# Get Federation Issuer

`client.Organization.Federation.Issuers.Get(ctx, federationIssuerID) (*FederationIssuer, error)`

**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=go).

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

## Parameters

- `federationIssuerID string` (path parameter)

  ID of the federation issuer.

## Returns

- `type 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 FederationIssuer`

    default: federation_issuer

  - `ID string`

    Tagged ID of the federation issuer.

  - `ArchivedAt Time`

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

    format: date-time

  - `ArchivedByActorID string`

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

  - `CheckJTI 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.

  - `CreatedAt Time`

    When this issuer was created.

    format: date-time

  - `CreatedByActorID string`

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

  - `IssuerURL string`

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

  - `JWKS FederationIssuerJWKSUnion`

    How signing keys are obtained for signature verification.

    - `type JWKSDiscovery`

      JWKS via the issuer's OIDC discovery document.

      - `Type Discovery`

      - `CACertPEM string Optional`

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

        maxLength: 8192

      - `DiscoveryBase string Optional`

        Set when the discovery URL differs from `issuer_url`.

    - `type JWKSExplicitURL`

      JWKS fetched from a fixed endpoint.

      - `Type ExplicitURL`

      - `URL string`

        JWKS endpoint.

        minLength: 1

      - `CACertPEM string Optional`

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

        maxLength: 8192

    - `type JWKSInline`

      JWKS supplied directly; no network fetch.

      - `Type Inline`

      - `Keys []map[string, any]`

        Inline JWK objects.

        minItems: 1

  - `JWKSPollingDisabledAt 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

  - `MaxJWTLifetimeSeconds int64`

    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.

  - `PollStatus 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.

    - `ConsecutiveFailures int64`

      Consecutive fetch failures since the last success.

    - `LastFetchedAt Time`

      When the last successful fetch completed.

      format: date-time

    - `NextPollAt Time`

      When the next fetch is scheduled. Null if paused.

      format: date-time

  - `UpdatedAt Time`

    When this issuer was last updated.

    format: date-time

  - `UpdatedByActorID string`

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

## Example

```go
package main

import (
	"context"
	"fmt"

	"github.com/anthropics/anthropic-sdk-go"
	"github.com/anthropics/anthropic-sdk-go/option"
)

func main() {
	client := anthropic.NewClient(
		option.WithAPIKey("my-anthropic-api-key"),
	)
	federationIssuer, err := client.Organization.Federation.Issuers.Get(context.TODO(), "federation_issuer_id")
	if err != nil {
		panic(err.Error())
	}
	fmt.Printf("%+v\n", federationIssuer.ID)
}
```
