# Configure a Slack webhook (Classic)

:::caution
This Slack webhook configuration is part of Instance Notifications (Classic). [Event Notifications (Beta)](event-notifications) replaces this system. The new Event Notifications system supports direct webhook delivery to Slack (and other services) without requiring team-level Slack configuration.

For new integrations, Replicated recommends using [Configure and test webhooks (Beta)](event-notifications-webhooks) instead.

As a vendor, anyone on your team can set up Slack notifications to a shared Slack channel. Notifications give your team visibility into customer instance statuses and changes.

Notifications can help catch problems before they happen and let you proactively contact customers to prevent support cases. For example, you can be notified of a degraded status and you can contact your customer about fixing it before the instance goes down. This approach can make issues quicker and easier to solve, and improve the customer experience with less down time.

For more information about how application status is determined, see [Resource Statuses](insights-app-status#resource-statuses) in _Enabling and Understanding Application Status_. For more information about events that might trigger notifications, see [How the Vendor Portal Generates Events and Insights](instance-insights-event-data#about-events) in _About Instance and Event Data_.

While email notifications are specific to each user, the entire team can view and edit Slack notification settings. Any changes made by a team member impacts the team.

## Limitations

The following limitations apply to classic Slack webhook configuration:

- Teams can configure only one Slack channel.

- RBAC policies are not supported for configuring granular permissions.

## Prerequisite

Create a Slack webhook URL. For more information, see [Sending Messages using Incoming Webhooks](https://api.slack.com/messaging/webhooks) in the Slack API documentation.

Make sure to keep the URL secure because it contains a Secret that allows write access to one or more channels in your Slack Workspace.

## Configure the webhook in the Vendor Portal

When you enable Slack notifications for a team, you must first configure the Slack webhook in the Vendor Portal. Typically you do this one time. Then you can configure notifications for individual customer instances.

To configure the Slack webhook:

1. From the **[Team Vendor Portal](https://vendor.replicated.com/team/members)** page, click **Slack Notifications**.

1. On the **Slack Notifications Setup** page, paste the Slack webhook URL. Click **Save**.
