Need help with HTTP requests

local options = {
		Url = "https://classified-00000.firebaseio.com/users/-MAw7xPIxp3DEbfgnfE7.json", -- Host URL here
		Method = "PATCH",
		Body = HttpService:JSONEncode({
			["GROUP_ID"] = GroupId.Text,
			["SERVER_ID"] = ServerId.Text
		})
	}
	
	print(options.Body)
	
	local response = HttpService:RequestAsync(options)
	if response.Success then
		print("Status code:", response.StatusCode, response.StatusMessage)
		print("Response body:\n", response.Body)
	else
		print("The request failed:", response.StatusCode, response.StatusMessage)
	end
end)

So I’m trying to patch data to a certain table but I can’t get the value of -MAw7xPIxp3DEbfgnfE7.json automatically from getting the USER_ID and comparing it to the actual user_id of the person playing.
