## Implementing Payment Gateways with Payment SDK Documentation

To illustrate the importance of SDK documentation, let's consider integrating a payment gateway using Axra's SDK.

### JavaScript/Node.js API Integration Example
Below is a simple example of how to initiate a payment using Axra's Node.js SDK:

```javascript
const axra = require('axra-sdk');

axra.config({
apiKey: 'your-api-key',
environment: 'sandbox'
});

axra.payments.create({
amount: 1000,
currency: 'USD',
source: 'tok_visa',
description: 'Test Payment'
}).then(payment => {
console.log('Payment successful:', payment);
}).catch(err => {
console.error('Payment failed:', err);
});
```

### cURL API Testing Example
For quick testing purposes, here's a cURL command to create a payment:

```bash
curl -X POST https://api.axra.com/v1/payments \
-H "Authorization: Bearer your-api-key" \
-d "amount=1000" \
-d "currency=USD" \
-d "source=tok_visa" \
-d "description=Test Payment"
```

### HTML Frontend Integration Example
While SDKs often focus on backend integration, frontend elements are equally important. Here's how you might embed a payment form:

```html
<form id="payment-form">
<input type="text" name="card_number" placeholder="Card Number">
<input type="text" name="expiry_date" placeholder="MM/YY">
<input type="text" name="cvc" placeholder="CVC">
<button type="submit">Pay Now</button>
</form>

<script src="https://js.axra.com/v1/"></script>
<script>
document.getElementById('payment-form').addEventListener('submit', function(event) {
event.preventDefault();
// Collect payment information and send to Axra
});
</script>
```
