Update destination expiration time. The request must be sent regularly (e.g., daily, after logon) for the current user’s device. The request should be sent before or together with request that adds the destination to a rule or destination group. Destination expiration time is set to 2 months by default (configurable) after receiving the request. When the destination expires, the server deletes it from rules and destination groups:
•If the list of actions in a rule becomes empty, the server deletes the rule.
•If a destination group becomes empty, the server leaves it as is.
Thus, the server never deletes a rule that has a destination group (including empty group) or a destination that does not expire (e.g., email_notif or profile_sms_notif).
