A very basic question or two here:

- Did you set up the header of the request with the right api key token? From the included code it sort of looks like you are trying to use the old style API ley authentication in the URL.

- Have you looked at the necessary scopes for that API key that you will need for the desired action. The titke of the post says lists, but the code fragment looks like a contact related call.

Hope this is helpful
