My goal is to able to switch from a sandbox user to production user. So, I have the code below. I am wondering if this is a good approach or if there is a better way. 
package Testme;

use warnings;
use strict;

use Exporter;

sub New {
    my ($class) = @_;
    my $self  = {
      sandbox => '0',

    };

    if ($self->{sandbox} == 1) {
        $self->{user}     = 'sandbox_user';
        $self->{password} = 'sandbox_password';
    }
    else {
        $self->{user}     = 'production_user';
        $self->{password} = 'production_password';
    }

    bless( $self, $class );
    return $self;
}
