What is Mobile Push Notification?
Mobile push notifications are the most popular
type of push notification and are often referred to simply as push
notifications or push, and it's important to follow push notification best
practices. They are mostly clickable pop-up messages that appear on mobile
screens.
Web push notifications are a way for web apps
to send notifications to a user's device even when the user is not currently on
the website. These notifications can be sent to a user's desktop or mobile
device and can be used to alert the user to new content or events on the
website or to re-engage the user with the website.
Oracle APEX with PUSH!
These push notifications are well-designed by
ORACLE to grab attention and can convey reminders, updates, and promotions. And
they appear very elegant
with industry-standard features that consist
of a message title, body, icon, and link by the user tapping on notifications,
then it gets redirected to an APEX app or a specific page of the app.
Apex sends a push notification to a user. All
devices that the user subscribed to will receive the push notification.
Enabling this option will:
Add
a new navigation bar entry: User Settings
Allow users to subscribe and unsubscribe to push notifications.
When
subscribed, users can receive push notifications from the APEX app.
This option is default enabled for any newer
applications.
Now , let's create a sample PUSH application.
Create a new application and choose the
Install Progressive Web App and Push Notification methods under the features
section.
Note: A couple of new pages #20000 and #20010
appears automatically for this feature.
These setting pages appear because of the Easy
Subscription method that lets users allow or disallow push notifications on
their device.
Easy Subscription
APEX users can subscribe to push notifications
from within their applications, while instance administrators can manage a
queue of notifications.
The setup of push notifications can be
configured either by Process or API invoke.
A new process type “Send Push Notification” is
introduced under the process configuration section and execution point of this
process invoke can be of any of its type like Before header , after region or
after submit .
This process type comes along with of the
supporting components of a process configurations setups like Server-side
Condition , Authorization Scheme ,Build

New fields to consider 👍
Under the setting tab:
To:
Username of the application user who should
receive the push notification. To receive the notification, the user must have
subscribed to the application first. Username is case-sensitive.
Title : Title of the push notification.
Body: Body of the push notification.
Next, the application must be installed first
before notification subscription by enabling the notification setting that
appears in the top right corner.
Initially, the notification appears as Off.
Push notifications need to be enabled by each
user. It works like that to respect user privacy and preferences. By explicitly
enabling push notifications, users grant the application permission to send
them notifications. This ensures that users have control over the information
they receive and can opt out if they feel overwhelmed or uninterested.
Enable push notifications by letting the
browser allow it as per the below example.
Subscription enabled.
Then, users log in and install the application
to let push notifications appear on their device.

We can also send the notifications using a new
apex_pwa API.
A sample script is given below
begin
apex_pwa.send_push_notification (
p_application_id => 112046,
p_user_name => 'DEMO',
p_title => 'My APEX
APP Notification',
p_body => 'Testing
the Push Notifications' );
end;
