Integration
You can integrate with the Alipay system for a specific service. To use a specific service, you need to send an HTTP/HTTPS request to Alipay and use keys to sign the request before you send them. After receiving the request, the Alipay system verifies the request. If the verification is passed, the Alipay system responds the result data to you. For more information about sending an HTTP/HTTPS request, see Calling APIs. For more information about keys, see Preparing keys. For more information about processing the result data from Alipay, see Processing Notifications.
Before you start to integrate with Alipay, you can first download the Alipay demo code to get yourself familiarized with the payment process and make a test in the sandbox. For more information about demo code and sandbox, see Downloading demo code and Testing in sandbox. When you are ready, you can turn to production environment by referring to the information in Going live.
