2. **Client ID** - OAuth client identifier
3. **Client Secret** - OAuth client secret
4. **Access Token** - (after OAuth flow)
5. **Refresh Token** - (after OAuth flow)

### Getting Credentials

#### Lightspeed Retail (R-Series)
1. Visit [Lightspeed Developer Portal](https://cloud.lightspeedapp.com/developers)
2. Create a new API application
3. Note your Client ID and Client Secret

#### Lightspeed Restaurant (K-Series)
1. Contact your Lightspeed Account Manager
2. Request API credentials
3. Choose trial or production environment

### OAuth Flow Example

```typescript
import { LightspeedClient } from '@busybee3333/lightspeed-mcp-server';

const client = new LightspeedClient({
  accountId: 'YOUR_ACCOUNT_ID',
  clientId: 'YOUR_CLIENT_ID',
  clientSecret: 'YOUR_CLIENT_SECRET',
  apiType: 'retail', // or 'restaurant'
  environment: 'production', // or 'trial'
});

// 1. Get authorization URL
const authUrl = await client.getAuthorizationUrl(
  'https://your-redirect-uri.com/callback',
  'employee:all', // scope
  'random-state-string'
);

// 2. User visits authUrl and authorizes
// 3. Exchange code for tokens
const tokens = await client.exchangeCodeForToken(
  authorizationCode,
  'https://your-redirect-uri.com/callback'
