Question

我是paypal的新用户，我需要为我的客户实施订阅（定期付款）。我正在使用paypal沙箱进行实施。我遵循paypal坚持创建定期付款资料的方式。获得成功＆＃34;来自SetExpressCheckout，GetExpressCheckOut和DoExpressCheckOut的确认。我尝试使用DoExpressCheckOutpayment响应中的令牌创建循环付款配置文件，但来自CreateRecurrinpayment配置文件的响应返回失败，说明了ivnalid中的toke。我试着通过设置＆＃34; BILLINGAGREEMENTDESCRIPTION和BILLINGTYPE = RecurringPayments＆＃34;在我的设置快速结账请求上，但同样的错误仍然存在。

请找到我用于执行下面定期存款的代码。

SetEXpressCheckout

{
NameValueCollection values = new NameValueCollection();

            values["METHOD"] = "SetExpressCheckout";

            values["RETURNURL"] = PayPalSettings.ReturnUrl;

            values["CANCELURL"] = PayPalSettings.CancelUrl;

            values["PAYMENTACTION"] = "Sale";

            values["CURRENCYCODE"] = "USD";

            values["USER"] = PayPalSettings.Username;

            values["L_BILLINGTYPE0"] = "RecurringPayments";

            values["L_BILLINGAGREEMENTDESCRIPTION0"] = "Test subscription";





            values = Submit(values);



            string ack = values["ACK"].ToLower();



            if (ack == "success" || ack == "successwithwarning")

            {

                return new PayPalRedirect

                {

                    Token = values["TOKEN"],
                    Url = String.Format("https://{0}/cgi-bin/webscr?cmd=_express-checkout&token={1}",
                       PayPalSettings.CgiDomain, values["TOKEN"])
                 };
            }
             else

Answer 1

Sujth，正确的版本是51.0，满足您的需求。快乐的编码！

Answer 2

在您的SetExpressCheckout调用中，将VERSION设置为更新的内容，例如97.0。版本2.3中不存在L_BILLINGTYPE0和L_BILLINGAGREEMENTDESCRIPTION，因此API无法识别它们。
