title: Use WIF with Okta
url: https://platform.claude.com/docs/en/manage-claude/wif-providers/okta
description: Federate Okta service application identities to the Claude API with Workload Identity Federation.
---

Okta can act as a workload identity provider by issuing OIDC access tokens to a **service application** through the OAuth 2.0 `client_credentials` grant. Your workload authenticates to Okta (typically with `private_key_jwt`, so no shared secret is stored), receives a signed JSON Web Token (JWT), and exchanges that JWT with Anthropic for a short-lived access token.

The Okta authorization server's issuer URL takes the form `https://<your-domain>.okta.com/oauth2/<auth-server-id>`. If you use the built-in default server, the path is `/oauth2/default`.

<Note>
  You must use an Okta **custom authorization server** (including the `default` one). Tokens issued directly by the Okta org authorization server (the `/oauth2/v1/token` endpoint with no authorization server ID in the path) cannot be validated by external parties because Okta does not publish signing keys for them.
</Note>

There are many ways to configure and authenticate to Okta that are outside the scope of this documentation. Ensure that your configuration and authentication mechanisms follow your company's guidance and security practices.

## Prerequisites

* Familiarity with [WIF concepts](https://platform.claude.com/docs/en/manage-claude/workload-identity-federation#concepts): service accounts, federation issuers, and federation rules.
* An Okta organization with API Access Management enabled (required for custom authorization servers).
* Permission to create service accounts, federation issuers, and federation rules in the Claude Console for your Anthropic organization.
* A workload that can request a token from Okta's `/v1/token` endpoint and reach `api.anthropic.com`.

## Configure Okta

At a high level you need to:

1. Create an Okta service application.
2. Configure your default authorization server (or create a new custom authorization server) with an audience, a scope, an access policy, and any custom claims you want to match on.

The exact navigation depends on your Okta org configuration and admin console version. The following numbered steps walk through one common path:

1. **Create a service app integration.** In the Okta Admin Console, create a new app integration of type **API Services** (OIDC, machine-to-machine). Note the generated **Client ID**.
2. **Configure client authentication.** For a keyless setup, choose **Public key / Private key** (`private_key_jwt`) and register your workload's public JWK. Alternatively, use a client secret if your environment can store one securely. For the following example you may need to disable the DPoP requirement on the application; ensure that your production setup adheres to your organization's security requirements.
3. **Set the audience.** On your custom authorization server, set the audience to `https://api.anthropic.com` so issued access tokens carry that `aud` claim. Anthropic validates `aud` against this fixed value.
4. **Grant a scope.** On your custom authorization server, ensure at least one scope exists that the service app is allowed to request (for example, `anthropic.access`). Okta rejects `client_credentials` requests that do not include a granted scope.
5. **Create an access policy.** On your custom authorization server, create an access policy with at least one rule that allows your service app to request the scope you granted in step 4.
6. **(Optional) Add custom claims.** If you want to match on something other than the client ID, add a claim to the access token in your authorization server's **Claims** tab.

For a service app using `client_credentials`, Okta sets the `sub` claim of the issued access token to the application's **Client ID**, and `iss` to the authorization server's issuer URL.

## Configure Anthropic

In the Claude Console, open **Settings → Workload identity**, click **Connect workload**, and select **Custom OIDC**. The wizard walks you through registering the issuer, creating a service account, and creating a federation rule.

The wizard creates these resources for you. Use the following values whether you enter them in the wizard or send them to the [Admin API](https://platform.claude.com/docs/en/manage-claude/wif-admin-api):

**Federation issuer:** Use your Okta custom authorization server URL and discovery mode. Anthropic reads Okta's `.well-known/openid-configuration` discovery document and fetches the JWKS from the `jwks_uri` it advertises.

```json
{
  "name": "okta-prod",
  "issuer_url": "https://acme.okta.com/oauth2/aus1a2b3c4d5e6f7g8h9",
  "jwks": { "type": "discovery" }
}
```

**Federation rule:** Match on the Okta `sub` claim, which is the service app's Client ID. If you defined custom claims in Okta, you can match on those instead with the `claims` map or a CEL `condition`.

```json
{
  "name": "okta-pipeline",
  "issuer_id": "fdis_...",
  "match": {
    "subject_prefix": "0oa1b2c3d4e5f6g7h8i9",
    "audience": "https://api.anthropic.com"
  },
  "target": { "type": "service_account", "service_account_id": "svac_..." },
  "workspace_id": "wrkspc_...",
  "oauth_scope": "workspace:developer",
  "token_lifetime_seconds": 600
}
```

## Acquire a token and call the Claude API

Unlike platform-native providers (AWS, Google Cloud, Kubernetes), which make a token available inside the workload's runtime (through a projected file or local metadata endpoint), Okta does not. Your workload must call Okta's token endpoint to obtain a JWT, then pass that JWT to the Anthropic SDK as the identity token.

<CodeGroup>
  ```bash cURL
  # 1. Request an access token from Okta (client_credentials with private_key_jwt).
  OKTA_JWT=$(curl -sS "https://acme.okta.com/oauth2/aus1a2b3c4d5e6f7g8h9/v1/token" \
    -d grant_type=client_credentials \
    -d scope=anthropic.access \
    -d client_assertion_type=urn:ietf:params:oauth:client-assertion-type:jwt-bearer \
    --data-urlencode client_assertion="$SIGNED_CLIENT_ASSERTION" \
    | jq -r .access_token)

  # 2. Exchange the Okta JWT for an Anthropic access token.
  ACCESS_TOKEN=$(curl -sS https://api.anthropic.com/v1/oauth/token \
    -H "content-type: application/json" \
    -d @- <<JSON | jq -r .access_token
  {
    "grant_type": "urn:ietf:params:oauth:grant-type:jwt-bearer",
    "assertion": "$OKTA_JWT",
    "federation_rule_id": "$ANTHROPIC_FEDERATION_RULE_ID",
    "organization_id": "$ANTHROPIC_ORGANIZATION_ID",
    "service_account_id": "$ANTHROPIC_SERVICE_ACCOUNT_ID",
    "workspace_id": "$ANTHROPIC_WORKSPACE_ID"
  }
  JSON
  )

  # 3. Call the Claude API.
  curl https://api.anthropic.com/v1/messages \
    -H "authorization: Bearer $ACCESS_TOKEN" \
    -H "anthropic-version: 2023-06-01" \
    -H "content-type: application/json" \
    -d '{"model": "claude-opus-5", "max_tokens": 1024, "messages": [{"role": "user", "content": "Hello, Claude"}]}' \
    | jq -r '.content[] | select(.type == "text") | .text'
  ```
