# List Workspaces For Service Account

`WorkspaceListPage Organization.ServiceAccounts.Workspaces.List(parameters, cancellationToken = default)`

**GET** `/v1/organizations/service_accounts/{service_account_id}/workspaces`

**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=csharp).

List the workspaces a service account is a member of.

Each entry includes the service account's `workspace_role` in that
workspace. Use `limit` and the `next_page` cursor to paginate. When the
service account has no explicit default-workspace membership, the
implicit (`implicit: true`) membership is returned as the first entry on
the first page; with `limit=1` the first page may return up to 2 entries
(the implicit entry plus one explicit membership) so a pagination cursor
can be derived. Memberships are returned only while
the service account is active. Without a `page` cursor, an archived
service account returns an empty list. A `page` cursor that does not
match an active membership returns a 400 invalid-request error. A cursor
stops matching when the membership is removed, the workspace is deleted,
or the service account is archived. Restart pagination from the first
page to recover.

## Parameters

- `WorkspaceListParams parameters`

  - `required string serviceAccountID` (path parameter)

    ID of the service account.

  - `long limit` (query parameter)

    Number of results per page.

    minimum: 1, maximum: 100

  - `string? page` (query parameter)

    Opaque cursor from a previous response's `next_page`.

## Returns

- `class ServiceAccountWorkspaceMember`

  - `JsonElement Type = "service_account_workspace_member"`

  - `required string? CreatedByActorID`

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

  - `required 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.

  - `required string ServiceAccountID`

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

  - `required string WorkspaceID`

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

  - `required WorkspaceRole WorkspaceRole`

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

    - `WorkspaceAdmin("workspace_admin")`

    - `WorkspaceBilling("workspace_billing")`

    - `WorkspaceDeveloper("workspace_developer")`

    - `WorkspaceRestrictedDeveloper("workspace_restricted_developer")`

    - `WorkspaceUser("workspace_user")`

## Example

```csharp
using System;
using Anthropic.Models.Organization.ServiceAccounts.Workspaces;

WorkspaceListParams parameters = new()
{
    ServiceAccountID = "service_account_id"
};

var page = await client.Organization.ServiceAccounts.Workspaces.List(parameters);
await foreach (var item in page.Paginate())
{
    Console.WriteLine(item);
}
```
