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.

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 { audience, claims, condition, subject_prefix }

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.

maxLength1024

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.

maxLength4096

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.

maxLength1024

name: String

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

maxLength255

minLength1

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.

minLength1

target: BetaServiceAccountTarget { service_account_id, type, service_account_name }

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

service_account_id: String

Tagged ID of the service account to mint tokens for.

type: :service_account

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.

maxLength2000

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.

maximum86400

minimum60

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]

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

Returns

class BetaFederationRule { id, applies_to_all_workspaces, archived_at, 17 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.
