Create Federation Issuer

$client->beta->organization->federation->issuers->create(string issuerURL, string name, ?bool checkJTI, ?JWKS jwks, ?int maxJWTLifetimeSeconds, ?list<AnthropicBeta> betas): BetaFederationIssuer
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.

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
issuerURL: string

The iss claim value to match against.

name: string

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

checkJTI?:optional bool

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?:optional JWKS

How signing keys are obtained. Defaults to OIDC discovery.

maxJWTLifetimeSeconds?:optional int

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.

betas?:optional list<AnthropicBeta>

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

Returns
class BetaFederationIssuer { $type = 'federation_issuer'; $id; $archivedAt; /* 12 more */ }
