# IP Whitelisting

IP whitelisting ensures secure communication between your infrastructure and Leegality by restricting network access to specific IP addresses.

IP whitelisting works in two directions:

1. **Whitelisting Your IPs in Leegality**: Restrict which of your servers can make API calls to Leegality
2. **Whitelisting Leegality IPs in Your Infrastructure**: Allow Leegality to send webhooks and access your endpoints

## Whitelisting Your IPs in Leegality Dashboard

Configure which IP addresses from your infrastructure can access Leegality APIs.

#### Add Your Server IPs

1. Log in to your Leegality dashboard
2. Navigate to **Settings** > **API**
3. In **Whitelisted IPs** enter your server's public IP address
4. Click **+** to add the IP address.

Repeat for all servers that need API access.

> **Caution — Important**
>
> Once enabled, only API requests from whitelisted IPs will be accepted. Ensure all necessary server IPs are added before enabling.

#### IP Address Format

The Leegality dashboard accepts **valid IPv4 addresses only**.

**Format**: `xxx.xxx.xxx.xxx`

**Example**:
```
203.0.113.10
```

**To whitelist multiple servers**: Add each server's IP address separately by clicking the **+** button after each entry.

## Whitelisting Leegality IPs in Your Infrastructure

If your infrastructure has IP-based firewall rules, whitelist these Leegality IPs to receive webhooks and allow file uploads.

#### Production Environment IPs

Whitelist these IPs for production integrations:

```
15.207.242.28
3.6.114.195
3.7.137.254
```

#### Sandbox Environment IPs

Whitelist these IPs for sandbox/testing:

```
65.2.154.131
```

## IP Whitelisting Errors

| Code | Message | Description | Solution |
|------|---------|---------------------|----------|
| `173` | `IP verification failed.` | The IP address making the API request is not in the authorized whitelist configured for your API token. | Add your public IPs in Leegality Dashboard via [**Settings → API → Whitelisted IPs**](https://knowledge.leegality.com/document-execution/settings/account-level/API/how-to-whitelist-ip). 

Ensure all server IPs are whitelisted before enabling the feature — once active, only whitelisted IPs can make call to Leegality APIs. |
| — | `Please enter valid IPv4 address.` | The IP address entered in the dashboard is not a valid IPv4 format. | Use the format `xxx.xxx.xxx.xxx` (e.g. `203.0.113.10`). IPv6 addresses and incomplete values like `192.168.1` are not supported. |
