Hi @Tamal Mondal ,

We can use this documentation for this: 

How to Use Push Notifications with OneSignal

hope it help you.

Hi Tamal,

According to the official documentation, you'll need to add your custom sound file to your project and configure the necessary settings.

I also found an old post suggesting a possible workaround.

Additionally, if you're working with Android, this Forge component might help you.

Thank you. But I want a proper solution where native custom Notification Sound will play. Also if app is not actively running.

Hi @Tamal Mondal 

Few pointers, hope this helps.

• Android reads custom sounds from path: /res/raw/ 
• You can upload your sound file at : resources/android/ 
• Outsystems maps resources/android/ to /res/raw/ in APK.
• The file must be lowercase with only .mp3, .wav, or .ogg and no spaces. 
• Also, for OneSignal payload, please do not include extension.

This should work even when the app is killed because Android plays the sound from its native folder.
