Friends, you need to make an exchange between 1s 8.2 and the site.
Here is the diagram given by developer 1c:

Request type:
var_dump($client->__getFunctions());
Returns:

/*
        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)
 */

Here is my code, gives exceptions:

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();
        }
    }

It's decided.
You need to save the wsdl response, connect it in the constructor and specify the location without ?wsdl

$client = new \SoapClient
        (
            DOCROOT . "ex.wsdl" ,
            [
                'login'         => $this->username,
                'password'      => $this->password,
                'soap_version'  => '1.2',
                'cache_wsdl'    => WSDL_CACHE_NONE, 
                'features'      => SOAP_USE_XSI_ARRAY_TYPE,
                'location'      => $this->location,
                'exceptions'  => true,
                'trace'       => true
            ]
        );
