What is the correct way of getting an app key in google? - google-custom-search

Question

I'm trying out a simple code I found using www::google::customsearch. I know that google and yahoo has already change its policy in allowing these searches.
use strict;
use warnings;
use Data::Dumper;
use WWW::Google::CustomSearch;
my $api_key = 'Your_API_Key';
my $cx = 'Search_Engine_Identifier';
my $engine = WWW::Google::CustomSearch->new(api_key => $api_key, cx => $cx);
print Dumper($engine->search("Google"));
I am not sure if this module will work. I was just trying to test it. This is a sample from cpan. I tried running the code I keep getting a missing argument which is the api key.
This is so far what I have done. I have signed in google and created a custom search engine. I copied the search engine reference code. I have tried the example code in javascript. I placed it in a sample html. It works.
I have also signed in google and turned on custom search engine api, and generated an app key.

I tried running the code I keep getting a missing argument which is the api key.
You did not try to execute the given code as it is, did you? You are supposed to pass the actual key in below line.
my $api_key = 'Your_API_Key';
Your_API_Key should be replaced with the key you get from Google API console.

Quoting from the documentation on how to find it.
The JSON / Atom Custom Search API requires the use of an API key,
which you can get from the Google APIs console. The API provides 100
search queries per day for free. If you need more, you may sign up for
billing in the console.
The official Google API document can be found here. For more
