Subscriber list ID.

subscriber preferences. Pass
null to clear it.boolean
Private lists stay hidden from subscriber preferences unless you enable member
unsubscribe. Public lists can be discovered and joined there. Descriptions
always stay internal. Omission defaults to public on creation and preserves
visibility on update.
boolean
Allow existing members of a private list to see its name and unsubscribe in
email preferences. Defaults to
false on creation. On update, omit to
preserve the setting or pass false to disable it; null is rejected. The
setting is stored but has no effect on public lists. Members cannot join or
rejoin private lists through preferences.Responses
allowMemberUnsubscribe. Updates that set the same value can be safely retried; creating a list again creates another list, so inspect your lists after an uncertain creation response.
A non-boolean or null value for allowMemberUnsubscribe returns HTTP 422 without applying the change. Existing authentication and list-write permissions still apply.
