Custom Get In NodeJS?

Question

So I'm making this API for http requests from roblox HttpService but I don't know how to properly get user-defined gets? kinda like luiboard.

OnxWebApp.get(`https://random_website.com${req}`, (req, res) => {
  Http.get(`https://random_website_lmao/users/${req.body}`, http_response => {
  
  })
})

I tried searching on nodejs documentation, youtube and other websites but couldn't get the solution
