This book provides a cookbook of guidelines on designing beautiful (simple to use) and practical (simple to implement) RESTful API.

Which HTTP method should I pick for my API path? Look it up in the RESTful dictionary.

Much of API security boils down to how you handle identity. In Identity and APIs, we discover the techniques to secure platform access and delegate access throughout a mature API ecosystem.

Most asyncio tutorials introduce async and await on page one and ask you to take the runtime on faith. This book does it the other way around. You build a working event loop in thirty lines of plain Python — no asyncio import — and meet the keywords as labels for parts of a runtime you have already watched run. By the end, async Python stops being intimidating and starts being readable.

Become a Job-Ready API Automation Engineer Using PlaywrightAPI testing is now a must-have skill for modern QA engineers. Companies expect testers to validate backend systems, automate workflows, and integrate tests into CI/CD pipelines.This practical guide teaches you how to master API Testing using Playwright and TypeScript from scratch — even if you are transitioning from manual testing.In this book, you will learn how to:✔ Understand APIs, HTTP, and JSON from a tester’s perspective ✔ Write real API automation tests using Playwright ✔ Handle authentication, dynamic data, and environments ✔ Design a scalable API test automation framework ✔ Integrate tests into CI/CD pipelines ✔ Combine API and UI testing for faster automation ✔ Prepare for API testing and Playwright interviewsBy the end of this book, you will have the knowledge and confidence to build professional API automation frameworks and advance your QA career.Perfect for: QA Engineers, Manual Testers, Automation Testers, SDET Aspirants

We'll build an agent step-by-step, starting with a small loop that accepts input and produces structured output. As we go, we'll add tools, validation, model switching, runtime adapters, and packaging techniques that'll let the agent move from a simple script to a reusable application.

A step-by-step Playwright + TypeScript guide for manual testers or who wants to switch to becoming automation engineers.
