Introduction

APIs are an important part of modern web and mobile applications. A well-designed API makes it easier for frontend applications, mobile applications, and other services to communicate with your backend.

Use Clear Resource Names

Use meaningful resource names such as /users, /articles, and /products instead of unclear endpoint names.

Use HTTP Methods Correctly

GET is commonly used to retrieve data, POST to create resources, PUT or PATCH to update resources, and DELETE to remove resources.

Return Appropriate Status Codes

Use HTTP status codes to clearly communicate the result of an API request. For example, successful requests may return 200 or 201, while client errors may return 400 or 404.

Validate Input

Never assume that data received from a client is safe or correct. Validate incoming data on the server before processing it.

Protect Your API

Authentication, authorization, HTTPS, rate limiting, input validation, and secure error handling are important parts of API security.

Conclusion

A good REST API should be predictable, secure, documented, and easy for other developers to consume.
