What is the issue you’re encountering

I want to serve an existing application living in another host through a subdomain on cloudflare.

What steps have you taken to resolve the issue?

Hey guys i have a question. I have an app hosted on Vercel. This website has subdomains: ocmi.peoplematic.io is one of them. Each subdomain is branded.

Now, i have my domain on cloudflare, is there a way to easily point a subdomain to my vercel app and to work smoothly? subdomains on vercel requires authentication to navigate, we are using cookies to store the token. How one would go to achieve something like this?

What feature, service or problem is this related to?

DNS records

Bets follow Vercel’s guide on adding custom domains:
