Using the W3C Web Push API is it possible to send a push notification in batch so it is received by multiple users ? When subscribing a user agent for notification we obtain a unique endpoint such as:
endpoint":"https://fcm.googleapis.com/fcm/send/eAViP691.......
So if I want to send the same push to 1000 users, does it mean I need to make 1000 HTTP post requests to the push service ?
