## Create a Namespace

`client.kv.namespaces.create(NamespaceCreateParamsparams, RequestOptionsoptions?): Namespace`

**post** `/accounts/{account_id}/storage/kv/namespaces`

Creates a namespace under the given title. A `400` is returned if the account already owns a namespace with this title. A namespace must be explicitly deleted to be replaced.

### Parameters

- `params: NamespaceCreateParams`

  - `account_id: string`

    Path param: Identifier.

  - `title: string`

    Body param: A human-readable string name for a Namespace.

### Returns

- `Namespace`

  - `id: string`

    Namespace identifier tag.

  - `title: string`

    A human-readable string name for a Namespace.

  - `supports_url_encoding?: boolean`

    True if keys written on the URL will be URL-decoded before storing. For example, if set to "true", a key written on the URL as "%3F" will be stored as "?".

### Example

```node
import Cloudflare from 'cloudflare';

const client = new Cloudflare({
  apiToken: process.env['CLOUDFLARE_API_TOKEN'], // This is the default and can be omitted
});

const namespace = await client.kv.namespaces.create({
  account_id: '023e105f4ecef8ad9ca31a8372d0c353',
