How to Accept USDT Payments on Your Website

Learn how to accept USDT payments on the TRON blockchain with Pulse2Pay's payment gateway. This guide covers everything from account setup to production deployment.

Prerequisites

Before you begin, you'll need:

A Pulse2Pay merchant account (sign up here)

API credentials (API Key and Secret)

A webhook endpoint on your server

Basic understanding of REST APIs

Step 1: Get Your API Credentials

Log into your merchant dashboard

Navigate to Settings > API Keys

Click "Generate New Keys"

Securely store your API Key (pk_live_) and API Secret (sk_live_)

Important: Your API Secret is shown only once. Store it securely and never expose it in client-side code.

Step 2: Create a Payment

To create a payment, send a POST request to our API:

curl -X POST https://api.pulse2pay.com/api/merchant/v1/payments \
  -H "Content-Type: application/json" \
  -H "X-Pulse2Pay-Key: pk_live_your_api_key" \
  -H "X-Pulse2Pay-Signature: your_hmac_signature" \
  -H "X-Pulse2Pay-Timestamp: 1705320000000" \
  -d '{
    "amount": "100.00",
    "currency": "USDT",
    "network": "TRON",
    "tokenStandard": "TRC20",
    "metadata": {
      "customer_email": "[email protected]"
    }
  }'

The response includes a unique TRON address for the customer to send USDT:

{
  "paymentId": "a1b2c3d4-e5f6-7890-abcd-ef1234567890",
  "status": "pending",
  "amount": "100.00",
  "currency": "USDT",
  "network": "TRON",
  "generatedAddress": "TXyz...abc123",
  "expiresAt": "2025-01-15T12:30:00.000Z"
}

Step 3: Display Payment Instructions

Show the customer:

The USDT amount to send

The TRON address (with QR code)

The payment deadline (30 minutes)

Step 4: Handle Webhooks

When the payment is confirmed, we'll send a webhook to your endpoint:

{
  "id": "evt_a1b2c3d4_1705078500000",
  "type": "payment.confirmed",
  "createdAt": "2025-01-15T12:05:00.000Z",
  "data": {
    "paymentId": "a1b2c3d4-e5f6-7890-abcd-ef1234567890",
    "status": "confirmed",
    "amount": "100.00",
    "currency": "USDT",
    "network": "TRON",
    "netAmount": "99.00",
    "feeAmount": "1.00",
    "txHash": "abc123...",
    "generatedAddress": "TXyz...abc123",
    "confirmations": 19
  }
}

Always verify the webhook signature before processing. See our webhook security guide for details.

Step 5: Verify Payment Status

You can also poll the payment status:

curl https://api.pulse2pay.com/api/merchant/v1/payments/a1b2c3d4-e5f6-7890-abcd-ef1234567890 \
  -H "X-Pulse2Pay-Key: pk_live_your_api_key" \
  -H "X-Pulse2Pay-Signature: your_hmac_signature" \
  -H "X-Pulse2Pay-Timestamp: 1705320000000"

Best Practices

Always verify webhooks: Use HMAC signatures to prevent spoofed notifications

Handle edge cases: Payments can expire, fail, or be underpaid/overpaid

Show clear instructions: Display the exact amount and address prominently

Set idempotency keys: Use idempotencyKey to prevent duplicate payments
