* **Public Key** — for sending data to Lexamica
* **Private Key** — for configuration and management operations

### 2. Choose Your Integration Pattern

```
Are you SENDING cases to other firms?
│
├─► YES: You're an ORIGINATOR
│   └─► Start with: Lead Form Submission or Originator guides
│
└─► NO: You're a HANDLER (receiving cases)
    └─► Start with: Receive Cases or Handler Firm guides
```

## 💡 Webhooks vs. Polling

| Factor             | Webhooks                       | Polling                               |
| ------------------ | ------------------------------ | ------------------------------------- |
| **Latency**        | Real-time (seconds)            | Depends on poll frequency             |
| **Infrastructure** | Requires public HTTPS endpoint | Outbound requests only                |
| **Firewall**       | Needs inbound access           | Firewall-friendly                     |
| **Best for**       | Real-time sync                 | Batch processing, restricted networks |

Most integrations use **webhooks** for real-time updates. Use **polling** if your infrastructure doesn't support inbound connections.
