Point client domain to my domain

Question

I have a website with subdomains for my clients (wildcard subdomain)

client1.test.com
client2.test.com

I want my clients to use their own domain If they want.

what kind of record needs to be added to point

client1.com => client1.test.com
shop.client1.com => client1.test.com

I´m using the free plan of cloudflare for www.test.com but I´m open to change it if it can´t be done

Answer 1

CNAME records would work for that. You could also use A records to point to the same IP as test.com

Answer 2

You need modify the cname to redirect your client1 IP on their domain provider to client1.test.com

You need modify the cname to redirect your client2 IP on their domain provider to client2.test.com

CNAME setup on cloud flare is for paid plans only
