The module Frontier::Client can be used for communication via XML-RPC in Perl. You can download the module from

Here is an example of how to retrieve the key file for a given license in KA:

1. Load required modules.

use Frontier::Client;
use MIME::Base64;

2. Define variables. API login, API password, KA endpoint URL, and key number. The URL for the KA endpoint must start with https://.

$login = 'apilogin'; # username for API
$pass = 'apipassword'; # password for API
$url = ''; # server url
$key = 'PLSK.00052355'; # key to retrieve

3. Create new server Frontier::Client object.

$server = Frontier::Client->new( 'url' => $url, 'debug' => 1 );

4. Create named array for authInfo struct.

%authInfo = ( login => $login,
             password => $pass);

5. Send call with name of API method and all parameters. %authInfo is the named array (struct) and $key is the Keynumber to query as defined above. The response XML will be stored in $result.

$results = $server->call('partner10.retrieveKey', \%authInfo, $key);

6. Check result code. The resultCode will be an element in the returned XML response. Check if the call finished successfully or with error.

if($results->{resultCode} != 100){
die("\nError retrieving key: $key\n");

7. Retrieve data from XML. Extract the keynumber and the actual key file from the response XML. The key file is BASE64 encoded, it needs to be decoded.

$key_number = $results->{keyNumber};
$key_file = decode_base64($results->{key}->value()) . "\n";

8. Write the key file to the file system (or database, etc).

open(KEY, ">$");
print KEY $key_file;

You can then try installing the Key file to the product.

Note: Your LWP::UserAgent installation needs to support https connections to be able to connect to KA Partner API.
