const axios = require('axios');

async function processPayment(amount, currency, paymentMethod) {
try {
const response = await axios.post('https://api.axra.com/v1/payments', {
amount: amount,
currency: currency,
paymentMethod: paymentMethod
}, {
headers: {
'Authorization': `Bearer YOUR_API_KEY`,
'Content-Type': 'application/json'
}
});
console.log('Payment successful:', response.data);
} catch (error) {
console.error('Payment failed:', error);
}
}

processPayment(100, 'USD', 'credit_card');
```

### cURL Example for API Testing

Testing your payment gateway integration can be done easily with cURL. Here's a sample command:

```bash
curl -X POST https://api.axra.com/v1/payments \
-H 'Authorization: Bearer YOUR_API_KEY' \
-H 'Content-Type: application/json' \
-d '{
"amount": 100,
"currency": "USD",
"paymentMethod": "credit_card"
}'
```

### HTML for Frontend Integration

Integrating a payment form on your website can be straightforward. Here's a basic HTML structure:

```html
<form id="paymentForm">
<label for="cardNumber">Card Number:</label>
<input type="text" id="cardNumber" name="cardNumber">
<label for="expiryDate">Expiry Date:</label>
<input type="text" id="expiryDate" name="expiryDate">
<label for="cvv">CVV:</label>
<input type="text" id="cvv" name="cvv">
<button type="submit">Pay Now</button>
</form>
<script src="https://sdk.axra.com/v1/axra.js"></script>
<script>
