[Arthur · Rating 5 out of 5]

These days, APIs are ubiquitous, nevertheless, it is still difficult to discover their usage, capabilities and test them without a specialized tool.
For many in the IT industry, it is hard to think of a more proliferated tool for the APIs testing and exploration than Postman.
So why not to leverage it to its full potential and rip maximum benefits?
This book is focused exactly on this.
For myself, a daily user of Postman, many areas of remained obscure and hardly visited.
This book broke into these areas guiding gently and affirmatively toward various useful goals of an IT practitioner (be it a developer or QA analyst).
I liked how the author sets the stage in the book so it becomes easy for even a novice to approach APIs.
The most useful parts of this book for me were on creating mocks, test automation and integration with CI.
What remained uncovered, but I wished was fleshed out are the paid parts as working in teams (e.g. collaboration), cloud integration, flows, etc.
Still a solid five.
Fasten your belt and become more efficient and productive testing and developing APIs!
