Facebook Pixel - How to setup Facebook Pixel (Meta Pixel) domain allow list?

Articles on: OnePixel

You can control if domains are allowed to send events through your Meta Pixel using the Traffic Permissions feature in Meta Events Manager.
Traffic allow lists enable you to choose which domains you want to receive Pixel events from and excludes all others. Traffic block lists enable you to choose which domains you want to block Pixel events from and includes all others.

Reasons why you might see Pixel events coming from unfamiliar website domains include:

Someone else put your Pixel ID on their website. The Pixel is a piece of code that’s made up of the base code and your Pixel ID. When you add your Pixel to your website, your Pixel ID is public information. This means that other people can find your Pixel ID, add it to the Pixel base code and put it on their own website.

You set up your Meta Pixel using other application, third-party advertising technology or an iframe. This may cause redirects on your website. These redirects may appear as the referring URL and come from an unfamiliar website domain. In cases like these, we recommend allowing events from both domains so that you don’t inadvertently block events sent through your Pixel from Events Manager.

You set up difference domains for difference markets.

Setup Traffic Permissions for your Pixel:

Go to Events Manager.

Click the Data sources icon on the left side of the page.

Select your Pixel.

Click Settings.

Select Create Allow List or Create Block List from the dropdown menu under Traffic Permissions. Click on the button to confirm your selection.

Note: If you add a top level domain to a list, all subdomains are also included. For example, adding "" also adds "".

Repeat those steps for any other domains you want to add to your list.

Click Close.
