I’ve completed this project last year but now I just written a step-by-step guide on how to send mobile app notifications using Oracle APEX REST API with Firebase Cloud Messaging (FCM) — secured via Oracle Wallet.
This article covers everything from setting up Firebase, configuring Oracle Wallet for HTTPS communication, to building a PL/SQL procedure that sends push notifications directly to your mobile app.
Highlights include:
✅ Secure Oracle Wallet configuration for REST calls
✅ Real-time push notifications via FCM
✅ Sample PL/SQL code to trigger alerts from APEX
✅ Visual workflow diagrams & architecture explanation
Whether you’re building an enterprise dashboard, an approval system, or IoT alerts — this integration will help your APEX apps communicate with mobile users in real-time.
