How do I make a bot for Discord that accepts players into a group based on UserId?

I know you perform API requests and this is technically botting, but I intend to make it easy for players to use our Discord verification service that we use via Dyno and get automatically accepted.

How do I even start? I have programming fundamentals down, I’ve just not branched far beyond C# and Lua in game-design applications. If I have to learn some javascript or python (I know python decently) then I don’t mind, just need to know what to do.
