A must-have for anyone looking to become an expert in application programming interface (API) developer, tester, integrator, or manager; this revised and updated edition of "Mastering Postman" covers every aspect of API development, including the noteworthy new features of Postman 11.

In this all-inclusive book, developers of all skill levels will find modern methods and best practices that cover every stage of the API lifecycle. This book provides a solid grounding in API design, documentation, and implementation, starting with the basics of Postman 11. Using Postman's most recent features, you'll learn the ins and outs of automated testing, error handling, and real-time monitoring—all of which are essential for APIs. It focuses mostly on the updated features of Postman 11.

This version discusses the new scripting features that enable more complex testing scenarios, as well as the improved integration options that make connecting to other platforms and services easier than ever before. Also covered is the latest Postman CLI and how to use it to automate and improve API testing and deployment in CI/CD pipelines. It also covers Postman's real-time collaboration features helping API teams collaborate more efficiently. You will also find out how to use Postman's new performance testing features, such as advanced load testing, to make sure your APIs can manage actual user traffic.

Key Features

• Manage the entire API lifecycle, from planning to development, testing, and release.
• Automate complex API tests with Postman 11's improved scripting capabilities.
