# Reset

The `reset` method allows you to clear all vectors and metadata from a particular
namespace or all namespaces of an index.

## Arguments

There are two arguments available. You should only pass one of them:

<ResponseField name="namespace" type="string">
  Specifies a namespace to reset. Leave empty for the default namespace.
</ResponseField>

<ResponseField name="all" type="true | undefined">
  Whether to reset all namespaces. Can only be set to `true`.
</ResponseField>

## Response

`'Success'` if the index is successfully resetted.
