction logic so that you can improve the integration efficiency and avoid payment disputes. All APIs and SPIs provided for Auto Debit are displayed in the APIs and SPIs section.
Integrate the product functionalities listed in Product functionalities . When using APIs to integrate, you need to make a POST request to the corresponding address with the identity information, signature, and business parameters in the HTTP request. After receiving the request, Alipay verifies the signature of the request. If the signature verification is passed, Alipay returns the corresponding response to you. After your server receives the response, you also need to verify the signature of the response to check whether the response is sent by Alipay. If the signature verification is passed, you can take further actions in your system. These topics will help you tackle problems that you might encounter when calling the APIs:

Use test payment methods and accounts to simulate real scenarios in the sandbox. When creating and debugging the application in the sandbox environment, remember to use Alipay-provided tools to facilitate the integration process.
Once you have completed the go-live tasks, use the real payment method app and live account to conduct pilot testing. Contact Alipay Technical Support if you need help creating a live payment method account. Ensure your applications are running smoothly end-to-end by performing production test cases in the production environment with the live account.
