Jak ustawić płatności setExpressCheckout

Mam możliwość utworzyć guziki ale chcę użyć SOAPa w php. Poniżej zamieszczam tajny kod i wyjaśnienie

$client = new SoapClient('https://www.paypal.com/wsdl/PayPalSvc.wsdl', array(
'soap_version' => '106.0',
'trace' => 1, 
'exceptions' => 1, 
'location'=> 'https://api-3t.paypal.com/2.0/',
));
		
$cred = array( 
'Username' => 'moj_prawidlowy username',
'Password' => 'KO23W9UJSB57HIJD',
'Signature' => 'AFcWxV21C7fd0v98TYYRCpSSRl31A7MbjiHUHOLDgv0HmrH.pJcvMr.r'
);
		
$Credentials = new stdClass();
$Credentials->Credentials = new SoapVar( $cred, SOAP_ENC_OBJECT, 'Credentials' );

$headers = new SoapVar( $Credentials,
 SOAP_ENC_OBJECT,
 'CustomSecurityHeaderType',
 'urn:ebay:apis:eBLBaseComponents'
);
						
$client->__setSoapHeaders( new SoapHeader( 
'urn:ebay:api:PayPalAPI',
'RequesterCredentials',
$headers ));
									
$args = array( 
'Version' => '106.0',
'ReturnAllCurrencies' => '1'
);
		
$GetBalanceRequest = new stdClass();
$GetBalanceRequest->GetBalanceRequest = new SoapVar( $args,
                                                    SOAP_ENC_OBJECT,
                                                    'GetBalanceRequestType',
                                                    'urn:ebay:api:PayPalAPI'
);

$params = new SoapVar( $GetBalanceRequest, SOAP_ENC_OBJECT, 'GetBalanceRequest' );
$result = $client->GetBalance( $params );

echo 'Balance is: ', $result->Balance->_, ' ', $result->Balance->currencyID;
/*
Powyzej kod dziala i wyświetla mi Balance. ale to kod z przykładu z PayPala
Teraz chciałem ustawić platności poniższym kodem
*/



//set Express checkout
		
											
$args2 = array(
'OrderTotal' => '10.0 PLN',

		);
		
$SetExpressCheckoutRequestDetails = new stdClass();
$SetExpressCheckoutRequestDetails->SetExpressCheckoutRequestDetails = new SoapVar( $args1,
                                                    SOAP_ENC_OBJECT,

//var_dump($SetExpressCheckoutRequestDetails);
//die();

var_dump($result);
die();

I mam błąd wersji ale to spowodowane jest chyba czymś innym bo nr wersji się zgadza 106. Ktoś ma jakś pomysł albo przykład jak to pocisnąć. To mój 4 dzień i chyba się poddaje :/
