Друзья, нужно зделать обмен между 1с 8.2 и сайтом.
Вот схема которую дал разрабоччик 1c:

Запрос типа:
var_dump($client->__getFunctions());
Возвращает:

/*
        0 => string 'Import_orderResponse Import_order(Import_order $parameters)' (length=59)
        1 => string 'Export_productsResponse Export_products(Export_products $parameters)' (length=68)
        2 => string 'Import_orderResponse Import_order(Import_order $parameters)' (length=59)
        3 => string 'Export_productsResponse Export_products(Export_products $parameters)' (length=68)
 */

Вот мой код, дает ексцепшин:

public function test()
    {
        $client = new \SoapClient(
            $this->url,
            array(
                'login'         => $this->username,
                'password'      => $this->password,
                'soap_version'  => SOAP_1_2,
                'location'      => $this->url,
                'features' => SOAP_SINGLE_ELEMENT_ARRAYS,
                'trace' => 1
            )
        );

        try {
            $result = $client->Export_products();
            var_dump($result);
        } catch (\Exception $e) {
            print $e->getMessage() ."\n";

            print $client->__getLastRequest();

            print $client->__getLastResponse();
        }
    }
