# Delete an alias


## Paths

- `DELETE` `/{index}/_aliases/{name}`
- `DELETE` `/{index}/_alias/{name}`

#### Path parameters

- `index` (union string | string[]) — required
  Comma-separated list of data streams or indices used to limit the request.
Supports wildcards (`*`).
- `name` (union string | string[]) — required
  Comma-separated list of aliases to remove.
Supports wildcards (`*`). To remove all aliases, use `*` or `_all`.

## Description

Removes a data stream or index from an alias.

## Required authorization

- Index privileges: `manage`

## 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.
- `timeout` (string · default: 30s) — optional

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