Introduction to the Push Notifications Service


The Push Notifications service allows you to send native push notifications to different mobile operating systems.

  • Code once and push notifications to iOS and Android

  • Push notifications to defined groups

  • Push notifications to either iOS only or Android only

  • Push notifications to different variants of a mobile app

  • Push notifications from different back-end apps to the same mobile app

Currently the service supports:

Push Notifications Terminology

This section describes terminology that is associated with Push Notifications.

Push Application

A logical construct that represents an Mobile App, for example, Mobile HR.

Push Notification Message

A simple message to be sent to a Push Application.

Sender Endpoint API

A RESTful API that receives Push Notification Message requests for a PushApplication or some of its different Variants. The Server translates this request into the platform specific details and delivers the payload to the 3rd party cloud provides, which eventually might deliver the message to the physical device.


A variant of the Push Application, representing a specific mobile platform, like iOS or Android, or even more fine-grained differentiation like iPad or iPhone. There can be multiple variants for a single Push Application (for example, Mobile HR Android, Mobile HR iPad, Mobile HR iOS free or _Mobile HR iOS premium). Each supported variant type contains some platform specific properties, such as a Google API key (Android) or passphrase and certificate (Apple).

Administrative User Interface

(AUI) The Unified Push Admin UI Web UI that allows you manage Push Applications and Variants, view statistics and send Push Notifications to devices.

Privacy note

As explained in the How the UnifiedPush Server works section, the payload of the push notification is delivered to 3rd party Push Network providers, like Google or Apple.

It is highly recommended to not send any sensitive personal or confidential information belonging to an individual (e.g. a social security number, financial account or transactional information, or any information where the individual may have a reasonable expectation of secure transmission) as part of any Push Notification!

For analytic purposes on our Dashboard we store the content of the alert key sent to the UnifiedPush Server. The content of the alert key belongs to the metadata, which is deleted after 30 days, using a nightly job within the UnifiedPush Server.

How the UnifiedPush Server Works

The Push Notifications service offers a unified Notification Service API to the above mentioned Push Network Services. It can be seen as a broker that distributes push messages to different 3rd party Push Networks.

When using the UnifiedPush Server, please keep in mind that Push notification is a signalling mechanism and that it is not suitable to be used as a data carrying system (e.g. use in a chat application).
