# Delete a project routing expression

Availability: Experimental

## Paths

- `DELETE` `/_project_routing/{name}`

#### Path parameters

- `name` (string) — required
  The name of project routing expression

## Required authorization

- Cluster privileges: `manage_project_routing`, `manage`

## Authentication

- Api key: `Authorization: <value>`
  Elasticsearch APIs use 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}"
  ```
  
  For more information about where to find API keys for the Elasticsearch endpoint (${ES_URL}) for a project, go to [Get started with Elasticsearch Serverless](https://www.elastic.co/docs/solutions/search/serverless-elasticsearch-get-started).

## Response

`application/json`

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