=== Create {anomaly-jobs} API
++++
<titleabbrev>Create jobs</titleabbrev>
++++

Instantiates an {anomaly-job}.

[[ml-put-job-request]]
==== {api-request-title}

`PUT _ml/anomaly_detectors/<job_id>`

[[ml-put-job-prereqs]]
==== {api-prereq-title}

* If the {es} {security-features} are enabled, you must have `manage_ml` or
`manage` cluster privileges to use this API. See
<<security-privileges>>.

[[ml-put-job-desc]]
==== {api-description-title}

IMPORTANT: You must use {kib} or this API to create an {anomaly-job}. Do not put
a job directly to the `.ml-config` index using the {es} index API. If {es}
{security-features} are enabled, do not give users `write` privileges on the
`.ml-config` index.
