Slack

The Slack integration delivers real-time notifications from Interlynk to your Slack channels via incoming webhooks.

Purpose

• Receive notifications for vulnerability discoveries, policy violations, license issues, and SBOM uploads.

• Route notifications to specific channels based on severity or event type.

Setup Steps

1. Navigate to Settings > Organization > Integrations.

2. Click Slack.

3. Click Add New to add a Slack webhook configuration.

4. Enter:

   • Slack Webhook URL: An incoming webhook URL from your Slack workspace.

   • Notification Type: Select the notification level:

     • All — Receive all notifications.

     • Alert — Only alert-level notifications.

     • Warning — Only warning-level notifications.

     • Info — Only informational notifications.

   • Frequency: Currently supports Instant delivery.

5. Click Save.

Multiple Channels

You can add multiple Slack webhook configurations to route different notification types to different channels. For example:

• #security-alerts — Alert notifications only

• #sbom-updates — Info notifications for uploads

• #all-interlynk — All notifications

Click Add New to add additional rows.

Channel Configuration

Creating a Slack Webhook URL

1. In Slack, navigate to Apps > Manage > Custom Integrations > Incoming Webhooks (or use the Slack API at api.slack.com/apps).

2. Create a new incoming webhook.

3. Select the target channel.

4. Copy the generated webhook URL (format: https://hooks.slack.com/services/T.../B.../...).

5. Paste the URL into the Interlynk Slack integration configuration.

Event Types

Notifications are categorized into the following types:

Category	Examples
Vulnerabilities	New critical/high vulnerability discovered, severity change
Licenses	License compliance violation detected
Policies	Policy scan completed with failures
Uploads	SBOM uploaded and processed

Message Formatting

Slack messages from Interlynk include:

• Event type and severity level

• Affected product and environment

• Summary of the event (e.g., vulnerability ID, component name)

• Link back to the relevant Interlynk dashboard page

Required Permissions

Slack Workspace

• Permission to create incoming webhooks in the target workspace.

Interlynk

Permission	Purpose
view_connections	View Slack integration settings
edit_connections	Add or update Slack webhooks
delete_connections	Remove Slack webhook configurations

Security Notes

• Webhook URLs are encrypted at rest.

• Slack webhook URLs are secret — treat them like API tokens. Do not commit them to source control.

• Validate that the webhook URL points to your intended Slack workspace before saving.

• If a webhook URL is compromised, regenerate it in Slack and update the Interlynk configuration.

Troubleshooting

Issue	Cause	Resolution
No messages in channel	Invalid webhook URL	Verify the URL is correct and the webhook is active in Slack
Messages going to wrong channel	Webhook configured for different channel	Create a new webhook for the correct channel
Duplicate notifications	Multiple webhook configs with same URL	Remove duplicate entries in the integration settings
Webhook URL rejected	URL format invalid	Ensure the URL matches https://hooks.slack.com/services/...
