=== Get mapping API
++++
<titleabbrev>Get mapping</titleabbrev>
++++

Retrieves <<mapping,mapping definitions>> for one or more indices. For data
streams, the API retrieves mappings for the stream's backing indices.

[source,console]
--------------------------------------------------
GET /twitter/_mapping
--------------------------------------------------
// TEST[setup:twitter]

NOTE: Before 7.0.0, the 'mappings' definition used to include a type name. Although mappings
in responses no longer contain a type name by default, you can still request the old format
through the parameter `include_type_name`. For more details, please see <<removal-of-types>>.


[[get-mapping-api-request]]
==== {api-request-title}

`GET /_mapping`

`GET /<target>/_mapping`


[[get-mapping-api-path-params]]
==== {api-path-parms-title}

`<target>`::
(Optional, string)
Comma-separated list of data streams, indices, and index aliases used to limit
the request. Wildcard expressions (`*`) are supported.
+
To target all data streams and indices in a cluster, omit this parameter or use
`_all` or `*`.

===== Multiple data streams and indices

The get mapping API can be used to get more than one data stream or index with a
single call. General usage of the API follows the following syntax:
`host:port/<target>/_mapping` where `<target>` can accept a comma-separated
list of names. To get mappings for all data streams and indices in a cluster, use `_all` or `*` for `<target>`
or omit the `<target>` parameter.
The following are some examples:

[source,console]
--------------------------------------------------
GET /twitter,kimchy/_mapping
--------------------------------------------------
// TEST[setup:twitter]
// TEST[s/^/PUT kimchy\nPUT book\n/]

If you want to get mappings of all indices in a cluster, the following
examples are equivalent:

[source,console]
--------------------------------------------------
GET /*/_mapping

GET /_all/_mapping

GET /_mapping
--------------------------------------------------
// TEST[setup:twitter]
