## Update

`client.policyBundle.update("string" | "ArrayBuffer" | "ArrayBufferView" | 2 morebody, PolicyBundleUpdateParamsparams, RequestOptionsoptions?): Response`

**put** `/policy/bundle`

Accepts an edited Policy Bundle archive and applies it as the active
user-scope PolicySetVersion for the calling user.

The user's policy set is seeded from the system-default policies on
first access, forked into customer-owned policies; a user bundle
therefore contains only customer-owned policies. Applying an edit
creates a new version of the affected policy, and a `new_policy` entry
adds a further customer-owned policy. Platform-owned catalog policies
are never edited in place by this operation.

The request body codec is determined from `Content-Type`. The only codec
supported today is `application/vnd.keycard.policy-bundle.v1+tar+gzip`.

Supports optimistic concurrency via `If-Match`: when supplied, the server
applies the bundle only if the supplied ETag matches the current bundle
ETag; otherwise responds `412 Precondition Failed`.

On success the server returns the materialized bundle (in the same
codec) and its new `ETag`.

### Parameters

- `body: "string" | "ArrayBuffer" | "ArrayBufferView" | 2 more`

  tar+gzip Policy Bundle archive. `manifest.json` is **required**
  (see `PolicyBundleManifest`); `schema.cedarschema` is **optional
  and ignored** — the server validates against its attested schema
  for `manifest.schema.version`. The manifest's `policies[]` list is
  authoritative for the resulting set: each entry must have a
  matching `policies/<public_id>.cedar` (or, for a `new_policy`
  entry, `policies/<new_policy>.cedar`) member, and a member with no
  manifest entry is dropped. Only the `sha` fields are advisory and
  recomputed server-side. Duplicate or unrecognized entries are
  rejected with `bundle_invalid`. See the **PolicyBundle** tag for
  the layout.

- `params: PolicyBundleUpdateParams`

  - `ifMatch?: string`

    Header param: Optimistic concurrency ETag. When supplied, the server applies the
    bundle only if the value matches the current bundle ETag; otherwise
    responds `412 Precondition Failed`.

  - `xClientRequestID?: string`

    Header param: Unique request identifier specified by the originating caller and passed along by proxies.

### Returns

- `unnamed_schema_1 = Response`

### Example

```typescript
import KeycardAPI from '@keycardai/api';

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

const policyBundle = await client.policyBundle.update(fs.createReadStream('path/to/file'));

console.log(policyBundle);

const content = await policyBundle.blob();
console.log(content);
```
