Configuring Webhook Settings

Overview

Developers can configure URLs of third-party systems on the Webhook page and subscribe to events such as branch push and tag push of CodeArts Repo based on project requirements. When a subscribed event occurs, you can use a webhook to send a POST request to the URL of a third-party system to trigger corresponding operations (in the third-party system), such as popping up a notification window, building or updating images, or performing deployment.

Before configuring a merge request rule, check Constraints. If you have the configuration permission, configure the rule based on Configuring Webhook Settings. For details about the configuration example, see Related Document.
