+# Description
+
+Requests NEX authentication data for game servers.
+
+The client SDK version must be at least 0x3010000, otherwise this returns error 0xC8A0C7F0.
+
+To request authentication data, the friends module sends a NASC `LOGIN` HTTP request using the given information (see [Online Play](Online_Play "wikilink") for more details).
+
+Once the completion handle has been signaled, the client can use [FRDU:GetGameAuthenticationData](FRDU:GetGameAuthenticationData "wikilink") to retrieve the data received from the server.
