Click “Request a certificate”,

then select “Request a public certificate” and click “Next”.

Enter the wildcard domain name, e.g. *.domain.com

After clicking “Next”, go back to the list and click on the domain you just created to view its details.

Note down the CNAME name and value that need to be configured.

Configure the CNAME record in your domain’s DNS settings, then refresh the list a few times and wait for validation.

Once validated, the certificate is successfully issued.
