HOW IT WORKS
Android through FCM
Android clients obtain a device registration token. Your app can associate that token with a PUXIO user and receive pushes delivered through Firebase Cloud Messaging.
iOS through APNs
Native Apple notifications travel through APNs. An Apple app needs the appropriate entitlement, credentials and user authorization, with payload rules specific to Apple devices.
Treat tokens as changing credentials
Devices are not static. Tokens rotate, become invalid and must be updated or removed. A robust platform treats every invalid-token response as an operational event.
Deep links and foreground behavior
Notifications can open relevant screens. Display and interaction depend on platform permissions, OS restrictions and app state, not just the successful API response.
