Paypal ManagePendingTransactionStatus 方法返回错误

Question

我正在尝试使用 ManagePendingTransactionStatus 方法通过 PayPal 的经典 API (SOAP) 取消待处理的交易，但响应始终是内部错误。我已经尝试更改Action、DetailLevel、Version，并且我使用了各种（现有的）TransactionIDs，但没有任何效果。

有人经历过类似的事情吗？有没有我遗漏的配置？

我在 Windows 7 x64 上的本地主机中使用我的 ASP.NET WebForms（框架版本 4.5）应用程序中的沙盒环境。以下是请求内容：

根据文档，ManagePendingTransactionStatus API 操作接受或拒绝由欺诈管理过滤器持有的待处理交易。如果它因任何其他原因而待处理，则该操作可能会产生错误。
