#### JavaScript Example for API Integration
```javascript
const axios = require('axios');

const processPayment = async (paymentData) => {
try {
const response = await axios.post('https://api.axra.com/payments', paymentData, {
headers: {
'Authorization': 'Bearer YOUR_ACCESS_TOKEN',
'Content-Type': 'application/json'
}
});
console.log('Payment successful:', response.data);
} catch (error) {
console.error('Payment failed:', error);
}
};

const paymentData = {
amount: 5000,
currency: 'USD',
paymentMethod: 'card',
cardDetails: {
number: '4242424242424242',
expMonth: '12',

};

processPayment(paymentData);
```

curl -X POST https://api.axra.com/payments \
-H "Authorization: Bearer YOUR_ACCESS_TOKEN" \
-H "Content-Type: application/json" \
-d '{
"amount": 5000,
"currency": "USD",
"paymentMethod": "card",
"cardDetails": {
"number": "4242424242424242",
