Question

我正在尝试创建一个使用PayPal Adaptive Payments API向用户付费的程序。我正在尝试实施支付用户的隐式支付方式（所以我不必批准每一个）。我目前正在使用字典为配置动态传递PayPal凭据，如下所示：

accountConfig = new Dictionary<string, string>();
accountConfig.Add("X-PAYPAL-SECURITY-USERID", "I HAVE PUT MY USERID HERE");
accountConfig.Add("X-PAYPAL-SECURITY-SIGNATURE", "MY SIGNATURE HERE"
accountConfig.Add("X-PAYPAL-SECURITY-PASSWORD", "MY PASSWORD HERE");
accountConfig.Add("X-PAYPAL-APPLICATIONID", "APP-80W284485P519543T");
accountConfig.Add("X-PAYPAL-REQUEST-DATA-FORMAT", "NV");
accountConfig.Add("X-PAYPAL-RESPONSE-DATA-FORMAT", "NV");

然后，我按如下方式配置付款：

AdaptivePaymentsService aps = new AdaptivePaymentsService(accountConfig);
Receiver receiver = new Receiver { email = "RECEIVER EMAIL", amount = payment.CommissionAmount };
List<Receiver> l = new List<Receiver> { receiver };
RequestEnvelope re = new RequestEnvelope { errorLanguage = "en_US" };
PayRequest payRequest = new PayRequest(
    re,
    "SERVICE",
    "http://cancelUrl",
    "USD",
    new ReceiverList(l),
    "http://returnUrl");
payRequest.senderEmail = "I HAVE PUT MY USERID HERE";
aps.Pay(payRequest);

根据文档，在隐式付款部分，您应该能够使用API来电者的帐户电子邮件作为发件人电子邮件，这被视为隐式付款。但是，我应该在哪里这样做？如果我这样做，将其添加到payRequest，我会收到MissingCredentialException，并显示以下错误消息：

Missing credentials for

没有其他信息。我做错了什么？

问题是我的身份证明不正确，基本上是由于我在网上找到的各种不同的例子。

此外，我发现THIS指南最终是最有帮助的（并为我工作）。我不确定为什么我没有及早发现这一点。希望它能帮助将来的某个人。
