Push Notifications

App Center Push allows you to engage your users by sending them targeted push notifications.

How to set up Push Notifications

  1. Set up the platform specific push services: Firebase Cloud Messaging (FCM), Apple Notifications Service (APNs), Windows Notifications Services (WNS).
  2. Configure push settings in the App Center portal
  3. Integrate the Push App Center SDK

Follow specific instructions on how to set up Push Notifications in the App Center portal or in the following documentation

Sending Push Notifications

Send notifications to devices by clicking the Send Notification button in the upper-right corner of the page, a panel will appear prompting you to provide:

  • Campaign Name: The name used to track the campaign; this is internal to App Center, your users will not see it.
  • Title: The title of the notification sent to devices.
  • Message: The content of the push notification.

Send Notification

The next step is to select your target; you can send the notification to:

  • All registered devices: Send notifications to devices for all opted-in users.
  • Custom devices list: Send a notifications to the list of install IDs. You can get the install IDs by using our SDK API.
  • Audiences: Send notifications to a segment of your app's user population based on a set of device and custom properties.

Delay showing Push Notifications permission pop-up until the user clicks a button or a certain screen

You can call AppCenter.Start("{APP-SECRET}", services) without specifying the Push service. Then, once the user has opted in to receive push notifications, you can call AppCenter.Start(typeof(Push)) to start the Push service.

Note the application doesn't need to send the app secret in the second call to Start()

// call start with app secret WITHOUT Push
AppCenter.Start(appCenterAPIKey, typeof(Crashes), typeof(Analytics));

// then on button click do:

Custom Data in your notifications

Optional: send custom data as part of the push payload. The data is sent in a key-value format. This custom data can be intercepted in the app through Push SDK callback.

There are few reserved keywords in each platform that can be set via custom data:


  • color: The notification icon color, expressed in #rrggbb format. Only applies on devices running Android 5.0 and later.
  • icon: The notification's icon. Specify the name of the icon resource. Supports drawable and mipmap types. If this value isn't specified, default application icon is used.
  • sound: Add this key when you want the to play a sound. The value of this key is the name of a sound file in /res/raw/. This option only applies on devices running or targeting an Android version lower than 8. Sound is set by default on Android 8 and users can change notification settings for the group of notifications coming from AppCenter.


  • badge: Add this key when you want to modify the badge of your app icon. If this key is not included, the badge is not changed. To remove the badge, set the value of this key to 0.
  • sound: Add this key when you want the to play a sound. The value of this key is the name of a sound file in your app's main bundle or in the Library/Sounds folder of your app’s data container. If the sound file cannot be found, or if you specify default for the value, the system plays the default alert sound.
  • content-available: Add this key with a value of 1 to configure a silent notification. When this key is present, the system wakes up your app in the background and delivers the notification to its app delegate. For information about configuring and handling silent notifications, see Configuring a Silent Notification.
  • mutable-content: Add this key with a value of 1 to enable media attachments. The application needs to support a service extension to download and handle the attachment content. For more information you can refer to Apple documentations.


  • audio: Add this key when you want the to play a sound. this will modify the audio attribute for toast notifications.
  • image: Add this key when you want to modify the image attribute for tile and toast notifications.
