The merchant could not attach parameters to the "return_url" and "notify_url", and hoping them be passed by Yedpay.
After program is executed, the page must print "success" (Alipay and Alipay Online) (without quote). (e.g. using die('success') in PHP)
If not, Yedpay server would keep re-sending notification, until over 20 minutes Generally, there are 4 notifications within 5 minutes Frequency.
Make sure the Notification Page notify_url is absolutely blank, only with "success" text in the body, without space, html tag, or any error message threw from the program system.
Only allowed HTTP and HTTPS ports (80 and 443) for notify_url
