VAPID is the latest notification delivery mechanism that allows you to identify the sender server and deliver content to the end user without the involvement of GCM / FCM services.
Simply put, VAPID is a new notification sending mechanism that helps increase the number of deliveries and the speed of sending.
The update will also help improve overall operational efficiency, reporting accuracy, and event tracking.
Thanks to the new protocol, we will be able to support more browsers compared to GCM / FCM (for example, Microsoft Edge Browser), which means an increase in the subscriber base.
The update will take place in automatic mode and will not affect the system performance.
