Consider using Exporter

package MyConfig;

use Exporter 'import';
@EXPORT = qw();
@EXPORT_OK = qw(%amazon_config);
  
use strict;

our %amazon_config = (
    'name' => 'amazon',
    'host' => 'localhost',
    'user' => 'amazon',
    'pass' => 'somepass',
    'upload_path' => '/',
    'file_types' => [ qw( jpg mobi ) ],
);

1;

__END__
[download]

And your script:

#!/usr/bin/perl

use MyConfig qw(%amazon_config);

use strict;
use warnings;

print "Host: ",$amazon_config{host},"\n";
print "Name: ",$amazon_config{name},"\n";
[download]

Output

Host: localhost
Name: amazon
