Adding or removing a notification hub in AWS User Notifications
You can add or remove a notification hub using the AWS Management Console. When you add a new notification hub, User Notifications replicates new notifications into that Region. User Notifications doesn’t backfill earlier notifications. When you remove a notification hub, User Notifications stops replicating new notifications into that Region. User Notifications doesn’t remove previous notifications from that Region. However, notifications expire 90 days after they are generated.
To add or remove notification hubs
Open User Notifications in the AWS Management Console
. In the navigation pane, choose Notification hubs.
Choose Edit.
Either add Regions by selecting them or remove Regions by choosing the × next to a Region.
Choose Update.
