Do server to server calls support grpc?

I want the unreal engine game server to send messages to nakama

First: Is it possible to use unreal engine nakama plugin for server to server calls on nakama?

My guess is no because I am guessing server to server calls are curl only.

But if it is possible what is the method? I tried using the following which circumvents client authentication but it failed

NakamaClient = UNakamaClient::CreateDefaultClient(Config.ServerKey, Config.Host, Config.Port, Config.bUseSSL, Config.bEnableDebug);
NakamaRealtimeClient = NakamaClient->SetupRealtimeClient();
OnReceivedMyTestRPC.AddDynamic(this, &UNakamaSubsystem::OnMyTestRPCSuccess);
OnReceivedMyTestRPCFail.AddDynamic(this, &UNakamaSubsystem::OnMyTestRPCFail);
NakamaRealtimeClient->RPC(TEXT("myTest_lua"), TEXT("server rpc payload"), OnReceivedMyTestRPC, OnReceivedMyTestRPCFail);

Second: Is it possible to use grpc for server to server calls in general? if so do I need to do anything special? or is it just researching and implementing grpc in lua?

Hello @alireza,

You should be able to make S2S calls using this function: nakama-unreal/Nakama/Source/NakamaUnreal/Public/NakamaClient.h at v2.10.0 · heroiclabs/nakama-unreal · GitHub.

Best.

Since that link goes to the master blob, if the code changes and the number of lines don’t match any longer then that link won’t point at the same method. Might be better to relink it to a tagged version. Or, at least mention the name of the function in case someone needs to go hunting.
