I'm creating an actions on google smart home app. I need to use a server that lets me make external (to Google) calls. I've already tried it with Firebase, but it's not possible unless you upgrade your account. What platform could I use to accomplish this task?
I have already searched for alternatives to Firebase, and came up with platforms such us parse, back4app or horizon, but I don't actually know if they are suitable for my purpose. Does anyone know which one could I use and how can I link it with my actions on google app?
