# Get Federation Issuer

`$client->organization->federation->issuers->retrieve(string federationIssuerID): FederationIssuer`

**GET** `/v1/organizations/federation_issuers/{federation_issuer_id}`

**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).

Retrieve a federation issuer by its ID (`fdis_...`).

## Parameters

- `federationIssuerID: string` (path parameter)

  ID of the federation issuer.

## Returns

- `class FederationIssuer`

  - `"federation_issuer" type`

  - `string id`

    Tagged ID of the federation issuer.

  - `?\Datetime archivedAt`

    If set, all rules referencing this issuer reject token exchange.

  - `?string archivedByActorID`

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

  - `bool checkJTI`

    Whether the jwt-bearer exchange enforces JTI single-use (replay protection) for tokens from this issuer. Applies only to assertions carrying a `jti` claim; tokens without one are accepted without single-use enforcement.

  - `\Datetime createdAt`

    When this issuer was created.

  - `?string createdByActorID`

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

  - `string issuerURL`

    The `iss` claim value. Incoming JWTs must match exactly.

  - `JWKS jwks`

    How signing keys are obtained for signature verification.

  - `?\Datetime jwksPollingDisabledAt`

    If set, Anthropic's JWKS poller has paused polling for this issuer after repeated fetch failures. Re-enable by sending `jwks_polling_disabled: false` via the issuer update endpoint (POST) once the upstream JWKS endpoint is fixed. An OAuth caller cannot send this when the issuer backs a rule with any scope other than `workspace:developer` or `workspace:inference`; use a Console session.

  - `int maxJWTLifetimeSeconds`

    Maximum allowed iat→exp spread for assertions from this issuer (1-176400 seconds, i.e. up to 49h). Assertions must carry both `iat` and `exp`; a missing `iat` is rejected.

  - `string name`

    Admin-chosen slug identifier.

  - `?FederationIssuerPollStatus pollStatus`

    Live state of Anthropic's JWKS polling for this issuer. Populated on both single-issuer retrieval and list responses, including archived issuers. Typically null for inline-key issuers (no polling), or when poll status is temporarily unavailable or polling has not started yet.

  - `\Datetime updatedAt`

    When this issuer was last updated.

  - `?string updatedByActorID`

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

## Example

```php
<?php

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

use Anthropic\Client;

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

$federationIssuer = $client->organization->federation->issuers->retrieve(
  'federation_issuer_id'
);

var_dump($federationIssuer);
```
