# Add Federation Rule Workspace

`organization.federation.rules.workspaces.add(federation_rule_id, **kwargs)  -> FederationRuleWorkspace`

**POST** `/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=python).

Enable a federation rule for a workspace.

Idempotent; re-enabling returns the existing enablement. The rule and
workspace must both belong to your organization. Membership of the
rule's target service account in this workspace is not checked at
enablement: token exchange into this workspace is rejected unless the
target is a member (it is implicitly a member of the default workspace).
Archived rules are rejected with 400. OAuth callers may only manage rules
whose `oauth_scope` is `workspace:developer` or `workspace:inference`;
other scopes require a Console session.

## Parameters

- `federation_rule_id: str` (path parameter)

  ID of the federation rule.

- `workspace_id: str`

  Tagged ID of the workspace to enable this rule for.

## Returns

- `class FederationRuleWorkspace`

  - `type: Literal["federation_rule_workspace"]`

    default: federation_rule_workspace

  - `created_at: datetime`

    When this workspace was enabled for the rule.

    format: date-time

  - `created_by_actor_id: Optional[str]`

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

  - `federation_rule_id: str`

    Tagged ID of the federation rule.

  - `workspace_id: str`

    Tagged ID of the workspace this rule is enabled for.

  - `workspace_name: Optional[str]`

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

## Example

```python
import os
from anthropic import Anthropic

client = Anthropic(
    api_key=os.environ.get(
        "ANTHROPIC_API_KEY"
    ),  # This is the default and can be omitted
)
federation_rule_workspace = client.organization.federation.rules.workspaces.add(
    federation_rule_id="federation_rule_id",
    workspace_id="workspace_id",
)
print(federation_rule_workspace.created_by_actor_id)
```
