Jason, I have created the API credential and works fine when in the cart have a product to puchase, but when insert in the cart a free product (digital product) get the error "2013-07-30T11:50:44ZFailuree76b4d2fb0b50Invalid DataThis transaction cannot be processed. The amount to be charged is zero.10525Error63.07066343" ["WA_HTTPS_Redirect"]=> int(0) }. This error is in debug mode, and modified the code in process_transaction.php:
if($WA_Store_Cart->GrandTotal() == 0) $WAGLOBAL_Test_Mode = true;
if ($WAGLOBAL_Test_Mode != true) {
?>
but the transaction with PPal is not by passed, if in the cart have a free product (zero cost). Have you a further suggestion??? Thank you
