The Conversions API Gateway automatically identifies the websites (domains) on which the connected pixels fire, and provides a mechanism to block the pixel from sending the events to the Gateway when fired on selected websites.
Select Websites on the menu under Conversions API Gateway to access this feature. The Permitted Websites section lists all websites (domains) the Gateway has received events from, i.e. the pixels connected have fired on.
Click on See All to have the full list of Websites.
To avoid receiving events from a specific website (that is, tell the pixel not to send the event to the Gateway when firing on that website), set the domain to “Blocked” by clicking on Block. The website will be transferred to the Blocked Websites list, as shown below:
To add a custom domain to the Blocked Websites list click on the Add button and enter the domain to be blocked.
Click on Block; the entered domain will appear in the Blocked Websites list. When you set a domain to "blocked", events received by your Conversions API Gateway instance from that domain won't be published from your instance to Meta.
