There are a couple ways on how to have a Roblox game server communicate with Discord.
First, you can use webhooks to post data from the game server via HttpService
to post data from the Roblox server to the Discord webhook. There’s a guide on the DevForum to help you get started on it.
Another way is to use a Discord bot via an HTTP server. Using HttpService, the game server sends a request with the data as headers, as @HmmBilly said.
I’d recommend using webhooks instead of a Discord bot, which is much easier to setup. You don’t have to setup an HTTP server so that you can send data to the bot.
