The so-called application programming interface API is its abbreviation. My first impression was that an API of Windows API started screaming. The window library provides a series of functions that you can use to apply to Windows programming.

Is the API interface of your website available to others? Your website needs someone to do it. Can it be redeveloped? I want to be alone. You should use some functions on the right side of your website to remember. For example, you can allow others to provide an account, and you are not here to confirm that this account belongs to you.

In my opinion, you will be able to provide HTTP, actually PHP pages and return XML. You have developed a protocol, such as what kind of data to provide to others, the results you return, and any errors and correct returns. . .
