=== Get {transform} API

Retrieves configuration information about one or more {transforms}.
The API accepts a +{request}+ object and returns a +{response}+.

[id="{upid}-{api}-request"]
==== Get {transform} request

A +{request}+ requires either a {transform} ID, a comma separated list
of ids or the special wildcard `_all` to get all {transforms}.

{transforms} to skip. `size` specifies the maximum number of
{transforms} to get. Defaults to `0` and `100` respectively.
<2> Whether to ignore if a wildcard expression matches no {transforms}.
<3> Optional boolean value for requesting the {transform} in a format that can
then be put into another cluster. Certain fields that can only be set when
the {transform} is created are removed.
