I create a campaign titled A5 Coupon with a total of 6,000 pounds and generate unique coupons for it. I show the redemption process, including handling duplicate requests and testing failure scenarios with invalid coupons. I also run a reconciliation API to ensure data consistency. The wallet balance for the user is confirmed at 6,060,005. Thank you for watching.
