🔗 API Chaining – CRUD Operations (Restful Booker)

This project demonstrates API Chaining for CRUD operations using the Restful-Booker API.
API Chaining means using the response of one API as input for the next, mimicking real-world workflows like authentication → create → read → update → delete.

---

🚀 Features Covered

• Authentication – Get access token
• Create – Create a booking and capture bookingid
• Read – Retrieve booking details using bookingid
• Update – Modify booking using bookingid + token
• Delete – Remove booking using bookingid + token

---

🛠️ Tech Stack

• Postman – API Testing & Chaining
• JavaScript Tests – Postman test scripts for validation
• Environment Variables – Store token and bookingid dynamically
• REST API – Restful-Booker

    participant U as User
    participant A as Auth API
    participant C as Create Booking
