Slack Alerts Configuration

OpenMetadata integrates with Slack using Incoming Webhooks to deliver alert messages directly to your Slack channels. This allows you to receive real-time notifications without leaving Slack.

Setting Up a Slack Webhook

Follow these steps to create an Incoming Webhook in your Slack workspace:

Step 1: Access Slack API Applications

1. Go to Slack API Applications
2. Sign in with your Slack workspace credentials
3. Click Create New App or Create an App

Step 2: Create a New App

1. Select From scratch
2. Enter an App Name (e.g., "OpenMetadata Alerts")
3. Select your Slack Workspace
4. Click Create App

Step 3: Enable and Configure Incoming Webhooks

1. In the left sidebar, navigate to Incoming Webhooks
2. Toggle Activate Incoming Webhooks to On
3. Click Add New Webhook to Workspace
4. Select the Slack channel where you want alerts to be posted
5. Click Allow to authorize the app

Step 4: Copy Your Webhook URL

1. You'll now see your new webhook listed under Webhook URLs for Your Workspace
2. Copy the complete Webhook URL
3. Keep this URL safe - you'll need it to configure OpenMetadata

Configuring Slack Webhooks in OpenMetadata

Once you have your Slack Webhook URL, follow these steps to configure it in OpenMetadata:

Step 1: Access Alert Configuration

1. In OpenMetadata, navigate to Alerts & Notifications from the main menu
2. Select the type of alert you want to configure:
   • Data Observability Alerts (for data quality and pipeline monitoring)
   • System & Governance Notifications (for metadata and governance events)

Step 2: Add Slack as a Destination

1. Click Add Destination
2. Select Slack from the available destination options
3. Paste your Slack Webhook URL into the Slack Webhook URL field
4. Optionally, enter a Display Name for this Slack destination (e.g., "Data Quality Alerts")

Step 3: Test the Connection

1. Click Test Connection to verify the webhook is working
2. A test message will be sent to your Slack channel
3. If successful, you'll see a confirmation message

Step 4: Save and Enable

1. Click Save to store the configuration
2. The Slack destination is now ready to receive alerts

Best Practices

• Dedicated Channels: Create separate Slack channels for different types of alerts (e.g., #data-quality-alerts, #pipeline-failures)
• Channel Permissions: Ensure the Slack channel is accessible to all team members who need to receive alerts
• Multiple Webhooks: You can configure multiple Slack webhooks to send different alert types to different channels
• Monitoring: Regularly monitor your Slack channels to ensure alerts are being delivered
