Choosing the best payment gateway is more than just a technical decision. It affects your transaction speed, security, and customer satisfaction. With the rise of fintech innovations, businesses need gateways that can offer flexibility, scalability, and robust security features.

## Payment API Examples: Bringing Theory into Practice

Payment APIs are the backbone of modern payment gateways, allowing developers to integrate payment processing capabilities into their applications. Here's how you can get started with payment API integration using real-world examples.

### Example 1: JavaScript for Payment API Integration
JavaScript is a popular language for client-side development. Here's how you can use it to integrate with a payment API:

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

async function createPayment() {
try {
const response = await axios.post('https://api.axra.com/payments', {
amount: 1000,
currency: 'USD',
source: 'card_1J2Y3K4L5M6N7O8P9Q',
description: 'Order #1234'
});
console.log('Payment Successful:', response.data);
} catch (error) {
console.error('Error creating payment:', error);
}
}

createPayment();
```

### Example 2: cURL for API Testing
cURL is a powerful tool for testing APIs from the command line. Here’s how to test a payment creation endpoint:

```bash
curl -X POST https://api.axra.com/payments \
-H 'Content-Type: application/json' \
-H 'Authorization: Bearer YOUR_API_KEY' \
-d '{
"amount": 1000,
"currency": "USD",
"source": "card_1J2Y3K4L5M6N7O8P9Q",
"description": "Order #1234"
}'
```

### Example 3: HTML for Frontend Integration
Integrating payment options directly into your frontend can enhance user experience. Here’s a basic example:

```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', function(event) {
event.preventDefault();
// Call your payment API here
});
</script>
```
