const paypal = require('paypal-rest-sdk');

paypal.configure({
'mode': 'sandbox', // or 'live'
'client_id': 'YOUR_CLIENT_ID',
'client_secret': 'YOUR_CLIENT_SECRET'
});

const createSubscription = (planId, subscriber) => {
return new Promise((resolve, reject) => {
const subscription = {
'plan_id': planId,
'subscriber': subscriber,
'application_context': {
'brand_name': 'My Business',
'return_url': 'https://example.com/return',
'cancel_url': 'https://example.com/cancel'
}

if (error) {
reject(error);
} else {
resolve(agreement);
}
});
});
};
```

#### cURL Example for API Testing

For testing purposes, you can use cURL to create a subscription:

```bash
curl -v -X POST https://api.sandbox.paypal.com/v1/billing/subscriptions \
-H "Content-Type: application/json" \
-H "Authorization: Bearer YOUR_ACCESS_TOKEN" \
-d '{
"plan_id": "P-123456789",
"subscriber": {
"name": {
"given_name": "John",
"surname": "Doe"
},
"email_address": "customer@example.com"
},
"application_context": {
"return_url": "https://example.com/return",
"cancel_url": "https://example.com/cancel"
}
}'
```
