==== {api-request-title}

`PUT _data_frame/transforms/<data_frame_transform_id>`

[[put-data-frame-transform-prereqs]]
==== {api-prereq-title}

* If the {es} {security-features} are enabled, you must have
`manage_data_frame_transforms` cluster privileges to use this API. The built-in
`data_frame_transforms_admin` role has these privileges. You must also
have `read` and `view_index_metadata` privileges on the source index and `read`,
`create_index`, and `index` privileges on the destination index. For more
information, see {stack-ov}/security-privileges.html[Security privileges] and
{stack-ov}/built-in-roles.html[Built-in roles].

[[put-data-frame-transform-desc]]
==== {api-description-title}

IMPORTANT:  You must use {kib} or this API to create a {dataframe-transform}.
            Do not put a {dataframe-transform} directly into any
            `.data-frame-internal*` indices using the Elasticsearch index API.
            If {es} {security-features} are enabled, do not give users any
            privileges on `.data-frame-internal*` indices.

[[put-data-frame-transform-path-parms]]
==== {api-path-parms-title}

`<data_frame_transform_id>`::
  (Required, string) Identifier for the {dataframe-transform}. This identifier
  can contain lowercase alphanumeric characters (a-z and 0-9), hyphens, and
  underscores. It must start and end with alphanumeric characters.

[[put-data-frame-transform-request-body]]
==== {api-request-body-title}

`description`::
  (Optional, string) Free text description of the {dataframe-transform}.

`dest`::
  (Required, object) Required. The destination configuration, which has the
  following properties:
  
  `index`:::
    (Required, string) The _destination index_ for the {dataframe-transform}.

  `pipeline`:::
    (Optional, string) The unique identifier for a <<pipeline,pipeline>>.

`frequency`::
  (Optional, time units) The interval between checks for changes in the source indices
  when the {dataframe-transform} is running continuously. Defaults to `1m`.
  The lowest permitted value is `1s`; the highest `1h`.

`pivot`::
  (Required, object) Defines the pivot function `group by` fields and the aggregation to
  reduce the data. See <<data-frame-transform-pivot>>.

`source`::
  (Required, object) The source configuration, which has the following
  properties:
  
  `index`:::
    (Required, string or array) The _source indices_ for the
    {dataframe-transform}. It can be a single index, an index pattern (for
    example, `"myindex*"`), or an array of indices (for example,
    `["index1", "index2"]`).
    
    `query`:::
      (Optional, object) A query clause that retrieves a subset of data from the
      source index. See <<query-dsl>>.
  
`sync`::
  (Optional, object) Defines the properties required to run continuously.
  `time`:::
    (Required, object) Specifies that the {dataframe-transform} uses a time
    field to synchronize the source and destination indices.
    `field`::::
      (Required, string) The date field that is used to identify new documents
      in the source.
+
--
TIP: In general, it’s a good idea to use a field that contains the
<<accessing-ingest-metadata,ingest timestamp>>. If you use a different field,
you might need to set the `delay` such that it accounts for data transmission
delays.

--
    `delay`::::
      (Optional, time units) The time delay between the current time and the
      latest input data time. The default value is `60s`.
