Want to use cloudflare and samcart to sell my videos

I activated cloudfare (to use samcart). but now there is the problem that I have already integrated my webflow account an cname record (www) (see screenshot). is there any other way to enable my subdomain (checkout.geistreich.academy)? How do subdomains work in cloudflare?

There’s no screenshot.

Subdomains work the same way domains do. They both use Cloudflare DNS, and you have the option to :orange: proxy them for additional Cloudflare services.
