- **Customer Experience**: They enable smooth, uninterrupted checkout experiences, reducing cart abandonment.
- **Multi-Currency Support**: Businesses can cater to a global audience with multiple currency transactions.
### Real-World Example: PayPal Integration
Consider a small business using PayPal as its payment gateway. By integrating PayPal, they can offer customers a trusted payment method, known for its security and ease of use, which can potentially increase conversion rates.

3. **API Integration**: Use Axra’s APIs to integrate payment functionalities into your application.
## Practical Code Examples
### Integrating with JavaScript/Node.js
Here's how you can use Node.js to integrate a payment gateway using Axra's API:
```javascript
const axios = require('axios');
async function processPayment(amount, currency) {
try {
const response = await axios.post('https://api.axra.com/payments', {
amount,
currency,
apiKey: 'your-api-key'
});
console.log('Payment processed:', response.data);
} catch (error) {
console.error('Payment error:', error);
}
}
processPayment(100, 'USD');
```
### Testing API with cURL
To test the payment processing API, use the following cURL command:
```bash
curl -X POST https://api.axra.com/payments \
-H "Content-Type: application/json" \
-d '{"amount": 100, "currency": "USD", "apiKey": "your-api-key"}'
```
