### Why Payment Gateways Matter

Payment gateways are essential for any business that accepts online payments. They ensure:
- **Security**: Encrypts sensitive information to protect it from fraud.
- **Fast Processing**: Speeds up the transaction process, providing a better customer experience.
- **Versatility**: Supports multiple payment methods, including credit/debit cards, digital wallets, and more.

### Real-World Example: Axra Payment Gateway

## How Payment SDKs Enhance Payment Gateways

A **payment SDK** (Software Development Kit) is a set of tools that allows developers to embed payment processing capabilities into applications seamlessly. SDKs simplify the integration process, making it easier for businesses to incorporate payment gateways into their existing systems.

### Key Benefits of Using Payment SDKs

- **Ease of Integration**: Reduces development time with pre-built functionalities.
- **Customization**: Offers the flexibility to tailor payment processes to business needs.
- **Cross-Platform Support**: Ensures compatibility across different devices and operating systems.

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

processPayment({
amount: 1000,
currency: 'USD',
source: 'tok_visa',
description: 'Payment for order #12345'
});
```

#### cURL Example for API Testing

```bash
curl -X POST https://api.axra.com/payments \
-H "Authorization: Bearer your-api-key" \

"currency": "USD",
"source": "tok_visa",
"description": "Payment for order #12345"
}'
```

#### HTML Example for Frontend Integration

event.preventDefault();
// Integrate Axra Payment SDK for tokenization and submission
