How do push notifications work in React Native?

Your backend sends a payload to Firebase Cloud Messaging (FCM) or Apple Push Notification service (APNs). FCM forwards to APNs for iOS devices. The OS receives the push, shows it to the user, and wakes your app when the user taps. Your React Native code handles the tap and deep links.

Do I need a paid Apple Developer account for push notifications?

Yes. Push notifications require an APNs key, which requires a paid Apple Developer Program membership ($99/year). There is no way around this for testing on real devices. The iOS Simulator does not fully support push testing.

What is the difference between Expo Push and Firebase Cloud Messaging?

Expo Push is a hosted service that wraps FCM and APNs for you, simpler but with a usage cap on the free tier. Firebase Cloud Messaging is free, unlimited, and works directly with the native SDKs. Use Expo Push for prototypes, FCM for production scale.

Why are my iOS push notifications not being delivered?

The most common causes: missing or expired APNs key in Firebase, permission not granted by the user, app signed with a development certificate but sending to production, or the device token belongs to a different app. Check Firebase Cloud Messaging delivery reports first.

Push Notifications in React Native — The 2026 Guide (Without the Docs Maze)

Push notifications are documented in 14 places across Expo, Firebase, and Apple. None of them tell you the actual flow. Here it is in one place.

Push notifications are documented in 14 places across Expo, Firebase, Apple, and React Native. None of them give you the whole picture. You bounce between docs for two days, get something working in dev, and then it breaks in production because you used a development cert.

This is the guide I wish I had on my first push integration.

The mental model first
