A practical introduction to how APIs work, why they matter, and how to use them effectively in real projects.

This course starts with the basics of what an API is and how it fits into the wider world of Technology. You will learn how client-server communication works, what happens inside HTTP requests and responses, and how methods, endpoints, and status codes shape every API interaction.

From there, API Fundamentals moves into working with API documentation, understanding JSON and other common data formats, and making your first API call. You will also learn how to customize requests with query parameters and headers, handle authentication and API keys, and apply REST principles when thinking about API design.

The course then helps you go beyond the basics by covering pagination, filtering, sorting, error handling, versioning, and backward compatibility. You will also explore practical testing workflows, rate limits, reliability, and the best practices that make API integrations more dependable in real-world environments.

By the end, you will understand not just how APIs function, but how to use them with greater accuracy and confidence in real projects. You will be able to read documentation, send requests, diagnose problems, and work with APIs as a practical part of modern Technology.
