Make an API CALL with (make/integromat)

Hi

I’m trying to make a call to the trello api in integromat but I can’t do it.

in the url I put:
https://api.trello.com/1/boards/idboard/?key=APIKey&token=APIToken

i take the ‘idboard’ from my trello board: Trello
is that correct?

in Headers do I need to put something or fill another field as well?
