Synchronous return process (return_url): is a visual return, ie the page jump notification, as long as the successful payment, Alipay jump to get this address by the way, and with parameters for this page. Customer access to information affected buyers operations. If the buyer paid after the completion of the client server response is slow, buyers Close when displaying Alipay prompt "payment successful Instant Credit", then the customer site is to get less information, we here called "single out." And the return process is a one-time retrieval of that payment after the successful retrieval of synchronous return process.

Asynchronous return process (notify_url): its data exchange is exchanging data through inter-server, it must be placed on the server (public network) test server post message to the asynchronous process returns page, customer needs technical process returns page processing asynchronous related to data processing, and each step must be returned to the Alipay success (not contain other HTML scripting language, do not jump page.) If this returns processing integrated OK, so basically will not be out alone, because the payment will treasure points within 24 hours of the order of 6 to 10 times more information back to the customer site, Alipay until the capture success.
