One Signal Push Notifications Custom Sound

Is it possible to use custom sounds with onesignal. I’ve read that you must include the mp3 or sound file to the assets of the app and reference it? I tried briefly and it did not work. Same as the small notification icons on android.

Did anybody had success with it so far?

this might help you, and don’t forget to see the onesignal documentation which all the stuff you need and of course I am interested in onesignal too and working on it for a year. I like to add notification icons and I did get success with them by using js (REST API) I used the rest api but sounds… I don’t know as I didn’t test that as I don’t have a need of that… Try with REST API, that works and go to REST API REFERENCE
