There are two ways to set up push notifications with Rocket.Chat:
Push Gateway
Self Configured
Select this option if you and your users intend to use the official Rocket.Chat mobile applications. We set up a push gateway holding our keys to enable push alerts to be received on our official mobile application by any server. Doing this safeguards the secret keys required to transmit notifications to you and your users via Apple(APN) and Google (FCM) systems.
You'll have to white-label your app if you don't want to use our push gateway.
The push notification workflow for Rocket.Chat is designed to be fast, reliable, and flexible, allowing users to stay informed and engaged with their chat messages and channels even when they're not actively using the app. The below describes the workflow of Rocket.Chat notifications from when a message is sent to when its notification is delivered.
Here are some potential causes to watch out for if you notice that notifications are not being delivered. The notification will not be sent if:
The room notifications are disabled.
The user ignores the sender.
@here, @all notifications are disabled, and the message is @here, @all.
The user is not active, or their status is set to Busy.
The user notification is not connected to Desktop or Mobile.
The user settings to always display mobile notifications is not ON.
The user room preference is set to Nothing, or use a default preference set to Nothing.
The room members count is bigger than the limit for disabling notifications.
Notifications are determined based on server settings, user preferences, and subscriptions. User status (online, away, offline)is no longer considered for email and mobile push notifications. Instead, these notifications go to a new queue following these rules:
When the user is online, the notification is scheduled to be sent in 120 seconds.
When the user is away, the notification is scheduled to be sent in 120 seconds minus the amount of time he is away.
When the user is offline, the notification is sent immediately.
When the user reads a channel, all the notifications for that user are removed (clears the queue).
When a notification is processed to be sent to a user, and there are other scheduled notifications:
All scheduled notifications for the user are now rescheduled to the current time.
The current notification goes back to the queue to be processed ordered by creation date.
