# Reset a transform

Availability: 8.1+

## Paths

- `POST` `/_transform/{transform_id}/_reset`

- [Api key auth](/elastic/docs-builder/docs/4371/api/doc/elasticsearch/authentication#apikeyauth)
- [Basic auth](/elastic/docs-builder/docs/4371/api/doc/elasticsearch/authentication#basicauth)
- [Bearer auth](/elastic/docs-builder/docs/4371/api/doc/elasticsearch/authentication#bearerauth)

#### Path Parameters

- `transform_id` (string Id)
  Identifier for the transform. This identifier can contain lowercase alphanumeric characters (a-z and 0-9),
hyphens, and underscores. It has a 64 character limit and must start and end with alphanumeric characters.

## Description

Before you can reset it, you must stop it; alternatively, use the `force` query parameter.
If the destination index was created by the transform, it is deleted.

## Required authorization

* Cluster privileges: `manage_transform`

## Query String Parameters

- `force` (boolean · default: false)
  If this value is `true`, the transform is reset regardless of its current state. If it's `false`, the transform
must be stopped before it can be reset.
- `timeout` (string Duration · default: 30s)
  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.
