HTTP Methods for API Testing and Automation

Every modern application relies on APIs to share data, but testing these interfaces requires a solid grasp of how web traffic flows. This course helps you break down the core protocols that power the web, enabling you to inspect, test, and automate API interactions with confidence. You will transition from manual testing concepts to structured API verification. By working through this text-only guide, you will understand how client-server communication works and how to construct precise API requests. You will learn to use command-line tools to send requests, analyze server responses, and verify application behavior. What you'll learn: - Understand core HTTP concepts, headers, status codes, and the request-response lifecycle - Master the primary HTTP methods including GET, POST, PUT, PATCH, and DELETE - Construct and execute API requests using curl syntax and options - Validate API responses by inspecting response bodies, headers, and status codes - Apply best practices for API testing, including error handling and security basics - Write basic scripts to automate API interactions and verify data integrity This course begins with foundational web concepts and terminology before moving into practical command-line examples. You will read through clear explanations, explore real-world request and response payloads, and practice writing commands to interact with test endpoints. This course is designed for beginners, aspiring QA engineers, and developers looking to understand the mechanics of APIs. No prior programming or testing experience is required.
