In order to avoid dependence on third-party cookies and utilize first-party information, we'll create a subdomain to transmit all data securely via the subdomain.

​To create the subdomain, we'll generate a few records. You'll receive an automated email with instructions for your tech team to add these CNAME records in the domain manager, a process that takes only 1 or 2 minutes at max. Once completed, the Conversion API will be live.
