To send background (silent) updates using Insider's App Push, you can add content-available = 1 to your push notification payload.

iOS-only requirement

The content-available = 1 flag applies only to iOS (APNs). Android devices ignore this field.

App setup in Xcode

Before using background pushes, your app must enable Background Modes → Remote notifications in your app’s Xcode project. Without this, iOS will not deliver the background pushes.

Delivery behavior

  • Background pushes are not guaranteed.
  • iOS may delay, merge, or drop them depending on battery, device state, or push frequency.
  • Avoid relying on them for real-time guarantees.

For further information, refer to Apple's Pushing Background Updates to Your App.
