        type: 'payment',
        transaction_id: transactionId,
        amount: transaction.amount,
        currency: transaction.currency
    };
    
    // Use QR library to generate visual code
    const qr = new QRCode(document.getElementById('qrcode'), {

  • ✅ Handle malformed links gracefully
  • ❌ Don't execute code from deep links

Push Notification Security

  • Test with real but minimal transactions
  • Monitor all test transactions carefully
