我正在尝试通过 C# 中的 PayPal 的 Adaptive Payments API 获得延迟的链式付款。我得到的错误没有任何意义，我在 .NET 上找不到任何东西来解决这个问题。
错误信息是： 无效请求：不能使用多个字段指定接收方
这是我发送的请求：
requestEnvelope.errorLanguage=en_US
&actionType=PAY_PRIMARY

&trackingId=51%7c0%7c6%2f16%2f2013+4%3a35%3a56+PM&
我指定了两个接收器，一个是 Primary，另一个不是。
我错过了什么？我已经尝试将 PAY 和 PAY_PRIMARY 作为操作类型。任何一个的结果相同。如果我只使用一个接收器，它可以工作。
这是代码：
WebClient webClient = new WebClient();

{

}
if (!String.IsNullOrEmpty(PRIMARY_RECEIVER_EMAIL_ADDRESS))
{

// All set. Fire the request
AdaptivePaymentsService service = new AdaptivePaymentsService();

如果您已经解决了这个问题或者可以发现错误，请告诉我！谢谢。
