I. Intro

Webhook triggers are used to send messages between apps and Lark, improving the user experience within the platform. The Webhook function in Lark Flow provides a URL, and by setting this URL in another app that supports Webhook message notifications, you can send messages from the app to Lark Flow. For more information about how to use Lark Flow, see Workplace | How to use Lark Flow

Papertrail provides the Webhook method to send notifications for alarms set by users, see the Papertrail Webhook official documentation. Lark Flow is a tool to create a workflow that allows you to summarize all external information in Lark.
