API Support for Custom Domain/Subdomain Management (Attach, Verify, Default Page & 404)

Currently, the only manual step left in our automated onboarding pipeline is connecting a client’s subdomain to a specific Website or Funnel inside HighLevel. While we can already automate DNS creation (CNAME/A records) and site/page provisioning via the public API, there is no API to programmatically add or verify a domain/subdomain, attach it to a Website/Funnel, set the default page and 404, or check SSL/connection status.
This feature would enable full automation for high-volume provisioning (dozens of domains monthly), reduce manual work, and ensure consistency. Ideally, the API would allow:
• Providing FQDN + Website/Funnel ID to initiate verification.
• Returning required DNS records and exposing connection/SSL status.
• Setting homepage/default path and a custom 404.
• (Optional) Supporting bulk operations for agencies managing multiple clients.
Having this functionality would unlock scalable onboarding and remove the last manual bottleneck.
