Testing REST APIs with Swagger and HTTPie

Web browsers are designed for displaying web pages to humans, not for communicating with raw application interfaces. To develop, test, and debug modern web applications, you need dedicated tools to interact directly with REST APIs. This text-only guide teaches you how to efficiently test and debug APIs using Swagger and HTTPie. You will learn to navigate API documentation, send structured requests, and analyze responses without writing complex testing scripts. What you'll learn: 1. Understand the fundamentals of HTTP methods, status codes, and REST architecture. 2. Explore and test endpoints interactively using Swagger UI and OpenAPI specifications. 3. Construct and execute precise API requests from the terminal using HTTPie. 4. Manage modern authentication flows, including Bearer tokens and API keys. 5. Analyze JSON payloads, headers, and query parameters to debug application behavior. The course begins with foundational API concepts and key terminology, then moves step-by-step through interactive Swagger documentation and hands-on terminal testing with HTTPie. Designed for beginner developers, QA testers, and tech enthusiasts looking to master API interaction, this course requires no previous API testing experience.
