Is there a way to check if a player is in game from UserId

Hey, so im making something for a dear friend of mine and I need to check if someone is in the game he owns. Im writing a script that is going to refund all to currency people who have bought currency within his game as there was an accidently data wipe. I already have a massive JSON file of all the purchases made with the amount of currency to give. To make sure data doesn’t get overwritten is there a way I can check if the player is in the game playing? If so im going to use messaging service…
