API execution models: synchronous generation supports low-latency, single-document requests; asynchronous batch generation supports high-throughput scheduled output. Idempotency keys, correlation IDs, callback/webhook status, scoped authorization and retry-safe processing are shown as neutral enterprise patterns.

Authentication / authorization: enterprise access is separated into human sign-in and service-to-service access. The lab demonstrates SSO, MFA, federation, RBAC, scoped API credentials, session controls and audit correlation.

Human Authentication SSO / federation

OIDC / OAuth 2.0

Primary web SSO profile for browser users. Authorization Code + PKCE, short-lived access token, refresh policy, issuer and audience validation.

SSOPKCE

SAML 2.0

Federation option for enterprise identity providers where SAML remains the established sign-on protocol.

Federation

MFA

Step-up authentication for administrative, publishing and sensitive document operations.

Required for Admin

Session Controls

Idle timeout, absolute session lifetime, re-authentication for privileged actions and logout propagation.

Policy

Service Authentication machine identity

OAuth 2.0 Client Credentials

Server-to-server generation requests using scoped client identity rather than interactive user sessions.

APIScopes

JWT Validation

Validate signature, issuer, audience, expiration, not-before and correlation claims before accepting generation traffic.

Signed

mTLS / Secret Rotation

Optional mutual TLS for trusted services; rotate certificates, client secrets and signing keys without application downtime.

High Assurance
