API Testing with Postman Mastery

Course Description

Modern software is powered by APIs. Ensuring these APIs are fast, secure, and reliable is critical. Our API Testing with Postman course transforms you from a manual tester into a technical validation expert.

You will master Postman, the world's most popular platform for API development and testing. We cover everything from basic GET/POST requests to complex test scripting with JavaScript. You'll learn to handle authentication (OAuth, JWT), manage environments, and automate your tests using Newman and CI/CD integrations.

This course is 100% hands-on. You will test real-world APIs, simulate server failures, and build comprehensive test suites that can be integrated into a professional development pipeline.
