有没有办法在PayPal Sandbox测试网站上测试Chargebacks / Disputes？
我尝试使用解决方案中心通过正常的争议费用方法和解决方案中心特定的沙箱“创建或解决案例”部分创建新案例。
无论哪种方式，我都可以将纠纷置于“通过PayPal审核”的状态。没有发送IPN通知。
此支持文章详细介绍了我希望在沙盒环境中模拟的预期步骤：https://ppmts.custhelp.com/app/answers/detail/a_id/622/kw/Dispute

您需要做的是创建自己的IPN模拟器来测试它。您可以创建一个基本的HTML表单，其操作设置为您的IPN URL，以及与您希望从IPN获得的名称/值匹配的隐藏字段。
这样您就可以在浏览器中加载测试并将其提交给您的IPN侦听器。您将能够在屏幕上看到有助于排除故障的结果。
请记住，以这种方式测试数据不是来自PayPal的服务器，因此IPN将未经验证。您需要确保您的代码逻辑处理该问题。
以下是您在退款时获得的一些IPN样本，以便您可以看到您应该期待的内容并相应地设置您的模拟器。
