### Real-World Example
Consider a SaaS company offering a project management tool. By implementing recurring billing, the company ensures that every month, their users are automatically charged, allowing them to focus on enhancing their product rather than chasing payments.

## The Role of Payment Gateway API in Recurring Billing

### Why Payment Gateway API Matters
A **payment gateway API** is crucial in enabling seamless integration between your business’s billing system and payment processors. It automates the entire payment process, ensuring secure and efficient handling of transactions.

### Key Features of a Payment Gateway API
- **Secure Transactions**: Ensures data encryption and compliance with industry standards (e.g., PCI-DSS).
- **Scalability**: Supports growing transaction volumes without compromising performance.
- **Customization**: Allows businesses to tailor payment processes to their specific needs.

#### JavaScript Example for Axra API Integration
Here’s how you can use Axra’s API to set up a recurring billing cycle:

const createRecurringPayment = async () => {
try {
const response = await axios.post('https://api.axra.com/v1/recurring', {
customerId: 'cus_123456',
amount: 29.99,
currency: 'USD',
interval: 'monthly',
paymentMethod: 'pm_123456'
}, {
headers: {
'Authorization': 'Bearer YOUR_API_KEY'
}
});
console.log(response.data);
} catch (error) {
console.error('Error creating recurring payment:', error);
}
};

createRecurringPayment();
```

#### cURL Example for API Testing
Test the recurring billing setup with a simple cURL command:

```bash
curl -X POST https://api.axra.com/v1/recurring \
-H "Authorization: Bearer YOUR_API_KEY" \
-H "Content-Type: application/json" \
-d '{
"customerId": "cus_123456",
"amount": 29.99,
"currency": "USD",
"interval": "monthly",
"paymentMethod": "pm_123456"
}'
```
