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


















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 CAT help Generally available

GET /_cat

Get help for the CAT APIs.

Get data frame analytics jobs Generally available; Added in 7.7.0

All methods and paths for this operation:

GET /_cat/ml/data_frame/analytics

GET /_cat/ml/data_frame/analytics/{id}

Get pending task information Generally available

GET /_cat/pending_tasks

Get information about cluster-level changes that have not yet taken effect. 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 pending cluster tasks API.

Required authorization

  • Cluster privileges: monitor

Query parameters

  • 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.

  • 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.

  • master_timeout string
