# Federation

## Federation › Issuers

### Create Federation Issuer

`BetaFederationIssuer Beta.Organization.Federation.Issuers.Create(parameters, cancellationToken = default)`

**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=csharp).

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

- `IssuerCreateParams parameters`

  - `required string issuerUrl`

    The `iss` claim value to match against.

    minLength: 1

  - `required string name`

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

    minLength: 1, maxLength: 255

  - `bool? checkJti`

    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 jwks`

    How signing keys are obtained. Defaults to OIDC discovery.

    - `class BetaJwksDiscovery`

      JWKS via the issuer's OIDC discovery document.

      - `JsonElement Type = "discovery"`

      - `string? CACertPem`

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

        maxLength: 8192

      - `string? DiscoveryBase`

        Set when the discovery URL differs from `issuer_url`.

    - `class BetaJwksExplicitUrl`

      JWKS fetched from a fixed endpoint.

      - `JsonElement Type = "explicit_url"`

      - `required string Url`

        JWKS endpoint.

        minLength: 1

      - `string? CACertPem`

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

        maxLength: 8192

    - `class BetaJwksInline`

      JWKS supplied directly; no network fetch.

      - `JsonElement Type = "inline"`

      - `required IReadOnlyList<IReadOnlyDictionary<string, JsonElement>> Keys`

        Inline JWK objects.

        minItems: 1

  - `long? maxJwtLifetimeSeconds`

    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 BetaFederationIssuer`

  Registered external OIDC identity provider.

  Records an external IdP the organization trusts for the RFC 7523

### Update Federation Issuer

`BetaFederationIssuer Beta.Organization.Federation.Issuers.Update(parameters, cancellationToken = default)`

**POST** `/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=csharp).

Partially update a federation issuer.

Setting `jwks` replaces the full JWKS shape at once. Archived issuers
cannot be updated; this returns 400. Create a new issuer instead.

Updating an issuer that backs a rule with a scope outside
`workspace:developer` or `workspace:inference` requires a Console
session.

#### Parameters

- `IssuerUpdateParams parameters`

  - `required string federationIssuerID` (path parameter)

    ID of the federation issuer to update.

  - `bool? checkJti`

    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.

  - `string? issuerUrl`

    Replaces the `iss` claim value to match against. For discovery-mode issuers without a `discovery_base`, this is also the URL Anthropic fetches the OIDC discovery document and signing keys from, so changing it repoints the JWKS source. Changing the issuer URL to a well-known shared platform is rejected while any live rule under this issuer would not constrain tenant identity.

    minLength: 1

  - `Jwks? jwks`

    Replaces the entire JWKS configuration.

    - `class BetaJwksDiscovery`

      JWKS via the issuer's OIDC discovery document.

      - `JsonElement Type = "discovery"`

      - `string? CACertPem`

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

        maxLength: 8192

      - `string? DiscoveryBase`

        Set when the discovery URL differs from `issuer_url`.

    - `class BetaJwksExplicitUrl`

      JWKS fetched from a fixed endpoint.

      - `JsonElement Type = "explicit_url"`

      - `required string Url`

        JWKS endpoint.

        minLength: 1

      - `string? CACertPem`

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

        maxLength: 8192

    - `class BetaJwksInline`

      JWKS supplied directly; no network fetch.

      - `JsonElement Type = "inline"`

      - `required IReadOnlyList<IReadOnlyDictionary<string, JsonElement>> Keys`

        Inline JWK objects.

        minItems: 1

  - `bool? jwksPollingDisabled`

    Only `false` is accepted, to re-enable polling after the system pauses it. Polling is paused automatically; sending `true` is rejected.

  - `long? maxJwtLifetimeSeconds`

    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.

    minimum: 1, maximum: 176400

  - `string? name`

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

    minLength: 1, maxLength: 255

  - `IReadOnlyList<AnthropicBeta> betas` (header parameter)

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

### Archive Federation Issuer

`BetaFederationIssuer Beta.Organization.Federation.Issuers.Archive(parameters, cancellationToken = default)`

**POST** `/v1/organizations/federation_issuers/{federation_issuer_id}/archive`

**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=csharp).

Archive a federation issuer.

Idempotent; re-archiving returns the issuer with its original
`archived_at`. Rejected with 400 if any live (non-archived) federation
rule still references the issuer; archive those rules first (a rule's
issuer cannot be changed), or recreate them against another issuer.

#### Parameters

- `IssuerArchiveParams parameters`

  - `required string federationIssuerID` (path parameter)

    ID of the federation issuer to archive.

  - `IReadOnlyList<AnthropicBeta> betas` (header parameter)

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

## Federation › Rules

### Create Federation Rule

`BetaFederationRule Beta.Organization.Federation.Rules.Create(parameters, cancellationToken = default)`

**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=csharp).

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

- `RuleCreateParams parameters`

  - `required string issuerID`

    Tagged ID of the federation issuer.

  - `required BetaFederationRuleMatch match`

    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.

  - `required string name`

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

    minLength: 1, maxLength: 255

  - `required string oauthScope`

    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

  - `required BetaServiceAccountTarget target`

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

  - `bool appliesToAllWorkspaces`

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

  - `IReadOnlyDictionary<string, string>? attributes`

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

  - `string? description`

    Optional free-text description.

    maxLength: 2000

  - `long tokenLifetimeSeconds`

    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

  - `string? workspaceID`

    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.

  - `IReadOnlyList<AnthropicBeta> betas` (header parameter)

#### 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.

  - `JsonElement Type = "federation_rule"`

  - `required string ID`

    Tagged ID of the federation rule.

  - `required bool AppliesToAllWorkspaces`

    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.

  - `required DateTimeOffset? ArchivedAt`

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

    format: date-time

  - `required string? ArchivedByActorID`

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

  - `required IReadOnlyDictionary<string, string>? Attributes`

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

  - `required DateTimeOffset CreatedAt`

    When this rule was created.

    format: date-time

  - `required string? CreatedByActorID`

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

  - `required string? Description`

    Optional free-text description.

  - `required string IssuerID`

    Tagged ID of the issuer whose tokens this rule accepts.

  - `required string? IssuerName`

    Issuer's display name at read time.

  - `required BetaFederationRuleMatch Match`

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

    - `string? Audience`

      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

    - `IReadOnlyDictionary<string, string>? Claims`

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

    - `string? Condition`

      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

    - `string? SubjectPrefix`

      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

  - `required string Name`

    Admin-chosen slug identifier.

  - `required string OAuthScope`

    Space-separated OAuth scopes granted on the minted token.

  - `required BetaServiceAccountTarget Target`

    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.

    - `JsonElement Type = "service_account"`

    - `required string ServiceAccountID`

      Tagged ID of the service account to mint tokens for.

    - `string? ServiceAccountName`

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

  - `required long TokenLifetimeSeconds`

    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.

  - `required DateTimeOffset UpdatedAt`

    When this rule was last updated.

    format: date-time

  - `required string? UpdatedByActorID`

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

  - `required string? WorkspaceID`

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

  - `required IReadOnlyList<string> WorkspaceIds`

    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).

#### 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.

  - `JsonElement Type = "federation_rule"`

  - `required string ID`

    Tagged ID of the federation rule.

  - `required bool AppliesToAllWorkspaces`

    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.

  - `required DateTimeOffset? ArchivedAt`

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

    format: date-time

  - `required string? ArchivedByActorID`

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

  - `required IReadOnlyDictionary<string, string>? Attributes`

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

  - `required DateTimeOffset CreatedAt`

    When this rule was created.

    format: date-time

  - `required string? CreatedByActorID`

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

  - `required string? Description`

    Optional free-text description.

  - `required string IssuerID`

    Tagged ID of the issuer whose tokens this rule accepts.

  - `required string? IssuerName`

    Issuer's display name at read time.

  - `required BetaFederationRuleMatch Match`

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

    - `string? Audience`

      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

    - `IReadOnlyDictionary<string, string>? Claims`

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

    - `string? Condition`

      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

    - `string? SubjectPrefix`

      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

  - `required string Name`

    Admin-chosen slug identifier.

  - `required string OAuthScope`

    Space-separated OAuth scopes granted on the minted token.

  - `required BetaServiceAccountTarget Target`

    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.

    - `JsonElement Type = "service_account"`

    - `required string ServiceAccountID`

      Tagged ID of the service account to mint tokens for.

    - `string? ServiceAccountName`

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

  - `required long TokenLifetimeSeconds`

    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.

  - `required DateTimeOffset UpdatedAt`

    When this rule was last updated.

    format: date-time

  - `required string? UpdatedByActorID`

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

  - `required string? WorkspaceID`

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

  - `required IReadOnlyList<string> WorkspaceIds`

    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

```csharp
using System;
using Anthropic.Models.Beta.Organization.Federation.Rules;

RuleRetrieveParams parameters = new()
{
    FederationRuleID = "federation_rule_id"
};

var betaFederationRule = await client.Beta.Organization.Federation.Rules.Retrieve(parameters);

Console.WriteLine(betaFederationRule);

### Update Federation Rule

`BetaFederationRule Beta.Organization.Federation.Rules.Update(parameters, cancellationToken = default)`

**POST** `/v1/organizations/federation_rules/{federation_rule_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=csharp).

Partially update a federation rule.

`issuer_id` is immutable. `match` and `target` are replaced as whole
objects when set. Referenced service accounts and workspaces must exist
in your organization; invalid references are rejected with a 400 error.
Archived rules cannot be updated; this returns 400. Create a new rule
instead. 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`). On these issuers the
requirement is re-checked on every update; if an existing rule's stored
match does not yet constrain tenant identity, any update (even a rename
or description change) must also supply a conforming `match` in the same
request. OAuth callers may only manage rules whose `oauth_scope` is
`workspace:developer` or `workspace:inference`; other scopes require a
Console session.

#### Parameters

- `RuleUpdateParams parameters`

  - `required string federationRuleID` (path parameter)

    ID of the federation rule to update.

  - `bool? appliesToAllWorkspaces`

    When true, enables this rule for every workspace in the org (including workspaces created later). Setting `false` is rejected with 400 if no workspace would remain enabled; a rule with only a legacy `workspace_id` binding continues to mint.

  - `IReadOnlyDictionary<string, string>? attributes`

    Replaces the CEL expressions `{name: expr}` extracting named values from claims. Send null to clear them. Not yet supported; any non-empty value is rejected with 400.

  - `string? description`

    Replaces the description. Omit to leave unchanged; send `null` to clear (the field is stored as an empty string).

    maxLength: 2000

  - `BetaFederationRuleMatch? match`

    Replaces the entire match object. All populated matcher fields must pass.

  - `string? name`

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

    minLength: 1, maxLength: 255

  - `string? oauthScope`

    Replaces the space-separated OAuth scopes granted on minted tokens. OAuth callers may only set `workspace:developer` or `workspace:inference`; other scopes (such as `org:admin`) require a Console session.

    minLength: 1

  - `BetaServiceAccountTarget? target`

    Replaces the entire target object. Currently always a `service_account` target.

  - `long? tokenLifetimeSeconds`

    Replaces the lifetime in seconds for access tokens minted via this rule (60-86400). Minted tokens are capped at `max(60, min(this value, 2 × remaining assertion validity))` seconds.

    minimum: 60, maximum: 86400

  - `string? workspaceID`

    Replaces the existing single workspace enablement (the previous one is removed). Rejected with 400 if the rule is enabled for more than one workspace; use the `/federation_rules/{federation_rule_id}/workspaces` sub-resource instead.

  - `IReadOnlyList<AnthropicBeta> betas` (header parameter)

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

### Archive Federation Rule

`BetaFederationRule Beta.Organization.Federation.Rules.Archive(parameters, cancellationToken = default)`

**POST** `/v1/organizations/federation_rules/{federation_rule_id}/archive`

**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=csharp).

Archive a federation rule.

Token exchange through this rule stops immediately. Idempotent;
re-archiving returns the rule with its original `archived_at`. Archiving
clears the rule's workspace targeting (`workspace_id` and
`workspace_ids` are emptied). Tokens already minted before archive
remain valid until they expire. OAuth callers may only manage rules
whose `oauth_scope` is `workspace:developer` or `workspace:inference`;
other scopes require a Console session.

#### Parameters

- `RuleArchiveParams parameters`

  - `required string federationRuleID` (path parameter)

    ID of the federation rule to archive.

  - `IReadOnlyList<AnthropicBeta> betas` (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.

  - `JsonElement Type = "federation_rule"`

  - `required string ID`

    Tagged ID of the federation rule.

  - `required bool AppliesToAllWorkspaces`

    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.

  - `required DateTimeOffset? ArchivedAt`

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

    format: date-time

  - `required string? ArchivedByActorID`

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

  - `required IReadOnlyDictionary<string, string>? Attributes`

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

  - `required DateTimeOffset CreatedAt`

    When this rule was created.

    format: date-time

  - `required string? CreatedByActorID`

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

  - `required string? Description`

    Optional free-text description.

  - `required string IssuerID`

    Tagged ID of the issuer whose tokens this rule accepts.

  - `required string? IssuerName`

    Issuer's display name at read time.

  - `required BetaFederationRuleMatch Match`

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

    - `string? Audience`

      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

    - `IReadOnlyDictionary<string, string>? Claims`

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

    - `string? Condition`

      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

    - `string? SubjectPrefix`

      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

  - `required string Name`

    Admin-chosen slug identifier.

  - `required string OAuthScope`

    Space-separated OAuth scopes granted on the minted token.

  - `required BetaServiceAccountTarget Target`

    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.

    - `JsonElement Type = "service_account"`

    - `required string ServiceAccountID`

      Tagged ID of the service account to mint tokens for.

    - `string? ServiceAccountName`

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

  - `required long TokenLifetimeSeconds`

    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.

  - `required DateTimeOffset UpdatedAt`

    When this rule was last updated.

    format: date-time

  - `required string? UpdatedByActorID`

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

  - `required string? WorkspaceID`

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

  - `required IReadOnlyList<string> WorkspaceIds`

    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

```csharp
using System;
using Anthropic.Models.Beta.Organization.Federation.Rules;

RuleArchiveParams parameters = new()
{
    FederationRuleID = "federation_rule_id"
};

var betaFederationRule = await client.Beta.Organization.Federation.Rules.Archive(parameters);

Console.WriteLine(betaFederationRule);

## Federation › Rules › Workspaces

### Add Federation Rule Workspace

`BetaFederationRuleWorkspace Beta.Organization.Federation.Rules.Workspaces.Add(parameters, cancellationToken = default)`

**POST** `/v1/organizations/federation_rules/{federation_rule_id}/workspaces`

**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=csharp).

Enable a federation rule for a workspace.

Idempotent; re-enabling returns the existing enablement. The rule and
workspace must both belong to your organization. Membership of the
rule's target service account in this workspace is not checked at
enablement: token exchange into this workspace is rejected unless the
target is a member (it is implicitly a member of the default workspace).
Archived rules are rejected with 400. OAuth callers may only manage rules
whose `oauth_scope` is `workspace:developer` or `workspace:inference`;
other scopes require a Console session.

#### Parameters

- `WorkspaceAddParams parameters`

  - `required string federationRuleID` (path parameter)

    ID of the federation rule.

  - `required string workspaceID`

    Tagged ID of the workspace to enable this rule for.

  - `IReadOnlyList<AnthropicBeta> betas` (header parameter)

### List Federation Rule Workspaces

`WorkspaceListPage Beta.Organization.Federation.Rules.Workspaces.List(parameters, cancellationToken = default)`

**GET** `/v1/organizations/federation_rules/{federation_rule_id}/workspaces`

**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=csharp).

List workspaces where this federation rule is enabled.

Returns all workspace enablements in a single response; the `limit` and
`page` parameters are accepted but have no effect, and `next_page` is
always `null`. Returns explicit per-workspace enablements only; for
rules with `applies_to_all_workspaces` or a legacy single
`workspace_id`, check those fields on the rule itself.

#### Parameters

- `WorkspaceListParams parameters`

  - `required string federationRuleID` (path parameter)

    ID of the federation rule.

  - `long limit` (query parameter)

    Number of results per page.

    minimum: 1, maximum: 100

  - `string? page` (query parameter)

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

  - `IReadOnlyList<AnthropicBeta> betas` (header parameter)

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

#### Returns

- `class BetaFederationRuleWorkspace`

  - `JsonElement Type = "federation_rule_workspace"`

  - `required DateTimeOffset CreatedAt`

    When this workspace was enabled for the rule.

    format: date-time

  - `required string? CreatedByActorID`

    Tagged ID (`user_...` or `svac_...`) of the actor that enabled this workspace for the rule, if known.

  - `required string FederationRuleID`

    Tagged ID of the federation rule.

  - `required string WorkspaceID`

    Tagged ID of the workspace this rule is enabled for.

  - `required string? WorkspaceName`

    Workspace display name. Populated when listing; null in the enable response.

#### Example

```csharp
using System;
using Anthropic.Models.Beta.Organization.Federation.Rules.Workspaces;

WorkspaceListParams parameters = new()
{
    FederationRuleID = "federation_rule_id"
};

var page = await client.Beta.Organization.Federation.Rules.Workspaces.List(parameters);
await foreach (var item in page.Paginate())
{
    Console.WriteLine(item);
}
```

##### Response (200)

```json
{
  "data": [
    {
      "created_at": "2024-10-30T23:58:27.427722Z",
      "created_by_actor_id": "created_by_actor_id",

### Remove Federation Rule Workspace

`WorkspaceRemoveResponse Beta.Organization.Federation.Rules.Workspaces.Remove(parameters, cancellationToken = default)`

**DELETE** `/v1/organizations/federation_rules/{federation_rule_id}/workspaces/{workspace_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=csharp).

Disable a federation rule for a workspace.

Idempotent; succeeds even if the enablement was already removed. OAuth
callers may only manage rules whose `oauth_scope` is
`workspace:developer` or `workspace:inference`; other scopes require a
Console session.

#### Parameters

- `WorkspaceRemoveParams parameters`

  - `required string federationRuleID` (path parameter)

    ID of the federation rule.

  - `required string workspaceID` (path parameter)

    ID of the workspace to disable for.

  - `IReadOnlyList<AnthropicBeta> betas` (header parameter)

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