try {
const response = await axios.post('https://api.axra.com/payments', {
amount: amount,
currency: currency,
source: source
}, {
headers: {
'Authorization': 'Bearer YOUR_API_KEY'
}
});
console.log('Payment processed:', response.data);
} catch (error) {
console.error('Error processing payment:', error);
}
}

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

### cURL API Testing Example

Use cURL to test Axra's payment API from the command line:

```bash
curl -X POST https://api.axra.com/payments \
-H "Authorization: Bearer YOUR_API_KEY" \

-d '{
"amount": 100,
"currency": "USD",
"source": "tok_sample"
}'
```

### HTML Frontend Integration Example

For frontend integration, embedding a simple payment form can be achieved as follows:

```html
<form id="payment-form">
<input type="text" id="card-element" placeholder="Card Number" required />
<button type="submit">Pay Now</button>
</form>

<script src="https://js.axra.com/v1/"></script>
<script>
const form = document.getElementById('payment-form');
form.addEventListener('submit', function(event) {
event.preventDefault();
Axra.createToken(form).then(function(result) {
if (result.error) {
console.error(result.error.message);
} else {
console.log('Token created:', result.token);
}
});
});
