Is it possible to send a silent push notification so my app gets a data and then acts according to what it receives, but users are not aware of the message?
Countly has the ability to send “silent” push notifications to users. In order to do so, go to your dashboard, then Click on Messages > Messaging > Create message. When you select the type of message, make sure you click on “Data Only”. Any data you send to users will not be visible, but app will get this data and act according to your preferences.
