### Why the Best Payment Gateway Needs Excellent SDK Documentation

The best payment gateway is not only feature-rich but also provides intuitive and detailed SDK documentation. This documentation ensures that developers can integrate and customize solutions with minimal friction, maximizing efficiency and reliability.

## Choosing the Best Payment Gateway: Key Considerations

When selecting a payment gateway, consider factors such as transaction fees, ease of integration, security features, and support. However, robust SDK documentation should be a top priority as it directly affects the developer experience.

try {
const response = await axios.post('https://api.axra.com/payments', {
amount: 1000,
currency: 'USD',
source: 'tok_visa',
description: 'Sample Payment'
}, {
headers: {
'Authorization': `Bearer YOUR_API_KEY`

console.log('Payment processed:', response.data);

```bash
curl -X POST https://api.axra.com/payments \

```

```html
<form id="payment-form">

</form>

<script src="https://js.axra.com/v3"></script>
<script>
const form = document.getElementById('payment-form');
form.addEventListener('submit', async (event) => {
event.preventDefault();
const token = await axra.createToken({
number: '4242424242424242',
exp_month: '12',
exp_year: '2023',
cvc: '123'
});
