# Check component templates

Availability: Generally available since 7.8

## Paths

- `HEAD` `/_component_template/{name}`

#### Path parameters

- `name` (union string | string[]) — required
  Comma-separated list of component template names used to limit the request.
Wildcard (*) expressions are supported.

## Description

Returns information about whether a particular component template exists.

## 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.
- `local` (boolean · default: false) — optional — deprecated
  If true, the request retrieves information from the local node only.
Defaults to false, which means information is retrieved from the master node.

## Response

`application/json`

## Code examples

```console
HEAD /_component_template/NAME
```

#### curl

curl -X HEAD "${ELASTICSEARCH_URL}/_component_template/${NAME}" \
