# List Federation Rule Workspaces

`organization.federation.rules.workspaces.list(federation_rule_id, **kwargs) -> PageCursor<FederationRuleWorkspace>`

**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=ruby).

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

- `federation_rule_id: String` (path parameter)

  ID of the federation rule.

- `limit: Integer` (query parameter)

  Number of results per page.

  minimum: 1, maximum: 100

- `page: String` (query parameter)

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

## Returns

- `class FederationRuleWorkspace`

  - `type: :federation_rule_workspace`

  - `created_at: Time`

    When this workspace was enabled for the rule.

    format: date-time

  - `created_by_actor_id: String`

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

  - `federation_rule_id: String`

    Tagged ID of the federation rule.

  - `workspace_id: String`

    Tagged ID of the workspace this rule is enabled for.

  - `workspace_name: String`

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

## Example

```ruby
require "anthropic"

anthropic = Anthropic::Client.new(api_key: "my-anthropic-api-key")

page = anthropic.organization.federation.rules.workspaces.list("federation_rule_id")

puts(page)
```
