Facebook Notification
To send a Facebook notification, you will first need to set up your Facebook integration. It works the same way as on Telegram or Viber, with the additional feature of sending messages.
Default means there is no tag. You need to select the correct tag, and the user must be within the 24-hour window. If the user is outside the 24-hour window, the message will not be delivered — unless you use an approved Utility Message (see below).
Important: deprecation of Messenger Tags and Utility Messages
Meta has deprecated the old Messenger Tags as a way to get around the 24-hour window. Without a valid tag, there is no longer a compliant way to re-engage a user outside that window using the old method.
In place of tags, Meta introduced Utility Messages: pre-approved message templates that allow you to send follow-ups outside the 24-hour window, similar to Official WhatsApp Message Templates.
- Utility Messages cannot be used for marketing content — they are intended for updates related to an already existing interaction/transaction (e.g., order status, appointment reminder, confirmation).
- The "Manage and Access Page Utility Messaging" permission is required in the Facebook page integration.
- The message template must be submitted and approved before use, just as happens with WhatsApp templates.
If your flow depends on re-engaging users outside the 24-hour window on Facebook, check whether it still uses an old Messenger Tag and migrate to an approved Utility Message template.
