Unassign an IP pool from a domain
Releases the domain back to the shared pool. The move is published to the mailing service after the local delete, is skipped entirely when the domain cannot be found, and a publish failure is logged and swallowed, so a 200 does not guarantee the mailing service has stopped using the dedicated addresses. Requires the domains:write scope.
Authorizations
An organization API key, prefixed bk_live_. Takes precedence over Authorization when both are sent. The key is bound to one organization, and the scopes it was issued with are enforced per endpoint.
Headers
Required when authenticating with an access token. Optional with an API key, whose own organization binding is authoritative; a value contradicting it is refused with 403.
