Question

So I previously was using ClientLogin for authorization in the Google AdWords API but after looking at AuthForInstalledApps it says that this mechanism has been deprecated in favor of OAuth2.0

I have registered my application in the API Consoles. Now I am trying to follow the perl example of how to set this up:

use_oauth2.pl

I cannot place the AdWords Client, credentials in ~/adwords.properties since I have multiple accounts that I will be doing Campaign Management operations on, and therefore multiple client ids.

But for now I tried to follow this example by using just one of my client’s info like this:

my $client = Google::Ads::AdWords::Client->new(
    {
        version  => 'v201206',
        developer_token => TOKEN,
        client_id => $google_account_id
    }
);

$client->get_auth_token_handler()->set_email($login);
$client->get_auth_token_handler()->set_password($password);

However when I step through this, when it tries to initialize the Client object it throws this error:

I am using Perl v5.8.8 . I have installed the latest Adwords Perl Client Library v2.7.2 . Is there some kind of dependency issue?
And how can I go about resolving this issue. Any information you can provide would be very helpful. Thanks.

It looks like I just needed to have the latest HTTP/Message.pm v6.0.3 module installed since the version I had installed did not have the method decode() which was being passed to the AUTOLOAD() subroutine in the HTTP/Message.pm module.
