Estes Freight Pickup Web Service Basic Authentication - php

Question

I am trying to create a test pickup request using Estes web services. This particular service requires Basic Authentication using my login credentials. However, I can't seem to figure out how to perform the authentication using PHP and SoapClient. I keep getting the following error:
PHP Fatal error: Uncaught SoapFault exception: [soapenv:Client] [ISS.0088.9164] Access to WSDescriptor estesrtpickup.base.ws.provider.soapws:pickupRequestSSL denied.
My last attempt I tried to pass the credentials into WSDL address, but to no avail. Like so:
$client_pickup = new SoapClient('https://USERNAME:PASSWORD#apitest.estes-express.com/tools/pickup/request/v1.0?wsdl');
Here is my current block of PHP code for the Pickup Webservice:
public static function estesFreightPickupRequest($option) {
self::$ShipToCity = preg_replace("/[^a-zA-Z0-9\s]/", "", $option->ShipToCity);
self::$ShipToStateProvinceCode = preg_replace("/[^a-zA-Z0-9\s]/", "", $option->ShipToStateProvinceCode);
self::$ShipToPostalCode = (string)$option->ShipToPostalCode;
self::$ShipToPostalCode = substr(trim(self::$ShipToPostalCode), 0, 5);
self::$ShipToPostalCode = str_pad(self::$ShipToPostalCode, 5, "0", STR_PAD_LEFT);
self::$ShipToAddressLine = preg_replace("/[^a-zA-Z0-9\s]/", "", $option->ShipToAddressLine);
$Weight = $option->weight;
$d = strtotime("tomorrow");
$request_date = date("Y-m-d", $d);
$path_to_wsdl_pickup = "https://apitest.estes-express.com/tools/pickup/request/v1.0?wsdl";
ini_set("soap.wsdl_cache_enabled", "0");
$client_pickup = new SoapClient('https://USERNAME:PASSWORD#apitest.estes-express.com/tools/pickup/request/v1.0?wsdl');
ini_set("soap.wsdl_cache_enabled", "0");
$header_pickup = new SoapHeader('http://www.estes-express.com/tools/pickup');
$client_pickup->__setSoapHeaders($header_pickup);
//Enter the body data for WSDL
$request_pickup = array(
'requestNumber' => date("Y-m-d"),
'shipper' => array(
'shipperName' => 'COMPANY NAME',
'accountCode' => 'ACCOUNT CODE',
'shipperAddress' => array(
'addressInfo' => array(
'addressLine1' => '1620 TEST CT',
'city' => 'SOMETOWN',
'stateProvince' => 'MO',
'postalCode' => '65222',
'countryAbbrev' => 'US'
)
)
),
'requestAction' => 'LL',
'pickupDate'=> date("Y-m-d"),
'pickupStartTime' => '1200',
'pickupEndTime' => '1500',
'totalPieces' => '1',
'totalWeight' => '100',
'totalHandlingUnits' => '1',
'whoRequested' => 'S'
);
try {
$response_pickup = $client_pickup->createPickupRequestWS($request_pickup);
//Error log the request and response
error_log($client->__getLastRequest());
error_log($client->__getLastResponse());
//$rateReply = $response->quoteInfo->quote->pricing->totalPrice;
//Get the response data
$result_array = array();
$result_array['totalPrice'] = $estes_total_rate_amount;
return $result_array;
} catch (SoapFault $exception) {
error_log('ERROR LOG::' . $exception, $client);
}
}
