In easy-to-understand terms, an API interface is an encapsulation of a certain function. it can be encapsulated into a function or a service. for example, if a user places an order, I encapsulate the creation order as an API interface, therefore, mobile apps and PC websites all use the order API to create orders.
Any interface API has instructions, such as the payment API, you pass the order ID, amount, and other parameters. this interface helps you make the payment.

What API do you mean?

You can also regard a common page as an Api, which outputs html code.

Take A heap of parameter A and change it to another heap of parameter B.
Parameter A: {"username": chen, "age": 20}
Parameter B: {"status": "OK "}
