recently found online asked more and more people on the support of the interface, most people have some skills in the program, but very confused on the online payment interface, a lot of the time I do not know where to start. In fact, no matter what kind of payment interface, the principle is the same, just know that a payment interface usage, other interfaces can be derived, the different parameters of each own transfer may be just not the same.
first, we take the Alipay interface, Alipay interface documentation has more than and 10 pages, the initial contact may see the head is dizzy, but I still don’t know where to start. In fact, the more than and 10 page content just made the following points: to implement the interface you have to have a website, have a Alipay account, Alipay cooperation identity ID, security check code etc.. To achieve a simple function of the payment, in fact, only a few files configure Alipay interface folder on it. Take the ASP version of the interface to explain, the more easy to understand: there is a alipay_Config.asp on the inside of the configuration set up your information, attention is notify_url return_url with two variable function. The configuration of the two pages of Alipay_Notify.asp and return_Alipay_Notify.asp means that you can change the state of your database from the content of the page to determine if the customer is paying for it,
