# Whitelist domains

Whitelist all the domains that your requests will originate from.

## Overview

For requests to go through properly, your domains need to be whitelisted first. If they're not, any requests originating from them will be blocked.

Domain whitelisting is configured at the site level, rather than the merchant group or merchant level.

## Whitelist domains for existing sites

1. In the Unity Portal, go to **Merchant setup > Sites**.
2. Select a site from the list.
3. Go to the **General information** tab.
4. Scroll down to the *Whitelisted domains* section.
5. Click the **+ Add whitelisted domain** button. A new input field is displayed.
6. Enter your domain. You should only use valid domain formats. For example, `example.com`
rather than `http://example.com` or `www.example.com` (unless prefixes are required).
7. Once you leave the field, the domain will be validated.
8. If valid, scroll back to the top of the page and click the **Save** button in the top right.


Your domain is now whitelisted. You can repeat these steps for any additional domains.

## Whitelist domains during new site creation

1. In the Unity Portal, go to **Merchant Setup > Merchants**.
2. Select the relevant merchant.
3. Go to the **Sites** tab.
4. Click the **+ New site** button.
5. In the modal, fill in the required site details.
6. Scroll to the *Whitelisted domains* section.
7. Click on the **+ Add whitelisted domain** button and input the domain. You can add several if you'd like.
8. Click the **Save** button to confirm.


Your domain is now whitelisted.
