# Create Federation Rule

`$client->organization->federation->rules->create(string issuerID, FederationRuleMatch match, string name, string oauthScope, ServiceAccountTarget target, ?bool appliesToAllWorkspaces, ?string description, ?int tokenLifetimeSeconds, ?string workspaceID): FederationRule`

**POST** `/v1/organizations/federation_rules`

**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=php).

Create a federation rule owned by your organization.

The referenced issuer and the target service account must already exist
in the same organization; invalid references are rejected with a 400
error. The workspace reference is validated. Membership is not checked
at rule creation: token exchange resolves a single enabled workspace per
call and is rejected unless the target service account is a member of
that workspace (it is implicitly a member of the default workspace).
Rules on well-known shared issuers (GitHub Actions, GitLab, Buildkite,
Terraform Cloud, Google) must constrain tenant identity via an
identity-bearing claim, a tenant-pinning subject prefix (such as
`repo:YOUR_ORG/...`), or a CEL condition referencing one of those
identity claims (e.g. `claims.repository_owner`). OAuth callers may only
manage rules whose `oauth_scope` is `workspace:developer` or
`workspace:inference`; other scopes require a Console session.

## Parameters

- `issuerID: string`

  Tagged ID of the federation issuer.

- `match: FederationRuleMatch`

  Conditions the verified JWT must satisfy for this rule to apply. At least one of `subject_prefix` (other than a wildcard-only value like `*`), `claims`, or `condition` is required; `audience` alone is not sufficient.

- `name: string`

  Slug identifier (lowercase, digits, hyphens). Unique within the organization; a duplicate name returns 409.

- `oauthScope: string`

  Space-separated OAuth scopes. OAuth callers may only set `workspace:developer` or `workspace:inference`; other scopes (such as `org:admin`) require a Console session.

- `target: ServiceAccountTarget`

  Identity that tokens minted via this rule act as. Currently always a `service_account` target.

- `appliesToAllWorkspaces?:optional bool`

  When true, enable this rule for every workspace in the org (including workspaces created later).

- `description?:optional string`

  Optional free-text description.

- `tokenLifetimeSeconds?:optional int`

  Lifetime in seconds for access tokens minted via this rule (60-86400). Defaults to 3600 (1h). Minted tokens are capped at `max(60, min(this value, 2 × remaining assertion validity))` seconds.

- `workspaceID?:optional string`

  Tagged ID of the workspace to enable this rule for. Required unless `applies_to_all_workspaces` is true. Additional workspaces can be added via the `/federation_rules/{federation_rule_id}/workspaces` sub-resource.

## Returns

- `class FederationRule`

  - `"federation_rule" type`

  - `string id`

    Tagged ID of the federation rule.

  - `bool appliesToAllWorkspaces`

    When true, this rule is enabled for every workspace in the org (including ones created after the rule). `workspace_ids` is ignored at exchange time.

  - `?\Datetime archivedAt`

    If set, this rule is archived and rejects token exchange.

  - `?string archivedByActorID`

    Tagged ID (`user_`/`svac_`) of the actor that archived this rule.

  - `\Datetime createdAt`

    When this rule was created.

  - `?string createdByActorID`

    Tagged ID (`user_`/`svac_`) of the actor that created this rule.

  - `?string description`

    Optional free-text description.

  - `string issuerID`

    Tagged ID of the issuer whose tokens this rule accepts.

  - `?string issuerName`

    Issuer's display name at read time.

  - `FederationRuleMatch match`

    Conditions the verified JWT must satisfy for this rule to apply. All populated matcher fields must pass.

  - `string name`

    Admin-chosen slug identifier.

  - `string oauthScope`

    Space-separated OAuth scopes granted on the minted token.

  - `ServiceAccountTarget target`

    What this rule targets. Check `type` before reading the other fields. Tokens minted via a rule whose target `type` is `service_account` act as that service account.

  - `int tokenLifetimeSeconds`

    Lifetime in seconds of access tokens minted via this rule. Minted tokens are capped at `max(60, min(this value, 2 × remaining assertion validity))` seconds.

  - `\Datetime updatedAt`

    When this rule was last updated.

  - `?string updatedByActorID`

    Tagged ID (`user_`/`svac_`) of the actor that last updated this rule.

  - `list<string> workspaceIDs`

    Tagged IDs of the workspaces this rule is enabled for. May be empty for older rules that only carry the legacy `workspace_id` binding. Ignored at exchange time when `applies_to_all_workspaces` is true (the list may still be non-empty).

## Example

```php
<?php

require_once dirname(__DIR__) . '/vendor/autoload.php';

use Anthropic\Client;

$client = new Client(apiKey: 'my-anthropic-api-key');

$federationRule = $client->organization->federation->rules->create(
  issuerID: 'issuer_id',
  match: [
    'audience' => 'audience',
    'claims' => ['foo' => 'string'],
    'condition' => 'condition',
    'subjectPrefix' => 'subject_prefix',
  ],
  name: 'x',
  oauthScope: 'x',
  target: [
    'serviceAccountID' => 'svac_01SDCCSbTxrXDpWc1phhtcfK',
    'type' => 'service_account',
    'serviceAccountName' => 'service_account_name',
  ],
  appliesToAllWorkspaces: true,
  description: 'description',
  tokenLifetimeSeconds: 60,
  workspaceID: 'workspace_id',
);

var_dump($federationRule);
```
