Postman API Testing | Step by Step for Beginners

Raghav Pal introduces API concepts before using Postman to create requests and organize collections. A local REST API provides a practice target, while variables, environments and later automated execution connect the desktop workflow with repeatable tests. It suits beginners who want to understand the meaning of a request before adding scripts or relying on a shared collection created by someone else.

What you will learn

• Learn API basics and create a local REST target.
• Organize requests, collections and environments.
• Explore command-line and Jenkins execution.

Who this suits

Beginners; existing API or Postman knowledge is not required. The page was updated in November 2025 and lists about eight hours and thirty-nine minutes of video, with additional practice needed.

Before you enroll

Practice against a local or explicitly permitted API with fictional records. Keep tokens and credentials out of shared collections, repositories, screenshots and exported request logs. Match examples with the current Postman interface and plan limits; cloud collaboration or other tools may cost extra. A successful response is only one test outcome: consider invalid input, permissions and repeatable execution before relying on a collection.

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

Put it into practice

Create a local fictional API and a small Postman collection for it. Use an environment variable for the base address, test one invalid request and explain how the collection could run without manual editing.
