You can bulk create, update, and delete rules.


Bulk createedit

This API has been deprecated since version 8.2, and is scheduled for end of life in Q4 2023. Please use the bulk action API instead.

This API supports Token-based authentication only.

Creates new rules.

Request URLedit

POST <kibana host>:<port>/api/detection_engine/rules/_bulk_create

Request bodyedit

A JSON array of rules, where each rule contains the required fields.

Response codeedit
200
Indicates a successful call.
Response payloadedit

A JSON array that includes a unique ID for each rule. A unique rule ID is generated for all rules that did not include a rule_id field.


Bulk deleteedit

This API has been deprecated since version 8.2, and is scheduled for end of life in Q4 2023. Please use the bulk action API instead.

Deletes multiple rules.

Request URLedit

DELETE <kibana host>:<port>/api/detection_engine/rules/_bulk_delete

Request bodyedit

A JSON array of id or rule_id fields of the rules you want to delete.

Example requestedit
DELETE api/detection_engine/rules/_bulk_delete
[
  {
    "rule_id": "process_started_by_ms_office_program_possible_payload"
  },
  {
    "id": "51658332-a15e-4c9e-912a-67214e2e2359"
  }
]
Response codeedit
200
Indicates a successful call.
Response payloadedit

A JSON array containing the deleted rules.


Bulk updateedit

This API has been deprecated since version 8.2, and is scheduled for end of life in Q4 2023. Please use the bulk action API instead.

This API supports Token-based authentication only.

Updates multiple rules.

You can use PUT or PATCH methods to bulk update rules, where:

  • PUT replaces the original rule and deletes fields that are not specified.
  • PATCH updates the specified fields.
Request URLedit

PUT <kibana host>:<port>/api/detection_engine/rules/_bulk_update

PATCH <kibana host>:<port>/api/detection_engine/rules/_bulk_update

Request bodyedit

A JSON array where each element includes:

  • The id or rule_id field of the rule you want to update.
  • The fields you want to modify.

If you call PUT to update rules, all unspecified fields are deleted. You cannot modify the id or rule_id values.

For PATCH calls, any of the fields can be modified. For PUT calls, some fields are required (see Update rule for a list of required fields).

Example requestedit
PATCH api/detection_engine/rules/_bulk_update

Bulk actionedit

Applies a bulk action to multiple rules. The bulk action is applied to all rules that match the filter or to the list of rules by their IDs.

Request URLedit

POST <kibana host>:<port>/api/detection_engine/rules/_bulk_action

URL query parametersedit
Name Type Description Required

dry_run

Boolean

Enables dry run mode for the request call.

No

Request bodyedit

A JSON object with the following properties:

Name Type Description Required

query

String

A KQL search query to match the rules.

No

ids

String[]

Array of rule IDs to which a bulk action will be applied. Only valid when query property is undefined.

No

action

  • edit

Yes

edit

BulkEditAction[]

Edit object that describes applying an update action.

No.

Yes, if action is edit.

Dry run modeedit

Enable dry run mode to verify that bulk actions can be applied to specified rules. Certain rules, such as prebuilt Elastic rules, can’t be edited and will return errors in the request response. Error details will contain an explanation, the rule name and/or ID, and additional troubleshooting information.

To enable dry run mode on a request, add the query parameter dry_run=true to the end of the request URL. Rules specified in the request will be temporarily updated. These updates won’t be written to Elasticsearch.

Dry run mode is not supported for the export bulk action. A 400 error will be returned in the request response.

BulkEditAction objectedit

  • type field: enum. Defines what will be updated in rules.
  • value field: any. value which will be applied in edit action.

Example 2, Partial failure

The following request adds tags tag-1 and tag-2 to the rules that have the IDs sent in the payload:

POST api/detection_engine/rules/_bulk_action
{
  "ids":[
    "8bc7dad0-9320-11ec-9265-8b772383a08d",
    "8e5c1a40-9320-11ec-9265-8b772383a08d",
  ],
  "action": "edit",
  "edit": [{ action: "add_tags", value:["tag-1", "tag-2"] }]
}
Response codeedit
500
Indicates partial bulk action failure.
Response payloadedit

If processing of any rule fails, a partial error outputs the ID and/or name of the affected rule and the corresponding error, as well as successfully processed rules (in the same format as a successful 200 request).

Example 3, Dry run

The following request will validate that the add_index_patterns bulk action can be successfully applied to three rules. Each rule (specified by its rule ID) is different: one is a prebuilt Elastic rule, another is a custom machine learning rule, and another is a custom query rule. Because dry run mode is enabled, changes to these rules will not be permanent or saved to Elasticsearch.

POST api/detection_engine/rules/_bulk_action?dry_run=true

    "action": "edit",
    "edit": [
        {
            "value": [

Response codeedit
500
Indicates a partial bulk action failure.
Response payloadedit

The attributes.errors section of the response shows that two rules failed to update and one succeeded. The same results would be returned if you ran the request without dry run mode enabled. Notice that there are no arrays in attributes.results. In dry run mode, rule updates are not applied and saved to Elasticsearch, so the endpoint wouldn’t return results for rules that have been updated, created, or deleted.
