# List Federation Rule Workspaces

**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=http).

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.

## Path parameters

- `federation_rule_id: string`

  ID of the federation rule.

## Query parameters

- `limit: optional number`

  Number of results per page.

  default: 20, minimum: 1, maximum: 100

- `page: optional string`

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

## Headers

- `"anthropic-version": optional string`

  The version of the Claude API you want to use.

## Returns

- `data: array of FederationRuleWorkspace`

  - `type: "federation_rule_workspace"`

    default: federation_rule_workspace

  - `created_at: string`

    When this workspace was enabled for the rule.

    format: date-time

  - `created_by_actor_id: string or null`

    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 or null`

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

- `next_page: string or null`

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

```bash
curl https://api.anthropic.com/v1/organizations/federation_rules/$FEDERATION_RULE_ID/workspaces \
