+
+Instantiates a {dataframe-transform}.

+
+==== Request

+`PUT _data_frame/transforms/<data_frame_transform_id>`
+
+//===== Description
+
+==== Path Parameters
+
+`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.
+
+
+==== Request Body
+
+`source`:: The source index or index pattern.

+
+`pivot`:: Defines the pivot function `group by` fields and the aggregation to
+reduce the data.
+

+//==== Authorization
+
+==== Examples
+
+The following example creates a {dataframe-transform} for the {kib} eCommerce
+sample data:

+[source,js]
+--------------------------------------------------
+PUT _data_frame/transforms/ecommerce_transform
