A **payment gateway API** facilitates the interaction between your application and payment processing networks. It handles the complex transactions needed to process subscription payments securely and efficiently.

### Why Payment Gateway APIs Matter

1. **Seamless Integration:** They allow businesses to integrate payment solutions directly into their applications, providing a seamless customer experience.
2. **Security:** APIs ensure that all transactions are secure by adhering to industry standards like PCI DSS.
3. **Flexibility:** Customize your billing options and manage subscriptions easily.

### Axra: A Modern Payment Platform

## Implementing Subscription Billing with Payment Gateway APIs

### Example: Integrating Axra's Payment Gateway API

#### JavaScript/Node.js Example

Here's a basic example of integrating Axra's API using Node.js to create a subscription:

```javascript
const axios = require('axios');

async function createSubscription() {
try {
const response = await axios.post('https://api.axra.com/v1/subscriptions', {
customer_id: 'customer123',
plan_id: 'plan456'
}, {
headers: {
'Authorization': `Bearer YOUR_API_KEY`
}
});
console.log(response.data);
} catch (error) {
console.error(error);
}
}

createSubscription();
```

#### cURL Example

For testing the API using cURL:

```bash
curl -X POST https://api.axra.com/v1/subscriptions \
-H "Authorization: Bearer YOUR_API_KEY" \
-d "customer_id=customer123" \
-d "plan_id=plan456"
```

#### HTML Example

For front-end integration, you might include a payment form:

```html
<form action="/create-subscription" method="POST">
<label for="customer_id">Customer ID:</label>
<input type="text" id="customer_id" name="customer_id" required>
<label for="plan_id">Plan ID:</label>
<input type="text" id="plan_id" name="plan_id" required>
<button type="submit">Subscribe</button>
</form>
```

## Real-World Use Cases
