How unreal dedicated server communicate with nakama server?

I use unreal dedicated server (ds), when the game is over, need ds and nakama communicate,through custom rpc or through websocket? If through websocket, add ds as a system player to the match, and realize it through Envelope_MatchDataSend?

Hello @hexun80149128, yes either approach would work, if you’re looking to use the RPC route have a look at Nakama: Introduction | Heroic Labs Documentation.
