Since 12:35 UTC, hosting companies on cPanel/WHM can connect their servers the way Enhance panels already connect. Integrations → Connect cPanel/WHM gives you install commands for a server; pasted as root, they add a script that runs WHM's own read-only listaccts and get_domain_info every ten minutes and posts the result to us.
We chose push over a WHM API token on purpose: even a token limited to List Accounts can act as every cPanel user, so we do not ask for one. Each main domain, addon domain and real subdomain gets an HTTPS monitor, grouped by server; suspended accounts are paused, removed domains are paused and then removed after 24 hours, and resellers can give every cPanel user their own account. You see what was found, and the monthly cost, before anything is created. Details in cPanel/WHM integration.
