Mobile push delivery is planned
There is no mobile push delivery today. Nothing registers a device, no provider sends to one, and the notification channel vocabulary has no push member: an earlier push channel accepted declarations and sent nothing, so it was removed rather than left to look available.
For notifications available today, use the implemented in-app or email channels, or the transactional SMS service for its supported workflows.
Example — Choose an available notification path
A product needs to notify someone of a change now. It uses an implemented notification channel: a live in-app message for someone in the application, or an email for someone who is not.
For engineers
The notification channels are declared in notifications.shared.schemas.ts:
export enum CoreUserNotificationChannel {
EMAIL = 'email',
WEBSOCKET = 'websocket',
FRONT_END_SUCCESS = 'front_end_success',
}
A working push feature needs a device-subscription lifecycle, a sender/provider contract, payload templates and delivery handling. Those are implementation work, not configuration an application author can switch on.
Use in-app messages for an active application session, and the implemented notification channels appropriate to the product’s reach requirements. Transactional SMS is a separate service and does not imply general push support.
