The Slack Alert Method allows sending a predefined notification through Slack to notify Nobl9 users whenever an incident is triggered.


To set up the Slack integration, you’ll need to provide an Incoming Webhook URL. This allows Slack to send an automated notification to a channel of your choice. For details on where to find your Incoming Webhook URL, see the Slack documentation.

If you need any further help, contact your Slack administrator.

Configuring the Slack Alert Method

You can configure your Slack Alert Method directly in the Nobl9 UI, or by applying a YAML file in sloctl.

    This is your Incoming Webhook URL. It must start with For more information, refer to the Authentication section.
  1. Select a Project.
    Specifying a Project is helpful when multiple users are spread across multiple teams or projects. When the Project field is left blank then object is assigned to project default.
  2. Enter a Display Name.
    You can enter a friendly name with spaces in this field.
  3. Enter a Name.
    The name is mandatory and can only contain lowercase, alphanumeric characters and dashes (for example, my-alert-method-name). This field is populated automatically when you enter a display name, but you can edit the result.

    Here you can add details such as who is responsible for the integration (team/owner) and the purpose of creating it.
  5. Click the Add Alert Method button.
