## 🚀 Quick Start

### 1. Get Your Credentials

Contact Lexamica to receive:

* **Organization ID** — identifies your firm
* **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
```

### 3. Read the Foundational Docs

Before diving into examples, understand the building blocks:

1. [Organizations and Authentication](/1.-organizations-and-authentication.md) — How API keys work
2. [Mapping Engine](/2.-mapping-engine.md) — How to configure field transformations
3. [Inbound Webhooks](/3.-inbound-webhooks.md) or [Webhook Subscriptions](/4.-webhook-subscriptions.md) — Depending on your data flow

### 4. Follow an Integration Example

Pick the [Integration Examples](/example-integrations.md) that matches your use case and follow it step-by-step.

## 💡 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.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://integrate.lexamica.com/readme.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
