php - 用于争议/拒付的 PayPal IPN

Question

因此，我正在使用 PayPal IPN 为我的商店项目中的支付网关。用户可以创建商店并添加一个仅存储其 PayPal 电子邮件的贝宝网关。

我如何收听该付款的退款，以便我可以采取行动。请注意，我显然无权访问这些贝宝账户，因此我无法在他们的贝宝中设置监听器。

当我创建付款时，我正在构建一个查询，然后将它们发送到该 URL，在该查询中是 notify_url，如果有人要对付款产生争议，它将再次使用。我试图引起争议，但是我的数据库似乎没有发生任何事情（通知网址的作用）。

任何帮助都会很棒。这是我正在使用的 codeigniter 库：
