How to Verify UPI Payments Using Webhooks

Never trust a browser callback alone. Webhooks should be authenticated (signatures or shared secrets), replay-safe, and processed idempotently so duplicate events do not double-ship goods.

Checklist

• HTTPS endpoints with valid TLS
• Timestamp and nonce where provided
• Persist raw payload for audits
• Return 2xx only after durable DB commit

VyaparGateway emits structured events you can verify server-side—see API docs after login. VyaparGateway helps you issue dynamic UPI QR codes, verify payments, and notify your stack via webhooks—without charging a per-transaction platform fee on top of your plan.
