# Create Federation Issuer

`organization.federation.issuers.create(**kwargs)  -> FederationIssuer`

**POST** `/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=python).

Register an OIDC issuer that Anthropic will trust for workload identity
federation in your organization.

The `jwks` field controls how the issuer's signing keys are obtained and
takes one of three shapes selected by `type`: `discovery` (resolve keys
through OIDC discovery), `explicit_url` (fetch keys from a fixed JWKS
URL), or `inline` (provide a static key set). When `jwks.type` is
`discovery` and no `discovery_base` is set, the issuer URL must be
publicly reachable over HTTPS so Anthropic can fetch the discovery
document; for `explicit_url` and `inline` modes the issuer URL is only
matched as the JWT's `iss` claim and is not fetched.

## Parameters

- `issuer_url: str`

  The `iss` claim value to match against.

  minLength: 1

- `name: str`

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

  minLength: 1, maxLength: 255

- `check_jti: Optional[bool]`

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

- `jwks: Optional[JWKS]`

  How signing keys are obtained. Defaults to OIDC discovery.

  - `class JWKSDiscovery`

    JWKS via the issuer's OIDC discovery document.

    - `type: Literal["discovery"]`

    - `ca_cert_pem: Optional[str]`

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

      maxLength: 8192

    - `discovery_base: Optional[str]`

      Set when the discovery URL differs from `issuer_url`.

  - `class JWKSExplicitURL`

    JWKS fetched from a fixed endpoint.

    - `type: Literal["explicit_url"]`

    - `url: str`

      JWKS endpoint.

      minLength: 1

    - `ca_cert_pem: Optional[str]`

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

      maxLength: 8192

  - `class JWKSInline`

    JWKS supplied directly; no network fetch.

    - `type: Literal["inline"]`

    - `keys: List[Dict[str, object]]`

      Inline JWK objects.

      minItems: 1

- `max_jwt_lifetime_seconds: Optional[int]`

  Maximum allowed iat→exp spread for assertions from this issuer (1-176400 seconds, i.e. up to 49h). Defaults to 3600 (1h). Assertions must carry both `iat` and `exp`; a missing `iat` is rejected.

  minimum: 1, maximum: 176400

## 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: Literal["federation_issuer"]`

    default: federation_issuer

  - `id: str`

    Tagged ID of the federation issuer.

  - `archived_at: Optional[datetime]`

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

    format: date-time

  - `archived_by_actor_id: Optional[str]`

    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: datetime`

    When this issuer was created.

    format: date-time

  - `created_by_actor_id: Optional[str]`

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

  - `issuer_url: str`

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

  - `jwks: JWKS`

    How signing keys are obtained for signature verification.

    - `class JWKSDiscovery`

      JWKS via the issuer's OIDC discovery document.

      - `type: Literal["discovery"]`

      - `ca_cert_pem: Optional[str]`

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

        maxLength: 8192

      - `discovery_base: Optional[str]`

        Set when the discovery URL differs from `issuer_url`.

    - `class JWKSExplicitURL`

      JWKS fetched from a fixed endpoint.

      - `type: Literal["explicit_url"]`

      - `url: str`

        JWKS endpoint.

        minLength: 1

      - `ca_cert_pem: Optional[str]`

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

        maxLength: 8192

    - `class JWKSInline`

      JWKS supplied directly; no network fetch.

      - `type: Literal["inline"]`

      - `keys: List[Dict[str, object]]`

        Inline JWK objects.

        minItems: 1

  - `jwks_polling_disabled_at: Optional[datetime]`

    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: int`

    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: str`

    Admin-chosen slug identifier.

  - `poll_status: Optional[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: int`

      Consecutive fetch failures since the last success.

    - `last_fetched_at: Optional[datetime]`

      When the last successful fetch completed.

      format: date-time

    - `next_poll_at: Optional[datetime]`

      When the next fetch is scheduled. Null if paused.

      format: date-time

  - `updated_at: datetime`

    When this issuer was last updated.

    format: date-time

  - `updated_by_actor_id: Optional[str]`

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

## Example

```python
import os
from anthropic import Anthropic

client = Anthropic(
    api_key=os.environ.get(
        "ANTHROPIC_API_KEY"
    ),  # This is the default and can be omitted
)
federation_issuer = client.organization.federation.issuers.create(
    issuer_url="x",
    name="x",
)
print(federation_issuer.id)
