RESTful Web Services: Fundamentals and Modern API Design

Modern web applications rely on seamless communication between distributed systems. Understanding how to design and interact with RESTful services is a foundational skill for any aspiring web developer. This text-based course guides you from the absolute basics of distributed computing and service-oriented architecture (SOA) to the practical design of modern RESTful APIs. You will gain a deep conceptual understanding of how the web works and learn to structure APIs that are scalable, maintainable, and secure. What you'll learn: - Understand the core elements of distributed computing and service-oriented architecture (SOA). - Master the foundational constraints of REST, including statelessness, uniform interfaces, and cacheability. - Design resource-oriented APIs using standard HTTP methods, status codes, and URI structures. - Apply modern API practices such as token-based authentication and payload formatting with JSON. - Explore API documentation standards using modern OpenAPI specifications. - Practice modeling API resources and handling errors through structured written exercises. You will start by exploring the history and key concepts of distributed systems before diving into the core architectural constraints of REST. From there, the course guides you through practical URI design, request/response lifecycles, and modern API security patterns through clear, written explanations and code examples. This course is designed for beginner web developers, software engineering students, and anyone looking to understand the mechanics of modern web APIs. No prior experience with API design is required.
