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 need to ensure that your outputs meet Alipay+ standards, such as logos displayed on payment terminals and payment receipts. For more information about the requirements, see Standard output checklist.
• 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.
