This feature will not function unless we have enabled it for your game. If you would like to have this feature enabled, please contact us
This function allows you to send a message to a player through a server-side POST, even if that player is offline. It can be used to let players know about updates, information directly relevant to their game status, or whatever else would make sense. However, please keep the messages relevant and well-targeted. We reserve the right to discontinue access to this API if a game is using it excessively or sending information that is not applicable to the recipient.
The targeted user must have played the game recently (within two weeks), and only one message can be sent per player per day.
username parameters are optional, but you must include one or the other.
