# Create Service Account Workspace Member

`$client->organization->workspaces->serviceAccounts->add(string workspaceID, string serviceAccountID, NoBillingWorkspaceRole workspaceRole): ServiceAccountWorkspaceMember`

**POST** `/v1/organizations/workspaces/{workspace_id}/service_accounts`

**Requires an OAuth access token with the `org:admin` scope**, from `ant auth login --scope org:admin` or a workload identity federation rule; Admin API keys are not accepted. See [Manage WIF with the Admin API](https://platform.claude.com/docs/en/manage-claude/wif-admin-api?sdk_languages=php).

Add a service account to a workspace with the given `workspace_role`.

The role determines what the service account can do in the workspace and
which workspace-scoped permissions it can be granted when authenticating
through federation. Every service account is already an implicit
`workspace_user` member of the default workspace; adding it explicitly
assigns a chosen role. If the service account is already an explicit
member of the workspace, its `workspace_role` is replaced with the
value supplied here. Archived workspaces return 400. Archived service
accounts cannot be added and are rejected.

## Parameters

- `workspaceID: string` (path parameter)

  ID of the workspace.

- `serviceAccountID: string`

  Tagged service account ID to add.

- `workspaceRole: NoBillingWorkspaceRole`

  Role to assign to the service account in this workspace.

## Returns

- `class ServiceAccountWorkspaceMember`

  - `"service_account_workspace_member" type`

  - `?string createdByActorID`

    Tagged ID (`user_...`/`svac_...`) of the actor who created this membership.

  - `?bool implicit`

    True when this is the implicit default-workspace membership every service account has when no explicit membership exists. Implicit memberships have role `workspace_user` and cannot be removed.

  - `string serviceAccountID`

    Tagged service account ID (`svac_...`).

  - `string workspaceID`

    Tagged workspace ID (`wrkspc_...`).

  - `WorkspaceRole workspaceRole`

    Role of the service account in this workspace. Service accounts cannot hold the `workspace_billing` role.

## Example

```php
<?php

require_once dirname(__DIR__) . '/vendor/autoload.php';

use Anthropic\Client;
use Anthropic\Organization\Workspaces\NoBillingWorkspaceRole;

$client = new Client(apiKey: 'my-anthropic-api-key');

$serviceAccountWorkspaceMember = $client
  ->organization
  ->workspaces
  ->serviceAccounts
  ->add(
  'workspace_id',
  serviceAccountID: 'service_account_id',
  workspaceRole: NoBillingWorkspaceRole::WORKSPACE_ADMIN,
);

var_dump($serviceAccountWorkspaceMember);
```
