try {
const response = await axios.post('https://api.axra.com/payments', {
amount: req.body.amount,
currency: 'USD',
paymentMethod: req.body.paymentMethod
});
res.json(response.data);
} catch (error) {
res.status(500).send('Payment processing error');
}
});

app.listen(3000, () => console.log('Server running on port 3000'));
```

#### cURL Example for API Testing
