# Duplicate rule

> Create a copy of an existing rule.

Creates a copy of one existing rule.

## Headers

<ParamField header="Authorization" type="string" required>
  Bearer token containing your Fini workspace API key. Format: `Bearer fini_...` The key needs `write` scope.
</ParamField>

<ParamField header="Content-Type" type="string" required>
  `application/json`
</ParamField>

## Path parameters

<ParamField path="id" type="string" required>
  Rule ID to duplicate.
</ParamField>

## Body parameters

<ParamField body="name" type="string">
  Optional name override for the duplicated rule.
</ParamField>

<ParamField body="description" type="string">
  Optional description override for the duplicated rule.
</ParamField>

## Response

Returns the duplicated [`Rule`](/en/api-reference/rules#rule-object).

<Note>
  Current controller behavior:

  * Duplicating an `intent` rule creates a **draft** copy.
  * Duplicating a `business` rule creates a non-draft copy.
  * The duplicate response is returned directly from storage, so `botIds` are not expanded. Call [Get rule](/en/api-reference/get-rule) if you need the enriched read shape.
</Note>
