# Create Federation Rule

`beta.organization.federation.rules.create(**kwargs) -> BetaFederationRule`

**POST** `/v1/organizations/federation_rules`

**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).

Create a federation rule owned by your organization.

The referenced issuer and the target service account must already exist
in the same organization; invalid references are rejected with a 400
error. The workspace reference is validated. Membership is not checked
at rule creation: token exchange resolves a single enabled workspace per
call and is rejected unless the target service account is a member of
that workspace (it is implicitly a member of the default workspace).
Rules on well-known shared issuers (GitHub Actions, GitLab, Buildkite,
Terraform Cloud, Google) must constrain tenant identity via an
identity-bearing claim, a tenant-pinning subject prefix (such as
`repo:YOUR_ORG/...`), or a CEL condition referencing one of those
identity claims (e.g. `claims.repository_owner`). OAuth callers may only
manage rules whose `oauth_scope` is `workspace:developer` or
`workspace:inference`; other scopes require a Console session.

## Parameters

- `issuer_id: String`

  Tagged ID of the federation issuer.

- `match: BetaFederationRuleMatch`

  Conditions the verified JWT must satisfy for this rule to apply. At least one of `subject_prefix` (other than a wildcard-only value like `*`), `claims`, or `condition` is required; `audience` alone is not sufficient.

  - `audience: String`

    Exact match against the `aud` claim (any element if array). When omitted, the JWT's `aud` must still equal Anthropic's expected audience for the issuer; setting this field overrides that default.

    maxLength: 1024

  - `claims: Hash[Symbol, String]`

    Exact-match `{claim: value}` pairs against top-level claims. Only string-valued claims can be matched; use `condition` for non-string claims.

  - `condition: String`

    CEL expression over claims for logic the structural fields can't express. Must evaluate to a boolean and may reference only the `claims` variable; a constant-true expression (such as `true`) is rejected with 400.

    maxLength: 4096

  - `subject_prefix: String`

    Match the verified JWT `sub` claim. Exact match unless the value ends with `*`, in which case it is a prefix match. Example: `repo:my-org/my-repo:ref:refs/heads/main`.

    maxLength: 1024

- `name: String`

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

  minLength: 1, maxLength: 255

- `oauth_scope: String`

  Space-separated OAuth scopes. OAuth callers may only set `workspace:developer` or `workspace:inference`; other scopes (such as `org:admin`) require a Console session.

  minLength: 1

- `target: BetaServiceAccountTarget`

  Identity that tokens minted via this rule act as. Currently always a `service_account` target.

  - `type: :service_account`

  - `service_account_id: String`

    Tagged ID of the service account to mint tokens for.

  - `service_account_name: String`

    Service account's display name at read time. Ignored on writes.

- `applies_to_all_workspaces: bool`

  When true, enable this rule for every workspace in the org (including workspaces created later).

- `attributes: Hash[Symbol, String]`

  CEL expressions `{name: expr}` extracting named values from claims. Not yet supported; any non-empty value is rejected with 400.

- `description: String`

  Optional free-text description.

  maxLength: 2000

- `token_lifetime_seconds: Integer`

  Lifetime in seconds for access tokens minted via this rule (60-86400). Defaults to 3600 (1h). Minted tokens are capped at `max(60, min(this value, 2 × remaining assertion validity))` seconds.

  minimum: 60, maximum: 86400

- `workspace_id: String`

  Tagged ID of the workspace to enable this rule for. Required unless `applies_to_all_workspaces` is true. Additional workspaces can be added via the `/federation_rules/{federation_rule_id}/workspaces` sub-resource.

- `betas: Array[AnthropicBeta]` (header parameter)

  Optional header to specify the beta version(s) you want to use.

## Returns

- `class BetaFederationRule`

  Authorization rule binding an external OIDC identity to Anthropic.

  Evaluates the match conditions and mints an OAuth access token for the
  resolved target, scoped to a single workspace where the rule is enabled
  (chosen by the caller at exchange time when the rule is enabled for more
  than one). For rules enabled via `workspace_ids` or
  `applies_to_all_workspaces`, the target service account must be a member
  of that workspace (it is implicitly a member of the default workspace);
  rules carrying only the legacy `workspace_id` binding do not enforce
  this.

  - `type: :federation_rule`

  - `id: String`

    Tagged ID of the federation rule.

  - `applies_to_all_workspaces: bool`

    When true, this rule is enabled for every workspace in the org (including ones created after the rule). `workspace_ids` is ignored at exchange time.

  - `archived_at: Time`

    If set, this rule is archived and rejects token exchange.

    format: date-time

  - `archived_by_actor_id: String`

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

  - `attributes: Hash[Symbol, String]`

    CEL expressions extracting named values from claims. Not yet supported; always null.

  - `created_at: Time`

    When this rule was created.

    format: date-time

  - `created_by_actor_id: String`

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

  - `description: String`

    Optional free-text description.

  - `issuer_id: String`

    Tagged ID of the issuer whose tokens this rule accepts.

  - `issuer_name: String`

    Issuer's display name at read time.

  - `match: BetaFederationRuleMatch`

    Conditions the verified JWT must satisfy for this rule to apply. All populated matcher fields must pass.

    - `audience: String`

      Exact match against the `aud` claim (any element if array). When omitted, the JWT's `aud` must still equal Anthropic's expected audience for the issuer; setting this field overrides that default.

      maxLength: 1024

    - `claims: Hash[Symbol, String]`

      Exact-match `{claim: value}` pairs against top-level claims. Only string-valued claims can be matched; use `condition` for non-string claims.

    - `condition: String`

      CEL expression over claims for logic the structural fields can't express. Must evaluate to a boolean and may reference only the `claims` variable; a constant-true expression (such as `true`) is rejected with 400.

      maxLength: 4096

    - `subject_prefix: String`

      Match the verified JWT `sub` claim. Exact match unless the value ends with `*`, in which case it is a prefix match. Example: `repo:my-org/my-repo:ref:refs/heads/main`.

      maxLength: 1024

  - `name: String`

    Admin-chosen slug identifier.

  - `oauth_scope: String`

    Space-separated OAuth scopes granted on the minted token.

  - `target: BetaServiceAccountTarget`

    What this rule targets. Check `type` before reading the other fields. Tokens minted via a rule whose target `type` is `service_account` act as that service account.

    - `type: :service_account`

    - `service_account_id: String`

      Tagged ID of the service account to mint tokens for.

    - `service_account_name: String`

      Service account's display name at read time. Ignored on writes.

  - `token_lifetime_seconds: Integer`

    Lifetime in seconds of access tokens minted via this rule. Minted tokens are capped at `max(60, min(this value, 2 × remaining assertion validity))` seconds.

  - `updated_at: Time`

    When this rule was last updated.

    format: date-time

  - `updated_by_actor_id: String`

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

  - `workspace_id: String`

    Legacy single-workspace binding. Prefer `workspace_ids` and the `/federation_rules/{federation_rule_id}/workspaces` sub-resource for managing workspace enablement.

  - `workspace_ids: Array[String]`

    Tagged IDs of the workspaces this rule is enabled for. May be empty for older rules that only carry the legacy `workspace_id` binding. Ignored at exchange time when `applies_to_all_workspaces` is true (the list may still be non-empty).

## Example

```ruby
require "anthropic"

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

beta_federation_rule = anthropic.beta.organization.federation.rules.create(

  match: {},
  name: "x",
  oauth_scope: "x",
  target: {service_account_id: "svac_01SDCCSbTxrXDpWc1phhtcfK", type: :service_account}
