Wechatpay Product Coupon

wechatpay-apiv3/wechatpay-skills

This is a comprehensive integration guide for WeChat Pay's product coupon system. It walks you through the entire lifecycle: selecting the right coupon type from 10 options, generating signed API code examples in Java and Go, handling callbacks and refunds, and debugging specific error codes via Request-Id. What stands out is the structured troubleshooting approach and the insistence on step-by-step user confirmation before executing anything, which prevents the common pitfall of making assumptions about your setup. Supports both direct brand integration and service provider modes. If you're building coupon features for WeChat Pay in China, this covers the integration checklist and common gotchas in one place.
