PayPal沙盒返回内部服务错误

我试图使用PayPal沙箱测试自动信用卡处理，但遇到了一个问题。当我收取105美元的费用时，我得到一个调试id为de753957a889d的内部服务错误。例如，如果我返回并将金额更改为115美元，费用将按预期进行。我试过几种不同的金额，$105似乎是唯一一种给我错误的金额

以下是日志文件中的行：

您是否有可能在您的沙盒帐户上启用了“负面测试”？
/>应用程序>沙箱帐户>查找您的帐户>单击“配置文件>设置”

负面测试允许您通过将特定错误代码作为“AMT”值传递来触发特定错误代码，从而测试经典API的特定错误条件。
例如，对于API错误代码12345，您可以设置

AMT=123.45

---

对于您的错误场景，我看到我们在内部返回API错误代码10500。这让我强烈怀疑你已经为你的一个沙箱帐户开启了“负面测试”

如果您多次使用同一张卡的详细信息，您可能会收到此问题。

---

请使用其他卡，您将不会收到此类问题。

就是这样！非常感谢。这有文件记录吗？我想知道更多关于它是如何工作的。更具体地说，这个功能是否在任何地方都有文档记录。要知道将来我可能会测试哪些错误代码。我们的经典API（）有一些文档，但遗憾的是REST API的这个功能还没有完全实现。@PayPal_Robert FWIW我也有类似的问题，但（a）负面测试已经关闭；（b） 有时代码有效，有时无效。。。这让我想知道“沙箱”是否有自己的问题。阴性测试仅适用于业务a.k.a.服务商账户。
