# List Federation Rule Workspaces

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

**GET** `/v1/organizations/federation_rules/{federation_rule_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 workspaces where this federation rule is enabled.

Returns all workspace enablements in a single response; the `limit` and
`page` parameters are accepted but have no effect, and `next_page` is
always `null`. Returns explicit per-workspace enablements only; for
rules with `applies_to_all_workspaces` or a legacy single
`workspace_id`, check those fields on the rule itself.

## Parameters

- `WorkspaceListParams parameters`

  - `required string federationRuleID` (path parameter)

    ID of the federation rule.

  - `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 FederationRuleWorkspace`

  - `JsonElement Type = "federation_rule_workspace"`

  - `required DateTimeOffset CreatedAt`

    When this workspace was enabled for the rule.

    format: date-time

  - `required string? CreatedByActorID`

    Tagged ID (`user_...` or `svac_...`) of the actor that enabled this workspace for the rule, if known.

  - `required string FederationRuleID`

    Tagged ID of the federation rule.

  - `required string WorkspaceID`

    Tagged ID of the workspace this rule is enabled for.

  - `required string? WorkspaceName`

    Workspace display name. Populated when listing; null in the enable response.

## Example

```csharp
using System;
using Anthropic.Models.Organization.Federation.Rules.Workspaces;

WorkspaceListParams parameters = new()
{
    FederationRuleID = "federation_rule_id"
};

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