Set up email integration

Learn how to integrate your email addresses with Endor Labs and receive finding notifications

Integrate your email address with Endor Labs and automatically receive policy violations as email notifications.

Configure email integration

To configure an email integration, follow these steps:

  1. Sign in to Endor Labs and click Integrations from the left sidebar.
  2. Navigate to Email under Notifications and click Add.
  3. Click Add Notification Integration.
  4. Specify a name and description for this integration.
  5. Enter email addresses separated by commas in EMAIL ADDRESSES.
  6. Click Add Notification Integration.

Associate an action policy with the email notification

Users can create action policies to send an email notification when the conditions of a given policy are met. For example, if there is a critical or high vulnerability, send an email notification.

While creating an action policy, configure the following settings:

  • Select Choose an Action as Send Notification.
  • From SELECT NOTIFICATION TARGETS, choose the email integration notification that you created.
  • Choose an Aggregation type for notifications.
    • Choose Project to group and send the findings related to a project in one email.
    • Choose Dependency to send individual email messages for every dependency.
  • From Assign Scope, include the project tags in INCLUSIONS to apply this policy to a project.

See Create an action policy for more details.

Customize email notification templates

Endor Labs provides a default template with standard information that will be included in the email. You can use the default template or you can choose to edit and customize this template to fit your organization’s specific requirements. You can also create custom templates using Go Templates.

  1. Sign in to Endor Labs and navigate to Manage > Integrations.
  2. Look for Email under Notifications.
  3. Click Manage to view the list of configured notification integrations.
  4. Choose a notification integration and click the ellipsis on the right side, and click Edit Template.
  5. Make required changes to any of the following templates and click Save Template.
    • Open - This template is used when new notifications are raised.
    • Update - This template is used when an existing notification is updated, such as, when some findings for the notification are changed.
    • Resolve - This template is used when all the findings reported by the notification are resolved.
  6. Click Restore to Default to revert the changes.
  7. Use the download icon on the top right corner to download this template.
  8. Use the copy icon to copy the information in the template.

Data model

To create custom templates for email notifications, you must understand the data supplied to the template.

See the EmailData message used for Open and Update templates.

// EmailData contains mappings for findings and package versions that is to be published as
// an email. It also contains the NotificationData object in the payload.
type EmailData struct {
	Payload                      *endorpb.NotificationData
	PackageVersionFindingMapping map[string]map[string][]string
	PackageVersionMap            map[string]*endorpb.PackageVersion
	APIURL                       string
	APPURL                       string
	FromAddress                  string

See the ResolvedEmailData message used for Resolve template.

// ResolvedEmailData contains the data that's acessible in the resolved email template.
type ResolvedEmailData struct {
	APIURL      string
	APPURL      string
	Project     *endorpb.Project
	Policy      *endorpb.Policy
	ProjectName string

Run a scan

Run the endorctl scan on your configured projects. See endorctl scan commands for more information. You can view email notifications of policy violations in your inbox.
