Create a sending subdomain

client.EmailSending.Subdomains.New(ctx, params) (*SubdomainNewResponse, error)
POST/zones/{zone_id}/email/sending/subdomains

Creates a new sending subdomain or re-enables sending on an existing subdomain that had it disabled. If zone-level Email Sending has not been enabled yet, the zone flag is automatically set when the entitlement is present. A leftmost wildcard such as *.example.com is accepted only for accounts with wildcard Email Sending enabled. Wildcard senders share the base domain’s DKIM signing identity and cf-bounce.<base> return path.

Security

The previous authorization scheme for interacting with the Cloudflare API. When possible, use API tokens instead of Global API keys.
