Checking payment status

The easiest way to check payment status is the merchant dashboard.

1. Go to

   /dashboard

   (e.g.

   https://zynpay.com/dashboard

   in production).
2. Connect your wallet (the same wallet you used as the merchant when creating links).
3. You'll see a Payments table with:
   • Date / time
   • Description (from the payment link)
   • Amount (USDC)
   • Status
   • Transaction hash (link to Basescan)

If you generate links from your own app, you can keep a simple record like this:

// When you create a payment link:
const paymentLink = createPaymentLink({
  merchant: "0xYourWalletAddress",
  amount: 50,
  description: "Invoice #123",
});

// You store something like:
{
  id: "invoice_123",
  link: paymentLink.url,      // e.g. https://yourdomain.com/pay?p=...
  amount: 50,
  status: "pending"
}

Later, you:

• Open

  /dashboard

  to see whether that invoice is paid.
• Or use the SDK to check status programmatically (see below).

From the dashboard you can click the transaction hash to open a block explorer.

// Example: verify a tx from your dashboard
const txHash = "0x1234...";

// Base Sepolia:
https://sepolia.basescan.org/tx/0x1234...

// Base Mainnet (when live):
// https://basescan.org/tx/0x1234...

On the explorer you'll see:

• ✅ Transaction status (Success / Failed)
• 💸 Amount of USDC transferred
• 🧾 Fee split (merchant share vs platform fee)
• ⛓ Block and confirmation count

If you're a bit technical, you can fetch the same payment history that powers the dashboard using the SDK.

import { ZynPayClient } from "@zyntrialabs/zynpay-sdk";

const client = new ZynPayClient({
  merchantWallet: "0xYourWalletAddress",
  environment: "testnet",
});

const payments = await client.payments.listPayments();

for (const p of payments) {
  const amount = Number(p.amountTotal) / 1e6;

  console.log("Payment:", p.paymentRequestId);
  console.log("Amount:", amount, "USDC");
  console.log("TX:", p.txHash);
}

You can use this to:

• Build your own dashboard
• Sync payments into your backend
• Export to CSV for accounting

For more details, see the TypeScript SDK and Python SDK reference pages.

If you need to refund a payment:

• Refunds are initiated by the merchant wallet.
• They send USDC back to the payer via the ZynPay router.
• The smart contract guarantees you can't refund more than the original amount.

Typical flow:

1. Find the payment in the dashboard.
2. Click Refund (or use your own admin UI).
3. Confirm the refund transaction in your wallet.
