1. Go to Settings > Domains.
  2. Click Verify domain.
  3. In the Verify Custom Domain window, copy the Canonical Name.
    Note:

    Some DNS providers do not support a trailing period in the CNAME. If you are using one of these DNS providers, omit the trailing period from the CNAME record.

  4. Add the Canonical Name to the CNAME record for your custom domain.
    Note:

    The canonical name will not have a DNS resolution until you complete the steps in Verifying the custom domain name and Adding an SSL certificate.
