Stop clicking "Send" and hoping for the best - start testing your APIs like the pros do.
If you've ever manually checked an API response by eye, forgotten which environment you were pointed at, or shipped a broken endpoint because nobody re-ran the "old" tests, this book fixes that. Practical Postman takes you from your very first GET request all the way to a fully automated, documented, and monitored API test suite - the exact workflow professional API teams rely on every day.
You'll build real, working requests against real APIs from page one - no toy examples, no filler theory. By the capstone project, you'll have built the same kind of automated, production-grade test suite used at real companies, from scratch.
What you'll learn:
Building and organizing real GET, POST, PUT, PATCH, and DELETE requests
Debugging failed requests, CORS errors, and SSL issues
Using variables and environments to eliminate hardcoded URLs and tokens
Chaining requests and generating dynamic test data
Writing automated tests with pm.test and schema validation
Visualizing responses as readable tables and charts
Configuring API Key, Bearer, Basic, and OAuth 2.0 auth
Data-driven testing, mock servers, and published documentation
Automating everything with Newman and GitHub Actions
Part of the Practical Dev Tools series - real workflows, for tools developers actually use.
