    • If the merchant platform does not have an app or does not want to integrate an SDK, you can develop programming code with the payment URL.
  1. Handle the payment result that is obtained from Alipay+.

For payments that are processed by the AlipayCN wallet, customs declarations are required. In light of this, Alipay+ provides APIs for customs declaration. For more information about how to use these APIs, see Customs.

More information

Go through the section below to obtain more information that empowers your integration:

  • To ensure your integration with Alipay+ can work properly, you also need to ensure your merchant meets the requirements in terms of Alipay+ brand and integration. For more information about the requirements, see Requirements for merchants.
  • When using APIs to integrate, you need to take the following things into consideration:
    • Make a POST request to the corresponding address with the identity information, signature, and business parameters in the HTTP request. For more information about the structure of a request and response, see API overview.
    • To ensure the message transmission security, the ACQP must perform message signing and signature validation properly. When calling an Alipay+ API, the ACQP must sign the API request and validate the response signature accordingly; when receiving an API call from Alipay+, the ACQP must validate the request signature and sign the API response accordingly. For more information, see Sign a request and validate the signature.
