# Adding content-available 1 to push notifications

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](https://developer.apple.com/documentation/usernotifications/pushing-background-updates-to-your-app).
