I'm trying to call a function from this webservice:
http://www.zulutrade.com/WebServices/Performance.asmx?WSDL
I'm sending all the requested params but I'm getting this error: Value cannot be null. Parameter name: source I think it's a server issue, but maybe I need to change something in my code:
$client = new SoapClient('http://www.zulutrade.com/WebServices/Performance.asmx?WSDL',
array('location' => "http://www.zulutrade.com/WebServices/Performance.asmx",
'trace'=>1,
"cache_wsdl" => 0));
$params = array
(
'providerId' => 109206,
'fromDateStr' => "1985-12-19",
'toDateStr' => "2013-05-06",
'validTrades' => true,
'lotSize' => "Mini",
'start' => 0,
'length' => 20,
'sortBy' => "buy",
'sortAscending' => true
);
try
{
$result = $client->GetProviderTrades($params);
}
catch (SoapFault $fault)
{
print_r($fault);
}
Any ideas? thanks
