`POST /api/attack_discovery/_bulk`

**Spaces method and path for this operation:**

<div><span class="operation-verb post">post</span>&nbsp;<span class="operation-path">/s/{space_id}/api/attack_discovery/_bulk</span></div>

Refer to [Spaces](https://www.elastic.co/docs/deploy-manage/manage-spaces) for more information.

Performs bulk updates on multiple Attack discoveries, including workflow status changes and visibility settings. This endpoint allows efficient batch processing of alert modifications without requiring individual API calls for each alert.

## Request body

- object
  - `update` object, required — Configuration object containing all parameters for the bulk update operation
    - `enable_field_rendering` boolean — Enables a markdown syntax used to render pivot fields, for example `{{ user.name james }}`. When disabled, the same example would be rendered as `james`. This is primarily used for Attack Discovery views within Kibana. Defaults to `false`.
    - `ids` string[], required — Array of Attack Discovery IDs to update
    - `kibana_alert_workflow_status` 'open' | 'acknowledged' | 'closed' — When provided, update the kibana.alert.workflow_status of the attack discovery alerts
    - `visibility` 'not_shared' | 'shared' — When provided, update the visibility of the alert, as determined by the kibana.alert.attack_discovery.users field
    - `with_replacements` boolean — When true, returns the updated Attack discoveries with text replacements applied to the detailsMarkdown, entitySummaryMarkdown, summaryMarkdown, and title fields. This substitutes anonymized values with human-readable equivalents. Defaults to `true`.
