request.requestBody({
plan_id: 'P-12345678',
application_context: {
brand_name: 'Your Business',
shipping_preference: 'NO_SHIPPING'
}
});

try {
const response = await client.execute(request);
console.log(`Subscription ID: ${response.result.id}`);
} catch (error) {
console.error(error);
}
}

createSubscription();
```
