Sending custom Push Notifications to the Moodle App

There are two ways to send custom Push Notifications to the Moodle app users:

1. By using Moodle’s Message API implementing a message provider
2. By directly using the Airnotifier (Moodle’s Push Notification server) APIs

Main differences are:

By using Moodle’s Message API, users (students, teachers, etc..) can opt-out to not receive custom notifications, they can also opt-in to receive them not only on the app but also via email. Messages sent using this API can arrive to non app users.

Using the Airnotifier API will force the user to receive the notification unless they change their app settings to not receive any notification. Messages sent using this API will only arrive to active app users.
