What is WeChat Pay Full-Stack Skill?
The WeChat Pay skill is designed to bridge the gap between complex official APIs and practical developer implementation. It allows users to trigger payment QR codes by simply providing non-sensitive data like order IDs and merchant IDs, while the system handles sensitive operations such as API key management, RSA signing, and platform certificate validation behind the scenes.
By leveraging Openclaw Skills, businesses can streamline the entire payment lifecycle—from initial merchant onboarding and JSAPI/Native interface integration to daily operations like reconciliation and refunds. The skill enforces strict security protocols, ensuring that sensitive credentials are never exposed to end-users or recorded in logs.
WeChat Pay Full-Stack Skill Use Cases
- Automating the generation of Native payment QR codes for physical stores or desktop websites.
- Integrating JSAPI payments within WeChat Mini Programs or Official Accounts.
- Streamlining daily financial operations such as downloading transaction bills for automated reconciliation.
- Handling secure refund requests and processing cashback marketing campaigns via red envelopes.
- Simplifying the merchant onboarding process with guided official documentation links.
How WeChat Pay Full-Stack Skill Works
- The user provides public parameters such as the Order Number and Merchant ID to the AI agent.
- The system retrieves pre-configured sensitive credentials (API keys, private keys) from a secure management vault.
- A request is sent to the official WeChat Pay API using automated signing and encryption mechanisms.
- For Native payments, the system receives a code_url and converts it into a scannable QR code image for the user.
- The skill monitors asynchronous callbacks from WeChat servers to verify payment success via HTTPS.
- Upon verification, the system updates the local order status and notifies the user of the completed transaction.
WeChat Pay Full-Stack Skill Setup
The deployment requires administrative configuration of official WeChat Pay credentials.
# Example: Verify your merchant configuration environment
# Sensitive keys are managed by the administrator, not the end user.
openclaw skill install wechatpay
# Configure secure environment variables (Admin only)
export WECHAT_MCH_ID="your_merchant_id"
export WECHAT_API_V3_KEY="your_secure_v3_key"
