What should be specified in the conf file for ddclent?

I’m trying to get ddclient 3.8.3 on an Ubuntu Server 20.04 with the Cloudflare protocol to update my DNSs. I’ve tried to use my global token and made a custom one for editing zones. As login I’ve tried to use my email and my zone ID. For server, I’ve tried www. Cloudflare .com wish gives me error 403 and 1020. I’ve also tried api. Cloudflare .com and then the connection get timed out. So what should be specified for server, login, and password on the ddclient.conf file?
