# Notification Preferences and CXC Endpoint Removal

**New /v3/notificationPreferences Endpoint** – The `/v3/notificationPreferences` endpoint has been added to allow users to subscribe to individual notifications or notification groups in the Megaport Portal. This endpoint replaces the previous `/v2/notificationPreferences` endpoint. For more information, see [Email Notifications](/api-reference).

**Removed the PUT /v2/product/cxc/\{productUid} Endpoint** – The `PUT /v2/product/cxc` endpoint has been deprecated as all active CXC services have been migrated to VXCs. Users should access the `PUT /v2/product/vxc/{productUid}` endpoint instead.
