Delete domain
Delete a domain from the authenticated organization. Verified domains can be deleted at any time; their DNS records at the external DNS host are left untouched. Registered Bizzy-managed domains can only be deleted once their registration has expired and their DNS zone holds no records beyond the zone’s built-in ones (the apex NS set and SOA) — disable email for the domain first so Bizzy removes the email records it manages, and remove any remaining records yourself. A blocked deletion returns 409 with code REGISTERED_DOMAIN_NOT_EXPIRED, REGISTERED_DOMAIN_RENEWAL_IN_FLIGHT (a renewal is already queued or running for the domain), or REGISTERED_DOMAIN_DNS_NOT_EMPTY (which lists the blocking records in the error details). If the domain had email enabled, Bizzy also retires its email configuration — revoking the sending credential and removing the domain from the email provider. That cleanup is best-effort: if the provider is unreachable, the deletion still succeeds and any credential Bizzy could not revoke is recorded rather than lost track of.
