Alipay Developer Center

The Alipay Developer Center helps you integrate with Alipay products. This section provides information about how to use the Alipay Developer Center to perform the self-integration process. If you face issues with logging in, contact Alipay Merchant Technical Support.

Note: Before you start the integration process, ensure that you have already signed the contract with Alipay products. If you have not signed the contract yet, contact Alipay Merchant Business Support for the relevant process.

Integration process

Integration with Alipay products via Alipay Developer Center consists of the following steps:


Figure 1. Integration process

Step 1: Register & log in

Register on the Alipay Global Merchant portal to become an Alipay business partner. Then, get your Alipay account to log in to the Alipay Developer Center to start your integration process.

Note: The account for logging in to the Alipay Developer Center needs to be the same account as the one used in the signed Alipay contract.

Step 2: Become a developer

After you log in to the Alipay Developer Center, read and agree to Alipay Developer Terms of Use. Then specify your role to set the integration mode.

Types of roles:

  • Merchant: Use this role if you are a merchant that is making the integration for your company in-house.
  • Acquirer: Use this role if you are an acquirer that is making the integration for your company in-house. An acquirer is an institution that processes payments on behalf of Merchants.
  • System Integrator or Independent Software Vendor (ISV):

Use this role if you are one of the following roles:

    • A merchant who is outsourcing the integration to a system integrator.
    • An ISV that has signed a contract with Alipay to provide integration services for merchants.


Figure 2. Specify the role

Once you have completed the above steps and have successfully completed the onboarding process as an Alipay developer, read the Quick Start guide to familiarize yourself with the upcoming steps and click Get Started to continue.

Step 3: Create application & select product

Create an application on the home page of Alipay Developer Center and provide basic information about the application, such as the application name, application type, business registration country/region, and application description.

Please choose carefully as the business registration country/region determines Alipay integration settings, and this cannot be changed later in the integration process. For example, choose Singapore if you are an ISV in Singapore.


Figure 4. Enter application information

Select the product and scenarios to integrate with and specify the test currency. Each application supports only one product and one test currency. However, multiple scenarios of one product can be supported. If you want to integrate with more than one product, you need to create several applications.


Figure 5. Select the product and scenarios

After creating the application, you can check your Client ID and other related information about the application on the Basic Information page:


Figure 6. Check the application's basic information

You can also see all the created applications and their corresponding statuses on the home page of Alipay Developer Center.

Step 4: Receive sandbox resources

After creating the application and selecting the product, sandbox resources are automatically allocated to you. You can check the sandbox resources on the Sandbox page. Sandbox resources include:

  • Sandbox Client ID
  • Buyer account and password of the Alipay China wallet.
  • Merchant account


Figure 7. Sandbox resources

For ISV, after creating the application, you can view your development information used in the production environment and the sandbox environment, such as gateway endpoint, client ID, test token, ISV client ID, ISV customer ID, and test merchant customer ID.

In the sandbox integration, a testing merchant is provided to you to perform the needed integration with Alipay API. Understand the following ID and token definitions before proceeding:

  • ISV customer ID: The internal MID assigned for the ISV.
  • Client ID: The client ID assigned for the ISV.
  • Customer ID: The internal MID assigned for the test merchant.
  • Test token: The corresponding authorization token for a test merchant, which is used in the sandbox.
  • Authorization token: The token used to identify the merchant when calling Alipay API. This is generated by Alipay when the merchant authorizes you as an ISV.

Step 5: Configure in sandbox

On the Integration Settings page, you can check your sandbox Client ID, configure sandbox keys, and set the gateway URL.

To make your integration safer, Alipay uses asymmetric keys. You need to upload your public key on Alipay Developer Center to get the Alipay public key.

Step 6: Test in sandbox

After configuring in the sandbox environment, you need to develop and integrate with Alipay services in the test environment. A production environment is simulated with the sandbox resources you obtained in step 4. Integrating with the test environment consists of the following parts:

  • Calling APIs
  • Processing reconciliation files
  • Testing and acceptance

For more information, see Integration Guide.

For the sandbox integration, the Agent-token should be set to the provided test token. During the sandbox integration, Alipay generates the reconciliation files on behalf of the test merchant, not the ISV. We recommend that an ISV validates whether the reconciliation files created for the test merchant of the transactions are correct. See Reports and reconciliation for details.

Step 7: Go live & launch

Once you have completed tests in the sandbox and are ready to go live, you can enter the Integration Settings page, click on the Live tab, and make the following configurations:

  • Get your production Client ID on the page.
  • Set your public key and then get the Alipay public key. The keys are to be used for signing the request and verifying the signature after the application rollout.
  • Set the gateway URL for the production environment.


Figure 12. Configure the production environment

After configuring for the production environment, you can launch your application by clicking the Launch button.

As an ISV, in addition to following the integration guidelines, you need to set the Agent-Token header as described in the Alipay API specification for each API call with an authorization token. The token is necessary for Alipay to identify the merchant you serve.


You can only launch an application after you have signed the business contract with Alipay. If you need to modify configuration details, such as the public key or notification URL after the application has launched, email verification is needed.


Figure 13. Launch the application

ISV integration

ISV needs further actions after completing all the above steps in integration.

Step 1: Share authorization URL with merchants

This step is only required for ISVs. Once your application is launched to live, merchants can onboard. In Alipay Developer Center, you can manage existing authorized merchants under Application Authorization. You can generate your specific authorization URL by clicking Generate Authorization URL, and share it with merchants that authorize you as an ISV. If your application is not launched to live, this button is disabled.


Figure 14. Generate authorization URL

Step 2: Be authorized by merchants

Merchants who use ISVs to integrate with Alipay still need to be onboarded with Alipay through Alipay's customer service agents via a similar back-office system.

Once the vetting is completed, merchants can visit the given authorization URL to authorize the ISV to perform integration on their behalf. This completes the setup among ISVs, merchants, and Alipay.

Merchants can use the same registration email provided during the vetting process as the account. If it is the merchant's first login, click Forget password to set up the password and log in.

Step 3: Obtain the authorization token

After merchants complete the authorization, you can view the authorization token under Application Authorization in Alipay Developer Center.


Figure 15. Obtain the authorization token

Alipay generates the authorization token when merchants authorize you as an ISV. This token is set in the Agent-Token header and is used to identify the merchant when the merchant calls the API.

You can also check authorization-related statistics under Basic Information.
