This flag specifies a particular HostID type to use during checkout.
When this flag is set, only the specified HostID will be used during checkout. You should ensure that the HostID specified is a HostID type that is used by the client.
By default, all HostID types are enabled; therefore, when using this option you must first set the option LMX_OPT_HOSTID_DISABLED using LMX_HOSTID_ALL HostID as the HostID type. This will disable all HostIDs so that only the HostID specified in LMX_OPT_HOSTID_ENABLED will be used.
Enum value of type LMX_HOSTID_TYPE.
None. By default, all HostID types are enabled.
