## Understanding Payment Gateways

### What is a Payment Gateway?

A **payment gateway** is a service that authorizes and processes online payments, bridging the gap between a customer's bank and the merchant's bank account. It plays a vital role in the payment processing ecosystem by ensuring that sensitive card information is encrypted and securely transmitted.

### Why Payment Gateways Matter in Freemium Billing

Freemium billing models, where basic services are offered for free while advanced features require payment, rely heavily on payment gateways to handle transactions smoothly. Without a robust payment gateway, converting users from free to paid tiers can become cumbersome, leading to potential revenue loss.

### Axra: A Modern Payment Gateway Solution

[Axra](https://www.axra.com) stands out as a modern, developer-friendly payment platform. With Axra, businesses can effortlessly integrate payment solutions into their applications. Axra provides a comprehensive API that supports various billing models, including freemium, while ensuring top-notch security and scalability.

## Code Examples for Payment Gateway Integration

Below are some practical examples of how to integrate a payment gateway using Axra's API.

### Node.js Example for Payment Processing

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

async function processPayment(amount, currency, source) {
try {
const response = await axios.post('https://api.axra.com/v1/payments', {
amount: amount,
currency: currency,
source: source
}, {
headers: {
'Authorization': 'Bearer YOUR_AXRA_API_KEY'
}
});
console.log('Payment successful:', response.data);
} catch (error) {
console.error('Payment failed:', error);
}
}

processPayment(1000, 'USD', 'card_1HkY0M2eZvKYlo2ClN9d2ZxL');
```

### cURL Example for API Testing

```bash
curl -X POST https://api.axra.com/v1/payments \
-H 'Authorization: Bearer YOUR_AXRA_API_KEY' \
-d 'amount=1000&currency=USD&source=card_1HkY0M2eZvKYlo2ClN9d2ZxL'
```

### HTML Example for Frontend Payment Form

```html
<form action="https://api.axra.com/v1/payments" method="POST">
<input type="hidden" name="amount" value="1000">
<input type="hidden" name="currency" value="USD">
<input type="text" name="card_number" placeholder="Card Number">
<input type="text" name="expiry_date" placeholder="Expiry Date">
<input type="text" name="cvc" placeholder="CVC">
<button type="submit">Pay Now</button>
</form>
```
