Clay.io arrived just in time, as Playtomic going to be dead with tons of 503 errors in my apps, I get an official plugin with most of the same an some more features and great reliebility and a fantastic support.
@austin please work on the payments, cause this is the feature could reward your hard work! :)
I just found the Sandbox
in Clay.io docs. It's a great place before you make a plan for Clay.io features integration into your game.
