This document describes various best practices to consider when working with push notifications.

Iterable automatically tracks app uninstalls, as follows:
- You send a push campaign to a user.
- 12 hours later, Iterable sends a "ghost push" (not visible or audible) to that same user.
- If the app has been uninstalled and the ghost push cannot be delivered, Iterable tracks an uninstall.
Migrating GCM to FCM for Android
For Android push notification, Google Cloud Manager (GCM) has been deprecated in favor of FireBase Cloud Messages (FCM). If you are on GCM, you must migrate to the new system. You can migrate an existing GCM client app on Android to Firebase Cloud Messaging (FCM) using the instructions in this guide. Before getting started, keep in mind the following:
- GCM and FCM SDKs cannot co-exist within an application.
- GCM tokens retrieved via
InstanceID.getToken()will continue to work in FCM without any modification or renewal.
Please follow this Google documentation to complete the migration.
Renewing push certificates in Iterable
Your push notifications certificates are generally only valid for one year. Once they expire, you must renew them by creating new certificates and uploading them to Iterable.
- Apple should send you an email when your push notification certificate is close to expiring.
- It is worth adding a calendar reminder to ensure you know exactly when the certificates will expire.
- The Iterable dashboard will also note your certificates expiration date in the Mobile Apps section.
Please follow the steps in the previous section around creating certificates. Once you have new valid certificates, you can upload them to Iterable and continue to receive push in your app.
