+A webhook is a way for an app to send notifications triggered by specific events. It delivers information to other applications in real time, allowing users to receive notifications immediately.
 
+This tutorial describes how to configure a webhook server to receive platform notifications.
+
+## Prerequisites
+
+You need an account granted the `platform-admin` role. For more information, see [Create Workspaces, Projects, Accounts and Roles](../../../../quick-start/create-workspace-and-project/).
+
+## Configure the Webhook Server
+
+1. Log in to the KubeSphere web console as the `platform-admin` user.
+
+2. Click **Platform** on the upper-left corner and select **Platform Settings**.
+
+3. In the left nevigation pane, click **Webhook** under **Notification Management**.
+
+4. On the **Webhook** page, configure your webhook server by filling in the text boxes. The parameters are described as follows:
+
+   - **URL**: URL of the webhook server.
+
+   - **Verification Type**: Select a verification method for security authentication.
+     - **No Auth**: Skip the authentication. It means that all notifications can be sent to the URL.
+     - **Bearer Token**: Add a token to the URL for unique identification.
+     - **Basic Auth**: Provide a username and password for authentication.
+
+   {{< notice note>}}Currently, Kubesphere does not suppot TLS connections (https). You need to select the checkbox on the left of **Skip TLS Certification** if you use https.
+
+   {{</notice>}}
