Get index settings

GET /{index}/_settings/{name}
GET /{index}/_settings
GET /_settings/{name}
GET /_settings

Get setting information for one or more indices. For data streams, it returns setting information for the stream's backing indices.

Authentication

Api key

Authorization: <value>

Elasticsearch APIs support key-based authentication. You must create an API key and use the encoded value in the request header. For example:

		curl -X GET "${ES_URL}/_cat/indices?v=true" \
  -H "Authorization: ApiKey ${API_KEY}"

To get API keys, use the /_security/api_key APIs.

Basic

Authorization: Basic <credentials>

Bearer

Authorization: Bearer <token>

Elasticsearch APIs support the use of bearer tokens in the Authorization HTTP header to authenticate with the API. For examples, refer to Token-based authentication services

Query parameters

allow_no_indices boolean · default: true

A setting that does two separate checks on the index expression. If false, the request returns an error (1) if any wildcard expression (including _all and *) resolves to zero matching indices or (2) if the complete set of resolved indices, aliases or data streams is empty after all expressions are evaluated. If true, index expressions that resolve to no indices are allowed and the request returns an empty result.

expand_wildcards string · default: open

Type of index that wildcard patterns can match. If the request can target data streams, this argument determines whether wildcard expressions match hidden data streams. Supports comma-separated values, such as open,hidden.

Supported values include:

all: Match any data stream or index, including hidden ones.
open: Match open, non-hidden indices. Also matches any non-hidden data stream.
closed: Match closed, non-hidden indices. Also matches any non-hidden data stream. Data streams cannot be closed.
hidden: Match hidden data streams and hidden indices. Must be combined with open, closed, or both.
none: Wildcard expressions are not accepted.

Values: all open closed hidden none

flat_settings boolean · default: false

If true, returns settings in flat format.

ignore_unavailable boolean · default: false

If false, the request returns an error if it targets a concrete (non-wildcarded) index, alias, or data stream that is missing, closed, or otherwise unavailable. If true, unavailable concrete targets are silently ignored.

include_defaults boolean · default: false

If true, return all default settings in the response.

local boolean · default: false deprecated

If true, the request retrieves information from the local node only. If false, information is retrieved from the master node.

master_timeout string · default: 30s

Period to wait for a connection to the master node. If no response is received before the timeout expires, the request fails and returns an error.
