在罗马教廷式Webhook侦听器中侦听并获取触发操作的信息

Question

我已在仪表板中配置了PayPal Webhook侦听器，使其具有要侦听的必要事件，并且Webhook URL已成功触发，但是我无法在Webhook URL中获得所需的必要信息，例如订阅信息，订阅所有者等

我试图从webhook URL中获取信息，我得到的只是     {“名称”：“ INVALID_RESOURCE_ID”，“消息”：“未找到请求的资源ID”，“ debug_id”：“ ce4418e9be87”，“详细信息”：[]，“链接”：[]}

?>

我希望结果是订户的完整信息，例如电子邮件，全名，订阅期
