Project Specification: Payment Integration Endpoint
Objective: Develop a backend system that enables customers to make payments using credit cards, WeChat Pay, Alipay, and QR codes. The system will log transactions in DynamoDB, verify order accuracy via a cost calculation endpoint, and be implemented using Python 3.12 on AWS Lambda, managed with the Serverless Application Model (SAM).
