resourceRecord

Contains the CNAME record that you add to your DNS database for domain validation. For more information, see Use DNS to Validate Domain Ownership.

The CNAME information that you need does not include the name of your domain. If you include your domain name in the DNS database CNAME record, validation fails. For example, if the name is _a79865eb4cd1a6ab990a45779b4e0b96.yourdomain.com, only _a79865eb4cd1a6ab990a45779b4e0b96 must be used.
