## How to Integrate a Payment Gateway with Your Shopping Cart

### Step-by-Step Integration Guide

1. **Select a Payment Gateway:** Choose a gateway that aligns with your business needs. Consider transaction fees, supported payment methods, and ease of integration.
2. **Obtain API Credentials:** Register with your chosen gateway to obtain API credentials (API Key, Secret Key).
3. **Install SDK or Libraries:** Use the SDK or libraries provided by the gateway to integrate with your shopping cart.
4. **Implement Payment Processing Code:** Use API calls to manage payment transactions.
5. **Test the Integration:** Conduct thorough testing using sandbox environments before going live.

### Code Examples

#### JavaScript/Node.js Example for API Integration

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

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

processPayment(100, 'USD');
```

#### cURL Example for API Testing

```bash
curl -X POST https://api.axra.com/v1/payments \
-H "Authorization: Bearer YOUR_API_KEY" \
-d "amount=100" \
-d "currency=USD"
```

#### HTML Example for Frontend Integration

<form action="https://api.axra.com/v1/checkout" method="POST">
