# Send notifications using Slack

You can notify your User Group members using Slack as one of the notification channels. To do this, add a Slack Incoming Webhook into your Harness User Groups' [Notification Preferences](/harness-platform/use-harness-platform/platform-access-control/add-user-groups.md#edit-notification-preferences).

Then you can add your User Group to a Notification Strategy and receive alert info in Slack.

#### Step 1: Create a Slack App and Webhook for Your Channel <a href="#step-1-create-a-slack-app-and-webhook-for-your-channel" id="step-1-create-a-slack-app-and-webhook-for-your-channel"></a>

Follow the steps in Slack documentation for creating a Slack app, selecting your channel, and creating a webhook: [Sending messages using Incoming Webhooks](https://api.slack.com/messaging/webhooks).

When you are done, you'll have a webhook that looks something like this:

#### Step 2: Add the Webhook to the User Group Notification Preferences <a href="#step-2-add-the-webhook-to-the-user-group-notification-preferences" id="step-2-add-the-webhook-to-the-user-group-notification-preferences"></a>

1. In your **Account**/**Organization**/**Project** click Access Control.
2. Click **User Groups**.
3. Select the User Group to which you want to add notification preferences.
4. In **Notification Preferences**, select **Slack Webhook URL**.
5. Paste the Webhook into **Slack Webhook URL** or add it as an [Encrypted Text](/harness-platform/use-harness-platform/secrets/add-use-text-secrets.md) in Harness and reference it here.\
   For example, if you have a text secret with the identifier slackwebhookURL, you can reference it like this:

```
<+secrets.getValue("slackwebhookURL")>​​
```

You can reference a secret within the Org scope using an expression with `org`:​

```
<+secrets.getValue("org.your-secret-Id")>​
```

You can reference a secret within the Account scope using an expression with `account`:​

```
<+secrets.getValue("account.your-secret-Id")>​
```

6. Click **Save**.![](/files/958E8QsOFb6nY93LylNJ)

Now your Slack channel will be used to notify this User Group of alerts.
