When should I use CNAME record instead of A records for domain verification?

This can be useful when DNS providers restrict adding duplicate records. A common situation is with domains hosted on Shopify.

Let's say your tagging server URL is sgtm.example.com. You should create A and AAAA DNS records to verify the domain on Stape. If Shopify manages your domain, creating both A and AAAA records for the same subdomain is impossible. Thus, you can't verify a custom domain on Stape.

To handle this issue, do not enable the checkbox Use A records instead of CNAME record.
