# Create a detection rule

- Server: `https://{kibana_url}`

## Paths

- `POST` `/api/detection_engine/rules`
- `POST` `/s/{space_id}/api/detection_engine/rules`

- [Api key auth](/elastic/docs-builder/docs/4371/api/doc/kibana/v8/authentication#apikeyauth)
- [Basic auth](/elastic/docs-builder/docs/4371/api/doc/kibana/v8/authentication#basicauth)

## Description

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

Create a new detection rule.
> warn
> When used with [API key](https://www.elastic.co/docs/deploy-manage/api-keys) authentication, the user's key gets assigned to the affected rules. If the user's key gets deleted or the user becomes inactive, the rules will stop running.

> If the API key that is used for authorization has different privileges than the key that created or most recently updated the rule, the rule behavior might change.

You can create the following types of rules:

* **Custom query**: Searches the defined indices and creates an alert when a document matches the rule's KQL query.
* **Event correlation**: Searches the defined indices and creates an alert when results match an [Event Query Language (EQL)](https://www.elastic.co/guide/en/elasticsearch/reference/current/eql.html) query.
* **Threshold**: Searches the defined indices and creates an alert when the number of times the specified field's value meets the threshold during a single execution. When there are multiple values that meet the threshold, an alert is generated for each value.
  For example, if the threshold `field` is `source.ip` and its `value` is `10`, an alert is generated for every source IP address that appears in at least 10 of the rule's search results. If you're interested, see [Terms Aggregation](https://www.elastic.co/guide/en/elasticsearch/reference/current/search-aggregations-bucket-terms-aggregation.html) for more information.
* **Indicator match**: Creates an alert when fields match values defined in the specified [Elasticsearch index](https://www.elastic.co/guide/en/elasticsearch/reference/current/indices-create-index.html). For example, you can create an index for IP addresses and use this index to create an alert whenever an event's `destination.ip` equals a value in the index. The index's field mappings should be [ECS-compliant](https://www.elastic.co/guide/en/ecs/current/ecs-reference.html).
* **New terms**: Generates an alert for each new term detected in source documents within a specified time range.
* **ES|QL**: Uses [Elasticsearch Query Language (ES|QL)](https://www.elastic.co/guide/en/elasticsearch/reference/current/esql.html) to find events and aggregate search results.
* **Machine learning rules**: Creates an alert when a machine learning job discovers an anomaly above the defined threshold.
> info
> To create machine learning rules, you must have the [appropriate license](https://www.elastic.co/subscriptions) or use a [cloud deployment](https://cloud.elastic.co/registration). Additionally, for the machine learning rule to function correctly, the associated machine learning job must be running.

To retrieve machine learning job IDs, which are required to create machine learning jobs, call the [Elasticsearch Get jobs API](https://www.elastic.co/guide/en/elasticsearch/reference/current/ml-get-job.html). Machine learning jobs that contain `siem` in the `groups` field can be used to create rules:

```json
...
"job_id": "linux_anomalous_network_activity_ecs",
"job_type": "anomaly_detector",
"job_version": "7.7.0",
"groups": [
  "auditbeat",
  "process",
  "siem"
],
...
```

Additionally, you can set up notifications for when rules create alerts. The notifications use the [Alerting and Actions framework](https://www.elastic.co/guide/en/kibana/current/alerting-getting-started.html). Each action type requires a connector. Connectors store the information required to send notifications via external systems. The following connector types are supported for rule notifications:

* Slack
* Email
* PagerDuty
* Webhook
* Microsoft Teams
* IBM Resilient
* Jira
* ServiceNow ITSM
> info
> For more information on PagerDuty fields, see [Send a v2 Event](https://developer.pagerduty.com/docs/events-api-v2/trigger-events/).

To retrieve connector IDs, which are required to configure rule notifications, call the [Find objects API](https://www.elastic.co/guide/en/kibana/current/saved-objects-api-find.html) with `"type": "action"` in the request payload.

- running - Rule execution started but not reached any intermediate or final status.
- partial failure - Rule can partially fail for various reasons either in the middle of an execution (in this case we update its status right away) or in the end of it. So currently this status can be both intermediate and final at the same time. A typical reason for a partial failure: not all the indices that the rule searches over actually exist.
- failed - Rule failed to execute due to unhandled exception or a reason defined in the business logic of its executor function.
- succeeded - Rule executed successfully without any issues. Note: this status is just an indication of a rule's "health". The rule might or might not generate any alerts despite of it.

  - `rule_id` (string)
    A stable unique identifier for the rule object. It can be assigned during rule creation. It can be any string, but often is a UUID.
