I tried. See my post here: Push Notifications, OneSignal and Headaches
Long story short: the answer is no.
I could not get it to work in any useful manner. I reached out to OneSignal support directly and was initially told that Bubble integration “was on the roadmap”. I pointed out that their plugin was already live on the Bubble marketplace, but they were unable to provide any useful help.
I abandoned OneSignal in favor of Google’s Firebase Cloud Messaging.
I also used the Firebase Cloud Messaging plugin.
The whole thing was up and running in under 15 minutes. It does exactly what I needed for my particular use case, and it all worked as advertised.
