Paypal 关于信用卡号码和类型的贝宝支付问题

面对问题

在沙盒中测试时，我添加了以下详细信息，但我遇到了此错误：

信用卡代码：

$cardDetails->CreditCardNumber = "4032039141982290";
$cardDetails->CreditCardType = "Visa";
$cardDetails->ExpMonth = "12";
$cardDetails->ExpYear = "2018";
$cardDetails->CVV2 = "123";
$cardDetails->CardOwner = "BILAL";

错误：

Payment - Failed
This transaction cannot be processed due to an invalid merchant configuration.
Error msg - This transaction cannot be processed. 
Please enter a valid credit card number and type.

请任何人告诉我问题是什么？

问题已解决。。。 由于我没有将帐户类型启用为“Pro”，所以出现了此问题。。 一旦您将业务帐户转换为“PRO”，错误将停止显示
