## Practical Payment API Examples

Let's explore some practical examples of how payment APIs can be integrated into your business infrastructure.

### JavaScript/Node.js Example
Integrating a payment API with JavaScript and Node.js can streamline your backend processes. Here's a basic example using Axra's API:

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

async function processPayment() {
try {
const response = await axios.post('https://api.axra.com/v1/payments', {
amount: 5000,
currency: 'USD',
paymentMethod: 'credit_card',
customer: {
id: 'cust_12345'
}
}, {
headers: {
'Authorization': 'Bearer YOUR_API_KEY'
}
});
console.log('Payment processed:', response.data);
} catch (error) {
console.error('Error processing payment:', error);
}
}

processPayment();
```

### cURL Example for API Testing
Testing your payment API integration with cURL is a straightforward way to ensure everything works as expected.

```bash
curl -X POST https://api.axra.com/v1/payments \
-H "Authorization: Bearer YOUR_API_KEY" \
-H "Content-Type: application/json" \
-d '{
"amount": 5000,
"currency": "USD",
"paymentMethod": "credit_card",
"customer": {
"id": "cust_12345"
}
}'
```

### HTML Example for Frontend Integration
Incorporating a payment form directly into your website can enhance the customer experience.

```html
<form id="paymentForm">
<input type="text" name="cardNumber" placeholder="Card Number" required />
<input type="text" name="expiryDate" placeholder="MM/YY" required />
<input type="text" name="cvv" placeholder="CVV" required />
<button type="submit">Pay Now</button>
</form>
<script>
document.getElementById('paymentForm').addEventListener('submit', async (event) => {
event.preventDefault();
const cardNumber = event.target.cardNumber.value;
const expiryDate = event.target.expiryDate.value;
const cvv = event.target.cvv.value;
// Integrate with Axra's payment API
});
</script>
```
