# Update

> This command updates the tag filters for the contract. To update other aspects of the contract graph please use the federated-graph or monograph update commands.

## Usage

#### Exclude (the items that have the tag(s) specified will be removed from the source federated graph)

```bash theme={null}
npx wgc contract update <name> --source <contract-name> --exclude internal
```

#### Include (the items that have the tag(s) specified will be included in the source federated graph)

```bash theme={null}
npx wgc contract update <name> --source <contract-name> --include public
```

## Description

The `npx wgc contract update` command allows you to update the tag filters for the contract. This will result in overwriting existing ones and causes a recomposition of the contract graph.

## Parameters

* `<name>`: The name of the contract graph you want to update.

## Options

<Note>
  The --exclude and --include options are currently *mutually exclusive*. An error will be returned if more than one are defined. The undefined option will be automatically unset.
</Note>

* `-n, --namespace` : The namespace of the federated graph (Default: "default").
* `--exclude` : The list of tags that should be excluded from the source graph schema.
* `--include` : The list of tags that should be included from the source graph schema.
* `-r , --routing-url`: The routing URL of your router. This URL defines the endpoint where the router will be accessible. The contract graph will be accessible through this router.
* `--admission-webhook-url <url>` the base url of the admission webhook. This is the url that the controlplane will use to implement admission control for the contract graph. Example: `https://admission.example.com` (without the `/validate-config` path name)
* `--admission-webhook-secret`: Allows you to sign requests (HMAC) made to your admission webhook url. The header containing this signature is `X-Cosmo-Signature-256`
* `--readme` : The markdown file which describes the contract graph.
* `--suppress-warnings`: This flag suppresses any warnings produced by composition.
