`GET _transform/<transform_id>,<transform_id>` +
`GET _transform/` +
`GET _transform/_all` +
`GET _transform/*`
[[get-transform-prereqs]]
==== {api-prereq-title}
* 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 <<security-privileges>> and <<built-in-roles>>.
[[get-transform-desc]]
==== {api-description-title}
You can get information for multiple {transforms} in a single API
request by using a comma-separated list of identifiers or a wildcard expression.
You can get information for all {transforms} by using `_all`, by
specifying `*` as the `<transform_id>`, or by omitting the `<transform_id>`.
[[get-transform-path-parms]]
==== {api-path-parms-title}
`<transform_id>`::
(Optional, string) Identifier for the {transform}. It can be a
{transform} identifier or a wildcard expression. If you do not
specify one of these options, the API returns information for all
{transforms}.
[[get-transform-query-parms]]
==== {api-query-parms-title}
`allow_no_match`::
(Optional, boolean) Specifies what to do when the request:
+
--
* Contains wildcard expressions and there are no {transforms} that match.
* Contains the `_all` string or no identifiers and there are no matches.
* Contains wildcard expressions and there are only partial matches.
The default value is `true`, which returns an empty `transforms` array when
there are no matches and the subset of results when there are partial matches.
If this parameter is `false`, the request returns a `404` status code when there
are no matches or only partial matches.
--
`from`::
(Optional, integer) Skips the specified number of {transforms}. The
default value is `0`.
`size`::
(Optional, integer) Specifies the maximum number of {transforms} to obtain. The default value is `100`.
[[get-transform-response]]
==== {api-response-body-title}
`transforms`::
(array) An array of {transform} resources, which are sorted by the `id` value in
ascending order. See <<transform-resource>>.
[[get-transform-response-codes]]
==== {api-response-codes-title}
`404` (Missing resources)::
If `allow_no_match` is `false`, this code indicates that there are no
resources that match the request or only partial matches for the request.
[[get-transform-example]]
==== {api-examples-title}
The following example retrieves information about a maximum of ten {transforms}:
[source,console]
--------------------------------------------------
GET _transform?size=10
--------------------------------------------------
// TEST[skip:setup kibana sample data]
The following example gets configuration information for the
`ecommerce_transform` {transform}:
[source,console]
--------------------------------------------------
GET _transform/ecommerce_transform
--------------------------------------------------
// TEST[skip:setup kibana sample data]
The API returns the following results:
