Building and Testing REST APIs with Spring Boot and Postman

Creating reliable backend services is a core skill for modern software developers, but building them is only half the battle—you must also know how to test them effectively. This text-based course guides you through the entire lifecycle of API development, from initial design to automated testing. You will transition from a beginner to a confident developer capable of constructing robust RESTful endpoints and validating their behavior. Through structured explanations and clear code examples, you will learn how to handle data, manage HTTP methods, and structure your backend applications using modern industry standards. What you'll learn: Learn the fundamental principles of REST architecture and HTTP communication protocols. Build structured Spring Boot applications with controllers, services, and repositories. Configure Postman environments, collections, and variables to streamline your testing workflow. Apply modern error-handling techniques using standardized problem details for HTTP APIs. Practice writing automated API test scripts within Postman to validate responses and status codes. Understand how to connect your APIs to a database and perform standard CRUD operations. The course begins with essential API concepts and foundational Spring Boot setup before moving into hands-on endpoint creation and database integration. You will then progress to advanced Postman testing workflows, ensuring your APIs are reliable and ready for production. This course is designed for beginning developers, students, and software engineers looking to gain practical API development and testing skills. No prior experience with Spring Boot or Postman is required, though a basic understanding of Java is helpful. Start reading today to master the essentials of API development and testing.
