Preciso que o código abaixo (Requisição de Pagamento) seja adaptado ao intermediador de pagamentos PayU Recorrente (http://developers.payulatam.com/pt/api/), e que seja possível processar recorrencias enviando um formulario em post:

<?php
// Create the SoapClient instance
$url = "http://www.processamentofacil.com.br";
$client = new SoapClient($url, array("trace" => 1, "exception" => 0));

$servico = retornaServico($_REQUEST['servico']);

// Call wsdl function
$result = $client->__soapCall("creditCardDirectSale", [
"clientCode" => "30122",
"clientSerial" => "53619f87e5c141fa45541e1e7269cdce",
"referenceNum" => 'S' . time(),
"number" => $_REQUEST['num_cartao'],
"expYear" => '20' . $_REQUEST['ano_cartao'],
"expMonth" => $_REQUEST['mes_cartao'],
"cvvNumber" => $_REQUEST['cvv_cartao'],
"nameCreditCard" => $_REQUEST['nome'],
"flagCreditCard" => $_REQUEST['metodo'],
"dayMaturity" => date('d'),
"name" => $_REQUEST['nome'],
"firstName" => "",

"dateBirth" => "",
"genre" => "",
"docNumber" => $_REQUEST['pedido'],
"products" => "",
"services" => array(
array(
"serviceCode" => "3",
"serviceName" => "Suporte R$ 19.81",
"serviceDescription" => "",

)
),
"quota" => "0",
"amount" => "19.81",
"quotaAmount" => "19.81",

"discountValue" => "",
"userCode" => "399",

]);

list($codigoPortador, $codigoContrato, $codigoRetornoRede, $mensagemRetornoRede) = explode(',', $result);
?>
