Who should create CAA records?

You should create CAA records in Cloudflare if each of the following is true:

• You uploaded your own custom origin server certificate (not provisioned by Cloudflare).
• That certificate was issued by a CA (not self-signed).
• Your domain is on a full setup (not a CNAME setup).
• When adding new Custom Hostname and your customer has existing CAA records. In this case, ask your customer to remove the existing CAA records or add the missing CAA record.
