.NET Core Microservices - Demo - Calling Coupon Microservice

The video tutorial explains how to validate a coupon in a shopping cart application by calling a coupon API. It covers setting up the coupon service with dependency injection, creating a Coupon DTO, and modifying the card header to include additional properties. The tutorial also addresses debugging issues, such as missing configurations and incorrect object deserialization. Finally, it demonstrates how to display the discount and order total in the application, ensuring the coupon logic is applied correctly.

What is the initial step when validating a coupon in the shopping cart?

• Check if the coupon code is expired

• Ensure the shopping cart header is not null

• Verify the user's email address

• Calculate the order total

What is the purpose of adding the coupon service with dependency injection?

• To allow asynchronous operations

• To improve database performance

• To enhance the user interface

• To facilitate the retrieval of coupon data

Why are additional properties added to the card header DTO?

• To store user preferences

• To reduce API calls

• To include detailed order information

• To improve security features

What issue was identified during the debugging process?

• Network connectivity problems

• Invalid user credentials

• Missing coupon repository configuration

• Incorrect API endpoint

How is the order total adjusted after applying a coupon?

• By dividing the order total by the discount

• By multiplying the order total by the discount

• By subtracting the discount from the order total

• By adding the discount to the order total

What is displayed below the order total if a discount is applied?

• The original price

• The discount percentage

• The discount total

• The tax amount

What is a common debugging technique mentioned in the video?

• Adding breakpoints

• Rewriting the code

• Checking the API documentation

• Using print statements
