Sound in push notifications

When you send a notification, it can play an alert on your audience’s device. The sound file must be bundled in your app, and you’ll specify which sound you want to play in your notification payload.

When you send a push notification to iOS devices that uses our SDK, you can opt to send the Default system sound or no sound at all. If your audience’s phone is set to vibrate, or they’ve disabled sound permissions for your app, the Default setting will cause the device to vibrate rather than playing a sound.

In most cases, you should use the Default sound setting to make sure your audience hears (or feels) your message. But, before you send sound, you should understand:

  1. Your app needs permission from your users to play sounds. This is done by your app, not our SDKs. Here’s an example from our iOS sample app showing how to request sound permissions.
  2. iOS users can go into System Settings and disable sound permissions for your app. Enabling the Default setting doesn’t guarantee that your audience hears a sound when your message is delivered!

 We don’t support custom sounds yet

If you want to send a custom sound, you’ll need to handle it on your own, outside the SDK and use a custom payload when you set up your push notifications.
