beta[]

Retrieves configuration information for {dataframe-transforms}.


==== Request

`GET _data_frame/transforms/<data_frame_transform_id>` +

`GET _data_frame/transforms/<data_frame_transform_id>,<data_frame_transform_id>` +

`GET _data_frame/transforms/` +

`GET _data_frame/transforms/_all` +

`GET _data_frame/transforms/*`

//===== Description

==== Path Parameters

`data_frame_transform_id`::
  (string) Identifier for the {dataframe-transform}. It can be a
  {dataframe-transform} identifier or a wildcard expression. If you do not
  specify one of these options, the API returns information for all
  {dataframe-transforms}.

==== Query Parameters

`from`::
      (integer) Skips the specified number of {dataframe-transforms}. The
      default value is `0`.

`size`::
      (integer) Specifies the maximum number of {dataframe-transforms} to obtain. The default value is `100`.

`allow_no_match`::
  (boolean) Whether to ignore if a wildcard expression matches no data frame transforms.
  This includes `_all` string or when no transforms have been specified. The default is `true`.

==== Results

The API returns the following information:

`transforms`::
  (array) An array of transform resources, which are sorted by the `id` value in
  ascending order.

==== Authorization

If the {es} {security-features} are enabled, you must have
`monitor_data_frame_transforms` cluster privileges to use this API. The built-in
`data_frame_transforms_user` role has these privileges. For more information,
see {stack-ov}/security-privileges.html[Security privileges] and
{stack-ov}/built-in-roles.html[Built-in roles].

==== Examples

The following example retrieves information about a maximum of ten transforms:

[source,js]
--------------------------------------------------
GET _data_frame/transforms?size=10
--------------------------------------------------
// CONSOLE
// TEST[skip:setup kibana sample data]

The following example gets configuration information for the
`ecommerce_transform` {dataframe-transform}:

[source,js]
--------------------------------------------------
GET _data_frame/transforms/ecommerce_transform
--------------------------------------------------
// CONSOLE
// TEST[skip:setup kibana sample data]

The API returns the following results:
