Paypal 沙盒取消 webhook 不起作用

Question

Paypal 沙箱中用于订阅激活 BILLING.SUBSCRIPTION.ACTIVATED 的 Webhook 效果非常好。

尽管如此，当我尝试从客户沙箱帐户取消订阅时，没有收到 webhook 帖子。

应该是“计费.订阅.取消”。

事实上，沙盒管理员帐户的状态为“待处理”：

是否要等到订阅结束日期才能发送取消消息？ 还是出于安全考虑会等待几个小时？

以下是 paypal 沙箱网站的详细信息：

Answer 1

待处理表示正在等待传送到订阅的 Webhook URL。事件发生，并尝试传送到 URL，但该 URL 未响应 HTTP 200 成功消息，以便将 Webhook 标记为已成功传送。事实上，根据您问题中记录的详细信息：

        "webhook_url": "https://www.myapp.com/webhook",
        "http_status": 440,

该 URL 相反以 HTTP 440 状态进行响应

假设 URL 正确并且您针对此问题将其更改为“myapp”，则问题是您需要调试该 URL 处的端点/代码，以便在将 Webhook 交付发布到该 URL 时它会响应 200 成功状态。然后他们的状态将不再是 Pending。

Answer 2

尽管如此，当我尝试取消订阅时 客户沙箱帐户，未收到 webhook 帖子。

当通过仪表板取消订阅时，我可以理解“没有收到 webhook 帖子”。你成功了吗？根据我的阅读，似乎 BILLING.SUBSCRIPTION.CANCELLED 不是通过仪表板取消触发的。只有 IPN 是，但这些已被弃用。
