Project Overview

An Alipay Business Code payment backend service that helps merchants quickly integrate Alipay’s Business Code payment capability — covering the full flow from order creation, QR code scanning & payment, reconciliation, to order status callbacks. Ideal for chain stores, event registrations, self-service payments, and similar use cases.

Problems Solved

• Long development cycles and complex reconciliation logic when building custom payment integrations.
• Individuals and micro-merchants lack a unified, stable solution for payment collection and reconciliation.
• Integrating payments into existing systems requires frontend and backend modifications — resulting in high migration costs.

Use Cases

• In-person QR code payments: Fixed Business Codes used at physical stores or events for instant collection.
• Order system integration: Provides standardized payment and reconciliation capabilities for existing order management systems.
• Mini-program / web-based payments: Quickly generate payment orders and display QR codes on frontend pages.
• Automated reconciliation: Automatically notifies business systems upon fund settlement — eliminating manual verification.

Key Features

• Compatible with mainstream payment API styles — low migration overhead.
• Automatic polling-based reconciliation with high accuracy in settlement detection.
• Supports both legacy and new Business Code payment flows — flexible switching.
• Automatic order status callbacks — simple integration with business systems.
