# List Federation Issuers

`organization.federation.issuers.list(**kwargs) -> PageCursor<FederationIssuer>`

**GET** `/v1/organizations/federation_issuers`

**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=ruby).

List federation issuers in your organization.

Archived issuers are excluded unless `include_archived=true`.

## Parameters

- `include_archived: bool` (query parameter)

  Include archived resources. Defaults to false.

- `limit: Integer` (query parameter)

  Number of results per page.

  minimum: 1, maximum: 100

- `page: String` (query parameter)

  Opaque cursor from a previous response's `next_page`.

## Returns

- `class FederationIssuer`

  Registered external OIDC identity provider.

  Records an external IdP the organization trusts for the RFC 7523
  jwt-bearer grant. The `issuer_url` must match the JWT `iss` claim exactly.

  - `type: :federation_issuer`

  - `id: String`

    Tagged ID of the federation issuer.

  - `archived_at: Time`

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

    format: date-time

  - `archived_by_actor_id: String`

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

  - `check_jti: bool`

    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.

  - `created_at: Time`

    When this issuer was created.

    format: date-time

  - `created_by_actor_id: String`

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

  - `issuer_url: String`

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

  - `jwks: JWKSDiscovery | JWKSExplicitURL | JWKSInline`

    How signing keys are obtained for signature verification.

    - `class JWKSDiscovery`

      JWKS via the issuer's OIDC discovery document.

      - `type: :discovery`

      - `ca_cert_pem: String`

        Optional custom CA (PEM) for TLS verification of the JWKS fetch.

        maxLength: 8192

      - `discovery_base: String`

        Set when the discovery URL differs from `issuer_url`.

    - `class JWKSExplicitURL`

      JWKS fetched from a fixed endpoint.

      - `type: :explicit_url`

      - `url: String`

        JWKS endpoint.

        minLength: 1

      - `ca_cert_pem: String`

        Optional custom CA (PEM) for TLS verification of the JWKS fetch.

        maxLength: 8192

    - `class JWKSInline`

      JWKS supplied directly; no network fetch.

      - `type: :inline`

      - `keys: Array[Hash[Symbol, untyped]]`

        Inline JWK objects.

        minItems: 1

  - `jwks_polling_disabled_at: Time`

    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.

    format: date-time

  - `max_jwt_lifetime_seconds: Integer`

    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.

  - `name: String`

    Admin-chosen slug identifier.

  - `poll_status: FederationIssuerPollStatus`

    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.

    - `consecutive_failures: Integer`

      Consecutive fetch failures since the last success.

    - `last_fetched_at: Time`

      When the last successful fetch completed.

      format: date-time

    - `next_poll_at: Time`

      When the next fetch is scheduled. Null if paused.

      format: date-time

  - `updated_at: Time`

    When this issuer was last updated.

    format: date-time

  - `updated_by_actor_id: String`

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

## Example

```ruby
require "anthropic"

anthropic = Anthropic::Client.new(api_key: "my-anthropic-api-key")
