[id="{upid}-{api}"]
=== Create or update index template API

[id="{upid}-{api}-request"]
==== Request

A +{request}+ specifies the `name` of a template and `patterns`
which controls whether the template should be applied to the new index.

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests-file}[{api}-request]
--------------------------------------------------
<1> The name of the template
<2> The patterns of the template

==== Settings
The settings of the template will be applied to the new index whose name matches the
template's patterns.

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests-file}[{api}-request-settings]
--------------------------------------------------
<1> Settings for this template

[[java-rest-high-put-template-request-mappings]]
==== Mappings
The mapping of the template will be applied to the new index whose name matches the
template's patterns.

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests-file}[{api}-request-mappings-json]
--------------------------------------------------
<1> The mapping, provided as a JSON string

The mapping source can be provided in different ways in addition to the
`String` example shown above:

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests-file}[{api}-request-mappings-map]
--------------------------------------------------
<1> Mapping source provided as a `Map` which gets automatically converted
to JSON format

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests-file}[{api}-request-mappings-xcontent]
--------------------------------------------------
<1> Mapping source provided as an `XContentBuilder` object, the Elasticsearch
built-in helpers to generate JSON content

==== Aliases
The aliases of the template will define aliasing to the index whose name matches the
template's patterns. A placeholder `{index}` can be used in an alias of a template.

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests-file}[{api}-request-aliases]
--------------------------------------------------
<1> The alias to define
<2> The alias to define with placeholder

==== Order
In case multiple templates match an index, the orders of matching templates determine
the sequence that settings, mappings, and alias of each matching template is applied.
Templates with lower orders are applied first, and higher orders override them.

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests-file}[{api}-request-order]
--------------------------------------------------
<1> The order of the template

==== Version
A template can optionally specify a version number which can be used to simplify template
management by external systems.

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests-file}[{api}-request-version]
--------------------------------------------------
<1> The version number of the template

==== Providing the whole source
The whole source including all of its sections (mappings, settings and aliases)
can also be provided:

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests-file}[{api}-whole-source]
--------------------------------------------------
<1> The source provided as a JSON string. It can also be provided as a `Map`
or an `XContentBuilder`.

==== Optional arguments
The following arguments can optionally be provided:

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests-file}[{api}-request-create]
--------------------------------------------------
<1> To force to only create a new template; do not overwrite the existing template

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests-file}[{api}-request-masterTimeout]
--------------------------------------------------
<1> Timeout to connect to the master node as a `TimeValue`
<2> Timeout to connect to the master node as a `String`

include::../execution.asciidoc[]

[id="{upid}-{api}-response"]
==== Response

The returned +{response}+ allows to retrieve information about the
executed operation as follows:

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests-file}[{api}-response]
--------------------------------------------------
<1> Indicates whether all of the nodes have acknowledged the request
