WalletConnect Pay — Merchant Integration

Goal

Help developers create USDC payment requests using the WalletConnect Payment API. The integration enables merchants to generate payment links (and QR codes), send them to customers, poll for payment status, and retrieve transaction history. Customers pay from any WalletConnect-compatible wallet.

When to use

• Creating USDC payment requests from a server, web app, or React Native app
• Building a mobile POS terminal or payment kiosk with React Native
• Generating payment links or QR codes for customers
• Polling payment status (pending → processing → succeeded)
• Fetching merchant transaction history
• Integrating payment acceptance into a backend, dashboard, bot, or mobile app
• Troubleshooting merchant API authentication or payment creation errors
