REST API Development – Build, Test, Troubleshoot

Unlock the full potential of backend development with “REST API Development – Build, Test, Troubleshoot”. This comprehensive course is designed to equip you with the essential skills required to create powerful and efficient RESTful APIs from scratch.

You’ll begin by understanding the core principles of REST architecture and HTTP methods, then move on to building real-world APIs using popular frameworks like Node.js with Express or Python with Django REST Framework (customizable based on the tech stack). Learn how to structure routes, handle requests and responses, and implement authentication and error handling for production-ready APIs.

But building is just the beginning—this course dives deep into API testing using tools like Postman and Swagger, as well as automated testing frameworks to ensure your endpoints are reliable and bug-free. You’ll also gain hands-on experience in debugging and troubleshooting common API issues, such as CORS errors, latency problems, invalid responses, and integration failures.

Whether you’re a junior developer looking to solidify your knowledge or a professional wanting to improve your API toolkit, this course offers practical exercises, project-based learning, and step-by-step guidance to get you confident in developing and maintaining RESTful services.

What You’ll Learn:

• RESTful architecture and best practices

• Building APIs with Express, Django, or other frameworks

• Input validation, middleware, and authentication

• API testing using Postman, Swagger, and Jest/PyTest

• Troubleshooting real-world issues and performance tuning

• Versioning, documentation, and deployment tips

By the end of the course, you’ll have built and tested your own API, diagnosed and fixed errors, and understood how to maintain robust, scalable systems in a professional development environment.
