Elasticsearch provides REST APIs that are used by the UI components and can be called directly to configure and access Elasticsearch features.

Documentation source and versions

This documentation is derived from the main branch of the elasticsearch-specification repository. It is provided under license Attribution-NonCommercial-NoDerivatives 4.0 International. This documentation contains work-in-progress information for future Elastic Stack releases.

Last update on Aug 20, 2025.

This API is provided under license Apache 2.0.

Authentication

The API accepts 3 different authentication methods:

Api key auth (http_api_key)

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 auth (http)

Basic auth tokens are constructed with the Basic keyword, followed by a space, followed by a base64-encoded string of your username:password (separated by a : colon).

Example: send a Authorization: Basic aGVsbG86aGVsbG8= HTTP header with your requests to authenticate with the API.

Bearer auth (http)

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

Behavioral analytics

The behavioral analytics APIs let you create and manage analytics collections and view their data. Use them to analyze users’ search and click behavior, improve result relevance, and identify content gaps.

















Compact and aligned text (CAT)

The compact and aligned text (CAT) APIs aim are intended only for human consumption using the Kibana console or command line. They are not intended for use by applications. For application consumption, it's recommend to use a corresponding JSON API. All the cat commands accept a query string parameter help to see all the headers and info they provide, and the /_cat command alone lists all the available commands.













Get a document count Generally available

GET /_cat/count/{index}

All methods and paths for this operation:

GET /_cat/count

GET /_cat/count/{index}

Get quick access to a document count for a data stream, an index, or an entire cluster. The document count only includes live documents, not deleted documents which have not yet been removed by the merge process.

IMPORTANT: CAT APIs are only intended for human consumption using the command line or Kibana console. They are not intended for use by applications. For application consumption, use the count API.

Required authorization

  • Index privileges: read

Path parameters

  • index string | array[string] Required

    A comma-separated list of data streams, indices, and aliases used to limit the request. It supports wildcards (*). To target all data streams and indices, omit this parameter or use * or _all.

Query parameters

  • h string | array[string]

    A comma-separated list of columns names to display. It supports simple wildcards.

    Supported values include:

    • epoch (or t, time): The Unix epoch time in seconds since 1970-01-01 00:00:00.
    • timestamp (or ts, hms, hhmmss): The current time in HH:MM:SS format.
    • count (or dc, docs.count, docsCount): The document count in the cluster or index.

    Values are epoch, t, time, timestamp, ts, hms, hhmmss, count, dc, docs.count, or docsCount.

  • s string | array[string]

    List of columns that determine how the table should be sorted. Sorting defaults to ascending and can be changed by setting :asc or :desc as a suffix to the column name.

Responses

  • 200 application/json
    Hide response attributes Show response attributes object
    • epoch number | string

      Some APIs will return values such as numbers also as a string (notably epoch timestamps). This behavior is used to capture this behavior while keeping the semantics of the field type.

      Depending on the target language, code generators can keep the union or remove it and leniently parse strings to the target type.

      One of:

      Time unit for seconds

    • timestamp string

      Time of day, expressed as HH:MM:SS

    • count string

      the document count

GET /_cat/count/my-index-000001?v=true&format=json
resp = client.cat.count(
    index="my-index-000001",
    v=True,
    format="json",
)
const response = await client.cat.count({
  index: "my-index-000001",
  v: "true",
  format: "json",
});
response = client.cat.count(
  index: "my-index-000001",
  v: "true",
  format: "json"
)
$resp = $client->cat()->count([
    "index" => "my-index-000001",
    "v" => "true",
    "format" => "json",
]);
curl -X GET -H "Authorization: ApiKey $ELASTIC_API_KEY" "$ELASTICSEARCH_URL/_cat/count/my-index-000001?v=true&format=json"
client.cat().count();
Response examples (200)
A successful response from `GET /_cat/count/my-index-000001?v=true&format=json`. It retrieves the document count for the `my-index-000001` data stream or index.
[
  {
    "epoch": "1475868259",
    "timestamp": "15:24:20",
    "count": "120"
  }
]
A successful response from `GET /_cat/count?v=true&format=json`. It retrieves the document count for all data streams and indices in the cluster.
[
  {
    "epoch": "1475868259",
    "timestamp": "15:24:20",
    "count": "121"
  }
]












Get index information Generally available

GET /_cat/indices/{index}

All methods and paths for this operation:

GET /_cat/indices

GET /_cat/indices/{index}

Get high-level information about indices in a cluster, including backing indices for data streams.

Use this request to get the following information for each index in a cluster:

  • shard count
  • document count
  • deleted document count
  • primary store size
  • total store size of all shards, including shard replicas

These metrics are retrieved directly from Lucene, which Elasticsearch uses internally to power indexing and search. As a result, all document counts include hidden nested documents. To get an accurate count of Elasticsearch documents, use the cat count or count APIs.

CAT APIs are only intended for human consumption using the command line or Kibana console. They are not intended for use by applications. For application consumption, use an index endpoint.

Required authorization

  • Index privileges: monitor
  • Cluster privileges: monitor

Path parameters

  • index string | array[string] Required

    Comma-separated list of data streams, indices, and aliases used to limit the request. Supports wildcards (*). To target all data streams and indices, omit this parameter or use * or _all.

Query parameters

  • bytes string

    The unit used to display byte values.

    Values are b, kb, mb, gb, tb, or pb.

  • expand_wildcards string | array[string]

    The type of index that wildcard patterns can match.

    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 are all, open, closed, hidden, or none.

  • health string

    The health status used to limit returned indices. By default, the response includes indices of any health status.

    Supported values include:

    • green (or GREEN): All shards are assigned.
    • yellow (or YELLOW): All primary shards are assigned, but one or more replica shards are unassigned. If a node in the cluster fails, some data could be unavailable until that node is repaired.
    • red (or RED): One or more primary shards are unassigned, so some data is unavailable. This can occur briefly during cluster startup as primary shards are assigned.
    • unknown
    • unavailable

    Values are green, GREEN, yellow, YELLOW, red, RED, unknown, or unavailable.

  • include_unloaded_segments boolean

    If true, the response includes information from segments that are not loaded into memory.

  • pri boolean

    If true, the response only includes information from primary shards.

  • time string

    The unit used to display time values.

    Values are nanos, micros, ms, s, m, h, or d.

  • master_timeout string

    Period to wait for a connection to the master node.

    Values are -1 or 0.

  • h string | array[string]

    List of columns to appear in the response. Supports simple wildcards.

  • s string | array[string]

    List of columns that determine how the table should be sorted. Sorting defaults to ascending and can be changed by setting :asc or :desc as a suffix to the column name.

Get segment information Generally available

GET /_cat/segments/{index}

All methods and paths for this operation:

GET /_cat/segments

GET /_cat/segments/{index}

Get low-level information about the Lucene segments in index shards. For data streams, the API returns information about the backing indices. IMPORTANT: cat APIs are only intended for human consumption using the command line or Kibana console. They are not intended for use by applications. For application consumption, use the index segments API.

Required authorization

  • Index privileges: monitor
  • Cluster privileges: monitor

Path parameters

  • index string | array[string] Required

    A comma-separated list of data streams, indices, and aliases used to limit the request. Supports wildcards (*). To target all data streams and indices, omit this parameter or use * or _all.

Query parameters

  • bytes string

    The unit used to display byte values.

    Values are b, kb, mb, gb, tb, or pb.

  • h string | array[string]

    A comma-separated list of columns names to display. It supports simple wildcards.

    Supported values include:

    • index (or i, idx): The name of the index.
    • shard (or s, sh): The name of the shard.
    • prirep (or p, pr, primaryOrReplica): The shard type. Returned values are 'primary' or 'replica'.
    • ip: IP address of the segment’s shard, such as '127.0.1.1'.
    • segment: The name of the segment, such as '_0'. The segment name is derived from the segment generation and used internally to create file names in the directory of the shard.
    • generation: Generation number, such as '0'. Elasticsearch increments this generation number for each segment written. Elasticsearch then uses this number to derive the segment name.
    • docs.count: The number of documents as reported by Lucene. This excludes deleted documents and counts any nested documents separately from their parents. It also excludes documents which were indexed recently and do not yet belong to a segment.
    • docs.deleted: The number of deleted documents as reported by Lucene, which may be higher or lower than the number of delete operations you have performed. This number excludes deletes that were performed recently and do not yet belong to a segment. Deleted documents are cleaned up by the automatic merge process if it makes sense to do so. Also, Elasticsearch creates extra deleted documents to internally track the recent history of operations on a shard.
    • size: The disk space used by the segment, such as '50kb'.
    • size.memory: The bytes of segment data stored in memory for efficient search, such as '1264'. A value of '-1' indicates Elasticsearch was unable to compute this number.
    • committed: If 'true', the segments is synced to disk. Segments that are synced can survive a hard reboot. If 'false', the data from uncommitted segments is also stored in the transaction log so that Elasticsearch is able to replay changes on the next start.
    • searchable: If 'true', the segment is searchable. If 'false', the segment has most likely been written to disk but needs a refresh to be searchable.
    • version: The version of Lucene used to write the segment.
    • compound: If 'true', the segment is stored in a compound file. This means Lucene merged all files from the segment in a single file to save file descriptors.
    • id: The ID of the node, such as 'k0zy'.

    Values are index, i, idx, shard, s, sh, prirep, p, pr, primaryOrReplica, ip, segment, generation, docs.count, docs.deleted, size, size.memory, committed, searchable, version, compound, or id.

  • s string | array[string]

    A comma-separated list of column names or aliases that determines the sort order. Sorting defaults to ascending and can be changed by setting :asc or :desc as a suffix to the column name.

  • local boolean

    If true, the request computes the list of selected nodes from the local cluster state. If false the list of selected nodes are computed from the cluster state of the master node. In both cases the coordinating node will send requests for further information to each selected node.

Cluster

The cluster APIs enable you to retrieve information about your infrastructure on cluster, node, or shard level. You can manage cluster settings and voting configuration exceptions, collect node statistics and retrieve node information.





Update voting configuration exclusions Generally available; Added in 7.0.0

POST /_cluster/voting_config_exclusions

Update the cluster voting config exclusions by node IDs or node names. By default, if there are more than three master-eligible nodes in the cluster and you remove fewer than half of the master-eligible nodes in the cluster at once, the voting configuration automatically shrinks. If you want to shrink the voting configuration to contain fewer than three nodes or to remove half or more of the master-eligible nodes in the cluster at once, use this API to remove departing nodes from the voting configuration manually. The API adds an entry for each specified node to the cluster’s voting configuration exclusions list. It then waits until the cluster has reconfigured its voting configuration to exclude the specified nodes.

Clusters should have no voting configuration exclusions in normal operation. Once the excluded nodes have stopped, clear the voting configuration exclusions with DELETE /_cluster/voting_config_exclusions. This API waits for the nodes to be fully removed from the cluster before it returns. If your cluster has voting configuration exclusions for nodes that you no longer intend to remove, use DELETE /_cluster/voting_config_exclusions?wait_for_removal=false to clear the voting configuration exclusions without waiting for the nodes to leave the cluster.

A response to POST /_cluster/voting_config_exclusions with an HTTP status code of 200 OK guarantees that the node has been removed from the voting configuration and will not be reinstated until the voting configuration exclusions are cleared by calling DELETE /_cluster/voting_config_exclusions. If the call to POST /_cluster/voting_config_exclusions fails or returns a response with an HTTP status code other than 200 OK then the node may not have been removed from the voting configuration. In that case, you may safely retry the call.

NOTE: Voting exclusions are required only when you remove at least half of the master-eligible nodes from a cluster in a short time period. They are not required when removing master-ineligible nodes or when removing fewer than half of the master-eligible nodes.

External documentation

Query parameters

  • node_names string | array[string]

    A comma-separated list of the names of the nodes to exclude from the voting configuration. If specified, you may not also specify node_ids.

  • node_ids string | array[string]

    A comma-separated list of the persistent ids of the nodes to exclude from the voting configuration. If specified, you may not also specify node_names.

  • master_timeout string

    Period to wait for a connection to the master node.

    Values are -1 or 0.

  • timeout string

    When adding a voting configuration exclusion, the API waits for the specified nodes to be excluded from the voting configuration before returning. If the timeout expires before the appropriate condition is satisfied, the request fails and returns an error.

    Values are -1 or 0.

Clear cluster voting config exclusions Generally available; Added in 7.0.0

DELETE /_cluster/voting_config_exclusions

Remove master-eligible nodes from the voting configuration exclusion list.

External documentation

Query parameters

  • master_timeout string

    Period to wait for a connection to the master node.

    Values are -1 or 0.

  • wait_for_removal boolean

    Specifies whether to wait for all excluded nodes to be removed from the cluster before clearing the voting configuration exclusions list. Defaults to true, meaning that all excluded nodes must be removed from the cluster before this API takes any action. If set to false then the voting configuration exclusions list is cleared even if some excluded nodes are still in the cluster.

Update the cluster settings Generally available

PUT /_cluster/settings

Configure and update dynamic settings on a running cluster. You can also configure dynamic settings locally on an unstarted or shut down node in elasticsearch.yml.

Updates made with this API can be persistent, which apply across cluster restarts, or transient, which reset after a cluster restart. You can also reset transient or persistent settings by assigning them a null value.

If you configure the same setting using multiple methods, Elasticsearch applies the settings in following order of precedence: 1) Transient setting; 2) Persistent setting; 3) elasticsearch.yml setting; 4) Default setting value. For example, you can apply a transient setting to override a persistent setting or elasticsearch.yml setting. However, a change to an elasticsearch.yml setting will not override a defined transient or persistent setting.

TIP: In Elastic Cloud, use the user settings feature to configure all cluster settings. This method automatically rejects unsafe settings that could break your cluster. If you run Elasticsearch on your own hardware, use this API to configure dynamic cluster settings. Only use elasticsearch.yml for static cluster settings and node settings. The API doesn’t require a restart and ensures a setting’s value is the same on all nodes.

WARNING: Transient cluster settings are no longer recommended. Use persistent cluster settings instead. If a cluster becomes unstable, transient settings can clear unexpectedly, resulting in a potentially undesired cluster configuration.

Get the cluster health status Generally available; Added in 1.3.0

GET /_cluster/health/{index}

All methods and paths for this operation:

GET /_cluster/health

GET /_cluster/health/{index}

You can also use the API to get the health status of only specified data streams and indices. For data streams, the API retrieves the health status of the stream’s backing indices.

The cluster health status is: green, yellow or red. On the shard level, a red status indicates that the specific shard is not allocated in the cluster. Yellow means that the primary shard is allocated but replicas are not. Green means that all shards are allocated. The index level status is controlled by the worst shard status.

One of the main benefits of the API is the ability to wait until the cluster reaches a certain high watermark health level. The cluster status is controlled by the worst index status.

Required authorization

  • Cluster privileges: monitor,manage

Path parameters

  • index string | array[string] Required

    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 *.

Get the pending cluster tasks Generally available

GET /_cluster/pending_tasks

Get information about cluster-level changes (such as create index, update mapping, allocate or fail shard) that have not yet taken effect.

NOTE: This API returns a list of any pending updates to the cluster state. These are distinct from the tasks reported by the task management API which include periodic tasks and tasks initiated by the user, such as node stats, search queries, or create index requests. However, if a user-initiated task such as a create index command causes a cluster state update, the activity of this task might be reported by both task api and pending cluster tasks API.

Required authorization

  • Cluster privileges: monitor

Query parameters

  • local boolean

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

  • master_timeout string

    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.

    Values are -1 or 0.

Get remote cluster information Generally available; Added in 6.1.0

GET /_remote/info

Get information about configured remote clusters. The API returns connection and endpoint information keyed by the configured remote cluster alias.


This API returns information that reflects current state on the local cluster. The connected field does not necessarily reflect whether a remote cluster is down or unavailable, only whether there is currently an open connection to it. Elasticsearch does not spontaneously try to reconnect to a disconnected remote cluster. To trigger a reconnection, attempt a cross-cluster search, ES|QL cross-cluster search, or try the resolve cluster endpoint.

Get the cluster state Generally available; Added in 1.3.0

GET /_cluster/state/{metric}/{index}

All methods and paths for this operation:

GET /_cluster/state

GET /_cluster/state/{metric}
GET /_cluster/state/{metric}/{index}

Get comprehensive information about the state of the cluster.

The cluster state is an internal data structure which keeps track of a variety of information needed by every node, including the identity and attributes of the other nodes in the cluster; cluster-wide settings; index metadata, including the mapping and settings for each index; the location and status of every shard copy in the cluster.

The elected master node ensures that every node in the cluster has a copy of the same cluster state. This API lets you retrieve a representation of this internal state for debugging or diagnostic purposes. You may need to consult the Elasticsearch source code to determine the precise meaning of the response.

By default the API will route requests to the elected master node since this node is the authoritative source of cluster states. You can also retrieve the cluster state held on the node handling the API request by adding the ?local=true query parameter.

Elasticsearch may need to expend significant effort to compute a response to this API in larger clusters, and the response may comprise a very large quantity of data. If you use this API repeatedly, your cluster may become unstable.

WARNING: The response is a representation of an internal data structure. Its format is not subject to the same compatibility guarantees as other more stable APIs and may change from version to version. Do not query this API using external monitoring tools. Instead, obtain the information you require using other more stable cluster APIs.

Claim a connector sync job Technical preview

PUT /_connector/_sync_job/{connector_sync_job_id}/_claim

This action updates the job status to in_progress and sets the last_seen and started_at timestamps to the current time. Additionally, it can set the sync_cursor property for the sync job.

This API is not intended for direct connector management by users. It supports the implementation of services that utilize the connector protocol to communicate with Elasticsearch.

To sync data using self-managed connectors, you need to deploy the Elastic connector service on your own infrastructure. This service runs automatically on Elastic Cloud for Elastic managed connectors.

Path parameters

  • connector_sync_job_id string Required

    The unique identifier of the connector sync job.

application/json

Body Required

  • sync_cursor object

    The cursor object from the last incremental sync job. This should reference the sync_cursor field in the connector state for which the job runs.

  • worker_hostname string Required

    The host name of the current system that will run the job.
