const response = await axios.post('https://sandbox.axra.com/api/v1/payments', {
amount: 1000,
currency: 'USD',
payment_method: 'credit_card',
card_details: {
number: '4242424242424242',
exp_month: 12,
exp_year: 2023,
cvc: '123'
}
}, {
headers: {
'Authorization': 'Bearer YOUR_API_KEY'
}
});
console.log('Payment created:', response.data);
} catch (error) {
console.error('Error creating payment:', error);
}
}

createPayment();
```

#### cURL Example for API Testing

```bash
curl -X POST https://sandbox.axra.com/api/v1/payments \
-H "Authorization: Bearer YOUR_API_KEY" \
-H "Content-Type: application/json" \
-d '{
"amount": 1000,
"currency": "USD",
"payment_method": "credit_card",
"card_details": {
"number": "4242424242424242",
"exp_month": 12,
"exp_year": 2023,
"cvc": "123"
}
}'
```

#### HTML Example for Frontend Integration

```html
<form id="payment-form">
<input type="text" id="card-number" placeholder="Card Number" required />
<input type="text" id="exp-month" placeholder="MM" required />
<input type="text" id="exp-year" placeholder="YY" required />
<input type="text" id="cvc" placeholder="CVC" required />
<button type="submit">Pay Now</button>
</form>

<script>
document.getElementById('payment-form').addEventListener('submit', async (event) => {
event.preventDefault();
// Implement payment processing using Axra's API
});
</script>
```
