I don't know much about delphi but i think you don't have to import the api's
just adding to the uses section the name windows which means windows library
then you just write down RegisterHotkey(param1,param2);
but then you have to controls the window's messages through the window procedure and i think delphi creates it's window automatically
so i guess the simplest way for you is run a loop and in it use GetAsyncKeyState(<VirtualKeyCode>)
in case GetAsyncKeyState return true the key is pressed

well if you wanna use HotKeys, i use them like this:

Code:
procedure Main;
begin
  @GChat:=pointer(GChattAddress);

  while(true) do
    begin

      if GetAsyncKeyState(vk_f1)<>0 then  // <--- GetAsyncKeyState //detects if  a key is pressed obiously it has to be in an                          // infinite loop ( while(true) do)
        begin
          MessageBox(0, 'This is an example of HotKey!', 'Sucess!', MB_OK or MB_ICONERROR) else
          sleep(150);
        end;

      sleep(30);
    end;
end;


if you're using a dll, when you inject it to your process and press F1, a mesagebox will pop up with " This is an example of HotKey! "
