## Practical Examples of Payment API Testing

To illustrate how payment API testing works, let's look at some practical examples using different programming languages.

### JavaScript/Node.js Example

Below is an example of a simple transaction using Axra's API with Node.js.

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

async function processPayment() {
try {
const response = await axios.post('https://api.axra.com/transactions', {
amount: 1000,
currency: 'USD',
payment_method: 'credit_card',
card: {
number: '4111111111111111',
exp_month: '12',
exp_year: '2025',
cvc: '123'
}
});
console.log('Transaction successful:', response.data);
} catch (error) {
console.error('Transaction failed:', error);
}
}

processPayment();
```

### cURL Example

For those who prefer command-line testing, here's how you can test the API using cURL:

```bash
curl -X POST https://api.axra.com/transactions \
-H "Content-Type: application/json" \
-d '{
"amount": 1000,
"currency": "USD",
"payment_method": "credit_card",
"card": {
"number": "4111111111111111",
"exp_month": "12",
"exp_year": "2025",
"cvc": "123"
}
}'
```

### HTML Frontend Integration

For frontend developers, integrating a payment form can be simplified with Axra's easy-to-use components.

```html
<form id="payment-form">
<input type="text" name="card_number" placeholder="Card Number" required />
<input type="text" name="exp_month" placeholder="Exp Month" required />
<input type="text" name="exp_year" placeholder="Exp Year" required />

</form>
<script src="https://js.axra.com/v1"></script>
<script>
document.getElementById('payment-form').addEventListener('submit', function(event) {
event.preventDefault();
// Add JavaScript code here to handle form submission and communicate with Axra API
});
</script>
```
