Course description

REST API Development: Build Secure APIs from Scratch is a comprehensive course designed to teach you how RESTful APIs work at a fundamental level—independent of any specific programming language or framework.

In this course, you will learn the core concepts of REST architecture, HTTP methods, request–response handling, status codes, and API design principles that apply universally across backend technologies such as Node.js, PHP, Java, and Python.

Rather than focusing on a single framework, this course emphasizes API design thinking, security, validation, and best practices used in real-world production systems. You will understand how to structure APIs, handle errors properly, implement authentication and authorization concepts, and protect APIs against common security vulnerabilities.

The course also covers API testing using tools like Postman, versioning strategies, and deployment considerations. A reference implementation is used to demonstrate concepts practically, while clear explanations help you map the same logic to different programming languages.

By the end of this course, you will have a strong foundation in REST API development and the confidence to design and implement secure, scalable APIs in any backend technology of your choice.
