Notification Templates

Templates control the format of notifications. Separate templates exist for each delivery channel (Email, Slack, Teams) and for each delivery type (single and batch). The default templates for each channel integrate Guardrails Quick Actions and serve as a great jumping off point for your own customization.

Slack Notification Example

Email Notification Example

Individual Email Notification

Batch Email Notification Example

Batch Email Notification

The default templates can be overridden by setting the following policies:

Turbot > Notifications > Email > Action Template > Subject
Turbot > Notifications > Email > Action Template > Body
Turbot > Notifications > Email > Action Template > Batch Subject
Turbot > Notifications > Email > Action Template > Batch Body


Turbot > Notifications > Email > Control Template > Subject
Turbot > Notifications > Email > Control Template > Body
Turbot > Notifications > Email > Control Template > Batch Subject
Turbot > Notifications > Email > Control Template > Batch Body


Turbot > Notifications > Slack > Action Template > Body
Turbot > Notifications > Slack > Action Template > Batch Body


Turbot > Notifications > Slack > Control Template > Body
Turbot > Notifications > Slack > Control Template > Batch Body


Turbot > Notifications > Microsoft Teams > Action Template > Body
Turbot > Notifications > Microsoft Teams > Action Template > Batch Body


Turbot > Notifications > Microsoft Teams > Control Template > Body

Template Definition

Template syntax should be familiar for anyone that has written a Guardrails calculated policy. Each template consists of a GraphQL query and a Nunjucks template definition. Here is a simple example for the email subject template:

{% input %}
query notificationDetails($filter: [String!], $resourceId: ID!) {
  workspaceUrl: policyValue(
    uri: "tmod:@turbot/turbot#/policy/types/workspaceUrl"
    resourceId: $resourceId
  ) {
    value
  }
  notifications(filter: $filter) {
    items {
      notificationType
      message
      resource {
        turbot {
          id
        }
        trunk {
          title
        }
      }
      turbot {
        createTimestamp
      }
    }
  }
}
{% endinput %}


{%- if domain %}
    {% set workspace = domain.split('/')[2].split('.')[0] %}
    [{{ workspace }}] {{ $.notifications.items.length }} actions by Turbot
{%- else %}
    {{ $.notifications.items.length }} actions by Turbot
{%- endif %}

The GraphQL query is contained between the {% input %} and {% endinput %} tags. GraphQL is not case sensitive.

All content after {% endinput %} is the template. Keep in mind that Nunjucks flow logic (e.g. {% if domain %}) can generate newlines or whitespace. For template sections where extra newlines would be problematic (e.g. the email subject) make sure that you use whitespace control features of Nunjucks (i.e. {%- if domain -%}) does not generate newlines or excess whitespace, or keep all logic on a single line.

Example Email Body Template

{% input %}
query controlGet($id: ID!, $resourceId: ID!, $filter: [String!]) {
  workspaceUrl: policyValue(uri: "tmod:@turbot/turbot#/policy/types/workspaceUrl", resourceId:$resourceId){
      value
    }
  oldControl: control(id: $id) {
    actor {
      identity {
        picture
        turbot {
          title
          id
        }
      }
    }
    state
    reason
    details
    type {
      trunk {
        title
      }
    }
    turbot {
      createTimestamp
      updateTimestamp
      id
    }
    resource {
      turbot {
        id
      }
      trunk {
        title
      }
      type {
        title
      }
    }
  }
  quickActions: controlTypes(filter: $filter) {
    items {
      actionTypes{
        items{
          title
          icon
          description
          uri
          confirmationType
          defaultActionPermissionLevels
          turbot {
            id
          }
        }
      }
    }
  }
}
