REST API Testing with Postman: Practical Hands-On Course

Aliaksandr Khvastovich connects REST concepts with practical Postman requests and response analysis. HTTP methods, status codes and API documentation give the tests a clear contract, while manual and automated work provide different ways to inspect it. The course is useful for learners who want to explain why a response is correct, including its data and permissions, rather than check only that a request succeeded.

What you will learn

• Interpret an API contract and HTTP response.
• Use Postman for manual and automated checks.
• Test a documented endpoint against an explicit expectation.

Who this suits

Basic JavaScript is helpful for following the QA-focused examples. Review HTTP vocabulary and the test environment before sending requests.

Before you enroll

The page was updated in September 2024. Postman interfaces and account features can change. Use an authorized test API, isolate learning credentials and distinguish a successful status from complete validation of response behavior.

Udemy offers paid purchase or subscription access depending on the course and region. Paid teaching courses provide completion certificates under Udemy’s policy. Check current enrollment terms and any separate software, account or materials costs.

Put it into practice

Create a small collection with valid, invalid and unauthorized requests. Assert a meaningful response property, inspect a deliberately broken example and explain what the collection still does not cover.
