Hello Team,

I got Some Error When I create the Blank Order. Below is My Code.

$contactID=5536;  
$name=“Product”;  
$orderDate=date(“Y-m-d\TH:i:s”);  
$leadAffiliateID=0;  
$saleAffiliateID=0;  
$infusionsoft-\>invoices()-\>createBlankOrder($contactID, $name, $orderDate, $leadAffiliateID, $saleAffiliateID);

Error:

Hi @Sunny_Gajjar, I believe you’re seeing an issue with mismatched types for what the XML-RPC method is expecting. Try using a `DateTime` object; you can find an example [here](https://github.com/infusionsoft/infusionsoft-php#dates).
