# IP Allowlisting

> Gradial egress IP addresses to allowlist when your integration endpoints restrict API access by IP.

## Overview

Some integration endpoints — such as Braze, Marketo, Salesforce Marketing Cloud, or internal APIs — restrict inbound API traffic to known IP ranges. If your environment enforces IP-based access controls, you will need to allowlist the following Gradial egress IP addresses before connecting.

<Info>
  Not all integrations require IP allowlisting. This is only necessary if your endpoint actively blocks requests from unknown IPs. Most cloud-hosted instances do not require this step.

## Where to Configure Allowlisting

The exact location depends on your platform:

| Platform                       | Where to configure                                          |
| :----------------------------- | :---------------------------------------------------------- |
| **Braze**                      | Settings → Security Settings → API IP Allowlisting          |
| **Marketo**                    | Admin → Web Services (consult your Marketo admin)           |
| **Salesforce Marketing Cloud** | Setup → Security → Network Access                           |
| **Custom or internal APIs**    | Your network firewall, API gateway, or security group rules |
