We need to check the playstore services are available or not before implementing push notification?

Hello,
In standard GCM we check for playstore services availablity, if not we will prompt messagebox, does we have to make the samething here or does backendless handles automatically?

I am not exactly sure what you’re asking about. If you’re asking whether Backendless would check whether GCM messaging API is enabled, the answer is no, we do not check that.
