## Code Examples for Payment API Integration

To illustrate how to integrate a payment API, let's consider a few practical code examples.

### JavaScript/Node.js Example

Here's how you can use Node.js to integrate a payment API:

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

async function processPayment(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);
}
}

const paymentData = {
amount: 1000,
currency: 'USD',
source: 'tok_visa'
};

processPayment(paymentData);
```

### cURL Example for API Testing

Testing API endpoints can be efficiently done using cURL:

```bash
curl -X POST https://api.axra.com/v1/payments \
-H "Authorization: Bearer YOUR_API_KEY" \
-H "Content-Type: application/json" \
-d '{
"amount": 1000,
"currency": "USD",
"source": "tok_visa"
}'
```

### HTML Example for Frontend Integration

To create a checkout form that integrates with your payment API:

```html
<form id="payment-form">
<input type="text" id="card-number" placeholder="Card Number" required>
<input type="text" id="expiry-date" placeholder="MM/YY" required>
<input type="text" id="cvc" placeholder="CVC" required>
<button type="submit">Pay Now</button>
</form>

<script>
document.getElementById('payment-form').addEventListener('submit', async function(event) {
event.preventDefault();
// Collect card details and send to payment API
});
</script>
```
