Sets up and debugs remote push in Capacitor apps with @capacitor/push-notifications (FCM on Android, APNs on iOS), or Capgo alternatives @capgo/capacitor-firebase-messaging and @capgo/capacitor-notifications. Covers APNs keys, Push Notifications capability, AppDelegate `didRegisterForRemoteNotificationsWithDeviceToken` forwarding (stays in AppDelegate under the Capacitor 8.5 UIScene lifecycle), Android 13+ POST_NOTIFICATIONS permission, notification channels and icons…

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Push Notifications in Capacitor

## When to Use

TRIGGER when:
- Adding remote push (FCM / APNs) to a Capacitor app
- `registration` / `registrationError` never fire, or the token works on one platform only
- iOS token is a 64-hex APNs token but the backend expects an FCM token
- Notifications arrive in background but not in foreground (or vice versa)
- Android 13+ shows no prompt and nothing is delivered
- Upgrading to Capacitor 8.5 (UIScene) or 9 (`alert` presentation option removed)

Do not use:
- Opening the app from `https://` / `myapp://` links: `capacitor-deep-linking`
- Moving AppDelegate code to SceneDelegate: `capacitor-uiscene-migration`
- Device log capture: `ios-android-logs`
- Choosing other native plugins: `capacitor-plugins`

## Choose the plugin first (ask the user if unclear)

| Need | Plugin |
|------|--------|
| Official plugin; APNs token on iOS, FCM token on Android | `@capacitor/push-notifications` |
| FCM token on both platforms, topics, Firebase-first backend | `@capgo/capacitor-firebase-messaging` |
| Capgo-managed delivery (dashboard campaigns, badges, silent live-update checks, no own push server) | `@capgo/capacitor-notifications` |

How to install

The exact contents, by fingerprint

mdr add cap-go/capgo-skills/capacitor-push-notifications@sha256:3f9708f16854b0b6

The line at the top of this page pins the label git:20261011.86834d4, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
