Postman API Testing Portfolio: Library Management System

🚀 Project Overview

This repository contains a comprehensive Postman collection developed to demonstrate advanced API testing and automation capabilities. It covers the full CRUD lifecycle for a Library Management API.

• Automated Test Scripts: Developed JavaScript-based Post-response scripts to dynamically capture data (like bookId) and pass it between requests.
• Environment & Collection Variables: Engineered a flexible testing environment using variables for baseUrl and authentication keys.
• Complex API Workflows: Configured a sequence of 8 requests including GET (filtering), POST (data creation), PATCH (partial updates), and DELETE.
• Troubleshooting: Successfully debugged and resolved 401 Unauthorized and 500 Internal Server errors during the development phase.
• Authentication: Implemented Header-based API Key security protocols.
