# List Federation Rule Workspaces

`$ ant beta:organization:federation:rules:workspaces list`

**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=cli).

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: optional number` (query parameter)

  Number of results per page.

  minimum: 1, maximum: 100

- `--page: optional string` (query parameter)

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

- `--beta: optional array of AnthropicBeta` (header parameter)

  Optional header to specify the beta version(s) you want to use.

## Returns

- `BetaFederationRuleWorkspaceListResponse: object`

  - `data: array of BetaFederationRuleWorkspace`

    - `type: "federation_rule_workspace"`

    - `created_at: string`

      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.

  - `next_page: string`

    Opaque cursor for the next page; null when there are no more results.

## Example

```bash
ant beta:organization:federation:rules:workspaces list \
  --api-key my-anthropic-api-key \
  --federation-rule-id federation_rule_id
