## Add Federation Rule Workspace

**post** `/v1/organizations/federation_rules/{federation_rule_id}/workspaces`

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. Admin API keys are not accepted.

### Path Parameters

- `federation_rule_id: string`

  ID of the federation rule.

### Header Parameters

- `"anthropic-beta": optional array of string`

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

  To use multiple betas, use a comma separated list like `beta1,beta2` or specify the header multiple times for each beta.

### Body Parameters

- `workspace_id: string`

  Tagged ID of the workspace to enable this rule for.

### Returns

- `created_at: string`

  When this workspace was enabled for the rule.

- `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.

- `type: "federation_rule_workspace"`

  - `"federation_rule_workspace"`

- `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.
