在.NET中使用PayPal沙盒的'安全标题无效'

我在ASP.Net C＃4.0中使用PayPal沙箱。 我添加了以下Web引用：

https://www.sandbox.paypal.com/wsdl/PayPalSvc.wsdl
https://www.paypalobjects.com/wsdl/PayPalSvc.wsdl 

当我运行这段代码时：

PayPalAPIHelper.PayPalSandboxWS.SetExpressCheckoutReq req = new PayPalAPIHelper.PayPalSandboxWS.SetExpressCheckoutReq()
        {
            SetExpressCheckoutRequest = new PayPalAPIHelper.PayPalSandboxWS.SetExpressCheckoutRequestType()
            {
                Version = Version,
                SetExpressCheckoutRequestDetails = reqDetails
            }
        };

        // query PayPal and get token
        PayPalAPIHelper.PayPalSandboxWS.SetExpressCheckoutResponseType resp = BuildPayPalSandboxWebservice().SetExpressCheckout(req);

在我的resp对象中，错误消息说：

安全标头无效

我被告知给它正确的API凭证。 我注册了developer.paypal.com，我假设我使用的电子邮件地址和密码是我的有效凭证。 我如何以及在哪里给我的API凭证？ 谢谢

你在你的web.config文件中检查了端点地址吗？

这些应该被引用到以下url中

对于API证书=> SOAP https://api.sandbox.paypal.com/2.0/

对于API签名=> SOAP https://api-3t.sandbox.paypal.com/2.0/

如果您正在使用Signature，请使用以下代码

CustomSecurityHeaderType type = new CustomSecurityHeaderType();
            type.Credentials = new UserIdPasswordType()
            {
                Username = ConfigurationManager.AppSettings["PayPalUserName"], //Not paypal login username
                Password = ConfigurationManager.AppSettings["PayPalPassword"], //not login password
                Signature = ConfigurationManager.AppSettings["PayPalSignature"]
            };

请检查它为我工作的以下代码

CustomSecurityHeaderType type = new CustomSecurityHeaderType();
            type.Credentials = new UserIdPasswordType()
            {
                Username = ConfigurationManager.AppSettings["PayPalUserName"],
                Password = ConfigurationManager.AppSettings["PayPalPassword"],
                Signature = ConfigurationManager.AppSettings["PayPalSignature"]
            };
