=== Stop {ilm} API

[subs="attributes"]
++++
<titleabbrev>Stop {ilm}</titleabbrev>
++++

Stop the {ilm} ({ilm-init}) plugin.

==== Request

`POST /_ilm/stop`

==== Description

Halts all lifecycle management operations and stops the {ilm-init} plugin. This
is useful when you are performing maintenance on the cluster and need to prevent
{ilm-init} from performing any actions on your indices.

The API returns as soon as the stop request has been acknowledged, but the
plugin might continue to run until in-progress operations complete and the plugin
can be safely stopped. Use the  <<ilm-get-status, Get ILM Status>> API to see
if {ilm-init} is running.

==== Request Parameters

include::{docdir}/rest-api/common-parms.asciidoc[tag=timeoutparms]

==== Authorization

You must have the `manage_ilm` cluster privilege to use this API.
For more information, see {stack-ov}/security-privileges.html[Security Privileges].

==== Examples

The following example stops the ILM plugin.
