ApiClient::delete()

[flanderboy]

Hello,
i have a problem about ApiClient::delete(). I try the documentations example but:

Call to undefined method MediaMath\TerminalOneAPI\ApiClient::delete()

my code is:

use MediaMath\TerminalOneAPI\Auth\AdamaCookieAuth;
use MediaMath\TerminalOneAPI\ApiClient;
use MediaMath\TerminalOneAPI\Transport\GuzzleTransporter;
use MediaMath\TerminalOneAPI\Management;
use MediaMath\TerminalOneAPI\Reporting;


$auth 		= new AdamaCookieAuth($token);
$transport 	= new GuzzleTransporter($auth);
$client 	= new ApiClient($transport);

$orgs 		= $client->delete(new Management\Advertiser([
				'id' => '...'
			]));

var_dump($orgs->data());
