# Authentication

The Auth Token authenticates all API requests to Leegality. This section explains how to generate the token from your dashboard.

When you enable the API, you receive two credentials:

1. **Auth Token**: Required in the `X-Auth-Token` header for all API requests
2. **Private Salt**: Used to verify webhook authenticity via HMAC-SHA1 signature. Learn more about [webhooks](https://knowledge.leegality.com/document-execution/api/webhooks/webhook-event-types)

1. Log in to your Leegality Dashboard
    - **Production:** https://dashboard.leegality.com
    - **Sandbox:** https://sandbox-dashboard.leegality.com
2. Click the **Settings** ⚙️ icon in the top right corner
3. Navigate to **Settings > API** from the left panel
4. Click the **Enable API** button to generate your credentials.
5. Click the **Copy** icon next to **Auth Token**

> **Info — Environment Separation**
>
> Sandbox and Production have separate *auth token* and *private salt*.

## Using Your Auth Token

Include `X-Auth-Token` and `Content-Type` headers in every API request:

```bash
curl --location 'https://app1.leegality.com/api/v3.0/sign/request' \
--header 'X-Auth-Token: your_auth_token_here' \
--header 'Content-Type: application/json' \
--data '{}'
```

> **Warning**
>
> Do not use an `Authorization: Bearer` header — Leegality uses `X-Auth-Token` exclusively. Including both will cause authentication to fail.
