我是贝宝的新手，我需要为我的客户实现订阅（定期付款）。我正在使用贝宝沙箱来实现它。我遵循贝宝坚持创建定期付款资料的方式。从 SetExpressCheckout、GetExpressCheckOut 和 DoExpressCheckOut 获得“成功”确认。我尝试使用 DoExpressCheckOutpayment 响应中的令牌创建定期付款配置文件，但来自 CreateRecurrinpayment 配置文件的响应返回失败，说明 ivnalid 中的令牌。我尝试在我设置的快速结帐请求上设置“BILLINGAGREEMENTDESCRIPTION 和 BILLINGTYPE=RecurringPayments”，但同样的错误仍然存在。
请在下面找到我用来实现定期存款的代码。
设置EXpressCheckout
{
NameValueCollection values = new NameValueCollection();
values["METHOD"] = "SetExpressCheckout";
values["RETURNURL"] = PayPalSettings.ReturnUrl;
values["CANCELURL"] = PayPalSettings.CancelUrl;

values["CURRENCYCODE"] = "USD";
values["BUTTONSOURCE"] = "PP-ECWizard";
values["USER"] = PayPalSettings.Username;
values["PWD"] = PayPalSettings.Password;
values["SIGNATURE"] = PayPalSettings.Signature;
values["SUBJECT"] = "";
values["L_NAME0"] = "MyName";
values["L_AMT0"] = "20.00";
values["VERSION"] = "2.3";
values["AMT"] = PayPalSettings.OrderAmount;
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
{
throw new Exception(values["L_LONGMESSAGE0"]);
}
}
提交

GetExpressCheckout

CreateRecurringPaymentsProfileResponseType pp_response=new CreateRecurringPaymentsProfileResponseType();

return pp_response;
