## 📦 Installation

```bash
npm install backend-template
```

## 🔧 Quick Start

```javascript
const BackendTemplate = require('backend-template');

// Initialize with your credentials
const integration = new BackendTemplate(
  'appnestUserId',
  'productId',
  'userId',
  'clientId',
  'clientSecret',
  'https://your-redirect-uri.com/callback',
  'YourIntegrationName'
);

// Make authenticated API requests
async function getUser() {
  try {
    const user = await integration.getUser();
    console.log('User data:', user);
  } catch (error) {
    console.error('Error fetching user:', error);
  }
}
```

## 🔑 Authentication

The BackendTemplate handles the complete OAuth 2.0 flow:

```javascript
// Exchange authorization code for tokens
const authResponse = await integration.exchangeAuthCode('authorization_code');

// Tokens are automatically refreshed when expired
const data = await integration.makeRequest({
  method: 'GET',
  endPoint: '/v3/users',
});
```

## 💾 Storage Management

```javascript
// Store data
await integration.setStorageV2({
  key: 'userData',
  data: { name: 'John Doe', email: 'john@example.com' }
});

// Retrieve data
const userData = await integration.getStorageV2({ key: 'userData' });
```
