This feature can be configured for:

  • Customer App (Marketplace or Franchise App)

  • Business App

  • Driver App

Overview

Push notifications allow plataform to send real-time alerts directly to users’ devices, even when the app is not actively open.

These notifications are commonly used to:

  • Notify customers about order status updates

  • Send promotions and special offers

  • Inform users about new products or services

  • Improve customer engagement and retention

In our platform, push notifications are managed through OneSignal, which handles the communication between the system and the user's device.

Once configured, notifications can be automatically triggered by events such as:

  • Order received

  • Order accepted or rejected

  • Order ready

  • Order out for delivery

  • Order completed

How Push Notifications Work

  1. A user installs the mobile app.

  2. The user accepts push notification permissions.

  3. The device is registered with OneSignal.

  4. When an event occurs (for example, an order status update), the platform sends a notification request.

  5. OneSignal delivers the notification to the user’s device.

Benefits of Using Push Notifications

Push notifications help businesses:

✔ Provide real-time order updates
✔ Increase customer engagement
✔ Encourage repeat orders
✔ Send targeted promotions
✔ Improve the overall customer experience

Testing Push Notifications

After completing the configuration:
