For developers, programmers, and DevOps engineers venturing into the hard world of API development, the "Postman Cookbook" becomes a must-read. This short solutions book offers recipes and troubleshooting approaches to address typical API lifecycle management challenges. Using Postman's rich features, readers of all skill levels will learn how to create APIs that will improve workflows, increase productivity, and lead to operational success.

The book covers a wide range of topics, from the fundamentals of web-based communication to more complex topics including protocol stacks, secure communication protocols, and the dynamics of WebSockets interactions. The following sections cover advanced subjects such as custom protocol handling, network troubleshooting, and proxy management, allowing readers to confidently solve complex networking challenges. This book covers more than simply the technical aspects of Kubernetes. It discusses the influence of security measures, maximizing performance, and successful scaling solutions. These features are critical for microservice architectures and cloud-native apps. This book teaches early developers and programmers the foundations of API testing and development, including networking and protocols.

Key Learnings

• Enable real-time API connectivity for dynamic apps using WebSockets capability.


• Protect API endpoints from security flaws by configuring SSL/TLS in Postman.
