What makes a good API is with the design process and design principles

Main Effects:

The main purpose of the API is to provide users and developers with the ability to access a set of routines without having to access the source code or understand the details of the inner workings. Software that provides the functionality defined by an API is called an implementation of the API. An API is an interface, so it's an abstraction.

What does it mean to encounter an API interface when you are a beginner in programming?

An API interface is an operating system or program interface, while the latter two are direct user interfaces. Sometimes companies use APIs as their public open systems. In other words, the company develops its own system interface standard, through which all members of the company can invoke the source** when it is necessary to perform operations such as system integration, customization, and program application, which is called an open API.

Due to the major adjustment of third-party policies, the industry has gradually tightened, and more and more people in the market need interfaces, and there is no way to easily apply for interfaces when they need interfaces, so API interface programs came into being to solve the problem.

After the API interface is connected to the third-party interface, the interface can be developed infinitely, which is suitable for many industries.

To put it simply, the API interface is a new online payment program that integrates all payment channels on the market and provides partners with multi-channel channels to achieve resource sharing and risk sharing.

Ensuring security can be done in three ways: Authenticate the client Encrypt sensitive data and prevent tampering Authorization after authentication Now it is more popular to use the OAuth protocol for identity authentication.

A good RESTful API should have the following characteristics: The API should be browser-friendly and integrate well into the web, not be out of tune with it. 1.

Browsers are the most common and versatile REST clients. A good RESTful API should be able to do all the testing using browser + HTML (no programming language required).

If the landlord still doesn't know, then go here and have another look.

What does it mean to encounter an API interface when you are a beginner in programming?

An API simply means an "application programming interface".

You can call a variety of APIs that have been written by others to achieve the purpose of use, such as: calling existing components, calling WIN components, calling hardware ......Wait, these are written by someone else, you can call it. Alternatively, you can write your own API

I don't know how to say that, is it easy to understand?
