Integrate Endor Labs with Slack and automatically receive policy violations as notifications in your Slack channels. If you are using Slack for team communication and notifications, this integration helps you to seamlessly integrate Endor Labs into your organization’s existing workflows.

​
Create incoming webhooks in Slack

Create an incoming webhook to your Slack channel to enable Endor Labs to post notifications in the channel. The Incoming Webhook provides a unique URL to integrate your Slack channel in Endor Labs.
We recommend you designate a channel in your Slack workspace for receiving Endor Labs notifications and create an incoming webhook for that channel.
To create incoming webhooks in Slack:
  1. Create a Slack app for Endor Labs or use an existing app.
    • Click Create New App.
    • Choose From Scratch and Enter a name for the app, for example, Endor Labs.
    • Select your workspace and click Create App
    • You can enter basic, install, or display information for your Endor Labs app in Slack.
    • In Display Information, you can upload a logo and customize App colours to distinguish the Endor Labs App on the Slack workspace.
    • Click Save Changes.
  2. Navigate to Features, select Incoming Webhooks, and toggle Activate Incoming Webhooks.
  3. Refresh the page and click Add New Webhook to Workspace.
  4. Select a channel to receive Endor Labs findings in Post to, then select Authorize. If you need to add the incoming webhook to a private channel, you must first be in that channel.
  5. From Settings, copy the webhook URL under Webhook URLs for Your Workspace. Keep this URL handy to enter in Endor Labs.
For details on creating incoming webhooks in Slack, see Slack Integration

Associate an action policy with a Slack notification

Users can create action policies to send a Slack notification when the conditions of a given policy are met. For example, if there is a critical or high vulnerability, send the findings to Slack. While creating an action policy, configure the following settings:
  • Select Choose an Action as Send Notification.
  • From SELECT NOTIFICATION TARGETS, choose the Slack integration notification that you created.
  • Choose an Aggregation type for notifications.
    • Choose None (Notify for each Finding) to trigger a separate message for each finding.
    • Choose Project to group and send all the findings related to a project in one message.
    • Choose Dependency to send individual messages for every dependency.
    • Choose Dependency per package version to send individual messages for every unique combination of dependency and package version.
    You can see the top three findings from the highest available severity level. If fewer than three findings exist, only those are shown.
  • From Assign Scope, include the project tags in INCLUSIONS to apply this policy to a project.
See Create an action policy for more details.
