To demonstrate the practical application of payment gateway integration, let's explore some code examples that illustrate how to integrate a payment gateway using Axra.

### JavaScript/Node.js Example

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

```javascript
const axios = require('axios');

async function processPayment() {
try {
const response = await axios.post('https://api.axra.com/payments', {
amount: 1000,
currency: 'USD',
paymentMethod: {
type: 'card',
card: {
number: '4111111111111111',
exp_month: 12,
exp_year: 2023,
cvc: '123'
}
}
}, {
headers: {
'Authorization': `Bearer YOUR_API_KEY`
}
});
console.log('Payment successful:', response.data);
} catch (error) {
console.error('Error processing payment:', error.response.data);
}
}

processPayment();
```

### cURL Example

For testing purposes, you can use cURL to simulate a payment request:

```bash
curl -X POST https://api.axra.com/payments \
-H "Authorization: Bearer YOUR_API_KEY" \
-H "Content-Type: application/json" \
-d '{
"amount": 1000,
"currency": "USD",
"paymentMethod": {
"type": "card",
"card": {
"number": "4111111111111111",
"exp_month": 12,
"exp_year": 2023,
"cvc": "123"
}
}
}'
```

### HTML Frontend Example

Integrating a payment form on your website:

```html
<form id="payment-form">
<label for="card-number">Card Number</label>
<input type="text" id="card-number" name="card-number" required>

<label for="exp-month">Expiration Month</label>
<input type="text" id="exp-month" name="exp-month" required>

<label for="exp-year">Expiration Year</label>
<input type="text" id="exp-year" name="exp-year" required>

<label for="cvc">CVC</label>
<input type="text" id="cvc" name="cvc" required>

<button type="submit">Submit Payment</button>
</form>

<script>
document.getElementById('payment-form').addEventListener('submit', async (event) => {
event.preventDefault();
const cardNumber = document.getElementById('card-number').value;
const expMonth = document.getElementById('exp-month').value;
const expYear = document.getElementById('exp-year').value;
const cvc = document.getElementById('cvc').value;
// Process payment using Axra's API
});
</script>
```
