Custom subdomain support with Cloudflare DNS and Netlify Pages

I have a saas app say abc.com serving from Netlify Pages and DNS is managed by Cloudflare.

I have set up this by adding CNAME/A in Cloudflare which points to abc.netlify.app/IP. Now I want my users to be able to set up their subdomain say new/anything.xyz.com to be able to point to abc.com

Notes

1. App is hosted with Netlify pages
2. DNS is managed by Cloudflare

Expected flow

1. User choose a subdomain from their dashboard (of our saas product), lets call it company1 and what he see is company1.abc.com
2. Now I want my customers to be able to use company1.abc.com as their redirect domain from their website say xyz.co, ab.xyz.co or anything.any.co. Expecting them to add company1.abc.com as a CNAME for their required domain.

Is this doable, then how? TA.

Solution 1:

As i know netlify need to define the custom domain first before you can add the CNAME record on DNS Zone.

So make sure the new.abc.com added to your custom domain list : https://docs.netlify.com/domains-https/custom-domains/
