### JavaScript/Node.js Example for API Integration

Here's how you can integrate Axra's payment gateway API using Node.js:

```javascript

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

const paymentData = {
amount: 2000, // Amount in cents
currency: 'USD',
source: 'tok_visa', // Token obtained from front-end
description: 'Payment for Order #1234'
};

processPayment(paymentData);
```

### cURL Example for API Testing

Testing Axra's API with cURL is straightforward:

```bash
curl -X POST https://api.axra.com/v1/payments \
-H "Authorization: Bearer YOUR_API_KEY" \
-H "Content-Type: application/json" \
-d '{
"amount": 2000,
"currency": "USD",
"source": "tok_visa",
"description": "Payment for Order #1234"
}'
```

</form>

<script src="https://js.axra.com/v1/"></script>
<script>
var form = document.getElementById('payment-form');
form.addEventListener('submit', function(event) {
event.preventDefault();
// Implement token creation and submission
});
