## Understanding Payment API Documentation

Payment API documentation is the cornerstone of successful payment gateway integration. It provides developers with the necessary instructions and resources to incorporate payment functionalities into their applications.

### Key Components of Payment API Documentation

1. **Authentication:** Details on how to authenticate API requests, typically using API keys or OAuth tokens.
2. **Endpoints:** A list of available API endpoints with descriptions of their functions and expected responses.
3. **Code Examples:** Practical examples in various programming languages to demonstrate usage, often including JavaScript, cURL, and HTML.
4. **Error Handling:** Information on common errors and how to troubleshoot them.

### Example: Axra's API Documentation

Axra's API documentation is designed to be intuitive and comprehensive, offering developers clear guidelines for integration. Here’s a sample of how Axra’s API can be utilized:

#### JavaScript Example for Payment Processing
```javascript
const axios = require('axios');

async function processPayment() {
try {
const response = await axios.post('https://api.axra.com/payments', {
amount: 1000,
currency: 'USD',
source: 'tok_mastercard'
}, {
headers: {
'Authorization': 'Bearer YOUR_API_KEY'
}
});
console.log('Payment successful:', response.data);
} catch (error) {
console.error('Error processing payment:', error);
}
}

processPayment();
```

#### cURL Example for API Testing
```bash
curl -X POST https://api.axra.com/payments \
-H "Authorization: Bearer YOUR_API_KEY" \
-H "Content-Type: application/json" \
-d '{
"amount": 1000,
"currency": "USD",
"source": "tok_mastercard"
}'
```

#### HTML Example for Frontend Integration
```html
<form id="payment-form">
<input type="text" id="card-number" placeholder="Card Number" />
<input type="text" id="expiry-date" placeholder="MM/YY" />
<input type="text" id="cvc" placeholder="CVC" />
<button type="submit">Pay Now</button>
</form>
<script>
document.getElementById('payment-form').addEventListener('submit', function(event) {
event.preventDefault();
// Perform payment processing using Axra API
});
</script>
```
