+> [!WARNING]
+> The Zoom Incoming Webhook app instance is bound to the Zoom account of the user who created it. When that user's Zoom account is deleted or deactivated, Zoom will automatically clean up all app instances installed by that user, including the Incoming Webhook. As a result, the previously generated `Endpoint` address (Webhook URL) will become **immediately invalid**, and Flashduty will no longer be able to send notifications to that Zoom channel.
+>
+> **Recommendation**: Use a shared team account or service account to create the Incoming Webhook connection, to avoid notification disruptions caused by individual account changes. If the creator's account has been deleted, another member must reinstall the Incoming Webhook app and reconfigure the Webhook URL and Verify Token in Flashduty.

+> [!WARNING]
+> Zoom 的 Incoming Webhook 应用实例与创建者的 Zoom 账号绑定。当创建者的 Zoom 账号被删除或停用时，Zoom 会默认清理该用户安装的所有应用实例，包括 Incoming Webhook。此时，之前生成的 `Endpoint` 地址（Webhook URL）将**立即失效**，Flashduty 将无法继续向该 Zoom 频道推送通知。
+>
+> **建议**：使用团队公共账号或服务账号来创建 Incoming Webhook 连接，避免因个人账号变动导致通知中断。如果创建者账号已被删除，需要由其他成员重新安装 Incoming Webhook 应用并重新配置 Flashduty 中的 Webhook 地址和 Verify Token。
