Roblox https problem

Hello my friend cannot use devforum currently so i am posting something for him, but he is asking this question:
How can I put launchData and Private Server code together in HTTPS URL
he said someone in the devforum did it but does not know how.

also yes he does have http on in security

What? If he means the LaunchData under GetJoinData, he can encode that into a json with the PrivateServerId and do what he wants with it.
