Manage Meta pixel traffic permissions in Events Manager

The traffic permissions feature in Meta Events Manager enables you to create an "allow list" or a "block list" to control if domains are allowed to send events through your Meta pixel. Learn more about Meta pixel traffic permissions and reasons why you might see pixel events coming from unfamiliar website domains.

Once you've created an allow list or block list, you can switch to the other list type at any time. You can add or remove domains from a list at any time, but you can't recover events that were lost while a domain was blocked, and blocked events aren't included in your ads performance. Learn more about best practices for Meta pixel traffic permissions.

Before you begin

Create and install a Meta pixel on your website.
You need at least one of these pixel permissions to create or edit allow lists and block lists:

Repeat these steps for any other domains you want to add to your list.
Click Close.

After you've created your list, you can view and edit the domains in the Traffic permissions section of your pixel settings. Use the history table in Events Manager to see when a domain has been added to or removed from your pixel's allow list or block list. Learn more about your Meta pixel history.
