## What is Payment Processing?

Payment processing is the mechanism through which transactions are completed between buyers and sellers. It involves transferring funds from a customer's bank account to a merchant's account, and it typically includes authorization, capture, and settlement stages.

### Why Payment Processing Matters

1. **Customer Experience:** Quick and secure payment processing enhances the buyer's experience, leading to increased customer satisfaction and loyalty.
2. **Financial Security:** Ensures that transactions are securely handled, reducing the risk of fraud.
3. **Operational Efficiency:** Streamlines operations, saving time and reducing errors in transaction handling.

### Payment Processing in Action

Consider an e-commerce platform where users purchase items online. The payment process involves:
- **Authorization:** Verifying the transaction details and availability of funds.
- **Capture:** Holding the funds for the transaction.
- **Settlement:** Transferring funds to the merchant's account.

Axra simplifies this process by providing a robust payment SDK that developers can easily integrate into their applications, ensuring smooth, secure transactions.

## Understanding Payment SDK Documentation

**Payment SDK documentation** is a critical resource for developers looking to integrate payment solutions. It provides detailed instructions, examples, and best practices for using an SDK effectively.

### Key Components of SDK Documentation

2. **API References:** Detailed descriptions of available classes, methods, and parameters.
3. **Code Examples:** Practical examples to demonstrate usage.
4. **Error Handling:** Information on common errors and troubleshooting tips.
5. **Security Guidelines:** Best practices for secure transaction processing.

amount: amount
});
console.log('Payment processed successfully:', response.data);
} catch (error) {
console.error('Error processing payment:', error);
}
}

processPayment('your_token_here', 100);
```

```

<input type="text" name="cardNumber" placeholder="Card Number">
<button type="submit">Pay Now</button>
</form>
<script>
document.getElementById('payment-form').addEventListener('submit', async (event) => {
