.playerUniqueId
. It is highly recommended to have the unique ID as an identifier that would NEVER be changed. If this unique ID changes for a given player, you risk losing all original data for that player and hence losing their points and rewards on Gameball. Accordingly, it is NOT recommended to use email address or mobile number as the unique ID as both can be changed by the user at anytime.
