## Payment API Examples

Let's delve into some practical payment API examples that demonstrate the power and flexibility of payment gateway APIs.

### Example 1: JavaScript Integration

Integrating a payment API using JavaScript can streamline the payment process within a web application. Here's a simple example using Axra's payment 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: 'card',
card: {
number: '4111111111111111',
expMonth: '12',
expYear: '2025',
cvc: '123'
}
});
console.log('Payment successful:', response.data);
} catch (error) {
console.error('Error processing payment:', error);
}
}

processPayment();
```

### Example 2: cURL for API Testing

cURL is a powerful tool for testing APIs. Below is an example of how you can use cURL to test Axra's payment gateway API:

```bash
curl -X POST https://api.axra.com/v1/payments \
-H "Content-Type: application/json" \
-d '{
"amount": 5000,
"currency": "USD",
"paymentMethod": "card",
"card": {
"number": "4111111111111111",
"expMonth": "12",
"expYear": "2025",
"cvc": "123"
}
}'
```

### Example 3: HTML Form for Frontend Integration

For frontend developers, integrating a payment form directly into a web page can enhance user experience. Here's a basic HTML example integrating Axra's payment API:

```html
<form id="payment-form" action="https://api.axra.com/v1/payments" method="post">
<input type="text" name="cardNumber" placeholder="Card Number" />
<input type="text" name="expMonth" placeholder="MM" />
