# Delete data streams

Availability: Generally available since 7.9

## Paths

- `DELETE` `/_data_stream/{name}`

#### Path parameters

- `name` (union string | string[]) — required
  Comma-separated list of data streams to delete. Wildcard (`*`) expressions are supported.

## Description

Deletes one or more data streams and their backing indices.

## Required authorization

- Index privileges: `delete_index`

## 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](https://www.elastic.co/docs/deploy-manage/users-roles/cluster-or-deployment-auth/token-based-authentication-services)

## Query string parameters

- `master_timeout` (string · default: 30s) — optional
  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.
- `expand_wildcards` (string · default: open) — optional
  Type of data stream that wildcard patterns can match. 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`

## Response

`application/json`

- `acknowledged` (boolean)
  For a successful response, this value is always true. On failure, an exception is returned instead.
