# Create a data stream

Availability: Generally available since 7.9

## Paths

- `PUT` `/_data_stream/{name}`

#### Path parameters

- `name` (string) — required
  Name of the data stream, which must meet the following criteria:
Lowercase only;
Cannot include `\`, `/`, `*`, `?`, `"`, `<`, `>`, `|`, `,`, `#`, `:`, or a space character;
Cannot start with `-`, `_`, `+`, or `.ds-`;
Cannot be `.` or `..`;
Cannot be longer than 255 bytes. Multi-byte characters count towards this limit faster.

## Description

You must have a matching index template with data stream enabled.

## Required authorization

- Index privileges: `create_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/guide/en/elasticsearch/reference/current/token-authentication-services.html)

## 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.
- `timeout` (string · default: 30s) — optional
  Period to wait for a response. If no response is received before the timeout expires, the request fails and returns an error.

## Response

`application/json`

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