I'm using sign in with google in my game, which works wonderfully. However, I now want to make calls to google play services' REST api via cloud script. My flow would be something like this:
game client reports event -> cloudscript validates event vs title data -> cloudscript unlocks playfab achievement, and -> cloudscript reports achievement to google play game services
Is there a way to retrieve the token we got form login? If not, would the correct approach be to implement my own login via cloudscript so that I can store that server(playfab)-side?
