Create Federation Rule

FederationRule 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.

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 FederationRuleMatch 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.

minLength1
maxLength255
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.

minLength1
required ServiceAccountTarget 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).

string? description

Optional free-text description.

maxLength2000
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.

minimum60
maximum86400
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.

Returns
class FederationRule { Type = "federation_rule"; ID; AppliesToAllWorkspaces; /* 15 more */ }

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.
