# Add Federation Rule Workspace

`client.Organization.Federation.Rules.Workspaces.Add(ctx, federationRuleID, body) (*FederationRuleWorkspace, error)`

**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=go).

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

- `federationRuleID string` (path parameter)

  ID of the federation rule.

- `body OrganizationFederationRuleWorkspaceAddParams`

  - `WorkspaceID string`

    Tagged ID of the workspace to enable this rule for.

## Returns

- `type FederationRuleWorkspace`

  - `Type FederationRuleWorkspace`

    default: federation_rule_workspace

  - `CreatedAt Time`

    When this workspace was enabled for the rule.

    format: date-time

  - `CreatedByActorID string`

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

  - `FederationRuleID string`

    Tagged ID of the federation rule.

  - `WorkspaceID string`

    Tagged ID of the workspace this rule is enabled for.

  - `WorkspaceName string`

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

## Example

```go
package main

import (
	"context"

)

func main() {
	client := anthropic.NewClient(
		option.WithAPIKey("my-anthropic-api-key"),
	)
	federationRuleWorkspace, err := client.Organization.Federation.Rules.Workspaces.Add(
		context.TODO(),
		"federation_rule_id",
		anthropic.OrganizationFederationRuleWorkspaceAddParams{
			WorkspaceID: "workspace_id",
		},
	)
	if err != nil {
		panic(err.Error())
	}
	fmt.Printf("%+v\n", federationRuleWorkspace.CreatedByActorID)
}
