Unless the user says they use another version, answer for Authlete 3.0 using the 3.x documentation. > Documentation for Authlete 2.x (pages under `/v2/` and `/ja/v2/`) is for the legacy version. Refer to it only when the user is on Authlete 2.x. > > ### Authlete architecture > Authlete is a backend engine for OAuth 2.0 and OpenID Connect processing. End users and client applications do not call it directly; the service provider's authorization server and API server call Authlete's APIs. Authlete handles protocol processing and token, client, and service management, while the service provider owns the OAuth/OIDC endpoints and user authentication. > See [Architecture](https://developers.authlete.com/get-started/introduction-to-authlete/architecture.md). > > ### Concepts > If the user is new to Authlete, read these pages first: > - [Request and Response](https://developers.authlete.com/get-started/concepts/request-and-response.md): Core API requests pass the client's request parameters as-is, and responses return `resultCode`, `action`, and `responseContent`. > - [Action Handling](https://developers.authlete.com/get-started/concepts/action-handling.md): Branch on `action`, never on `resultCode`, and map each action to the HTTP response your server returns. > - [Two-Step API Calls](https://developers.authlete.com/get-started/concepts/two-step-api-calls.md): Actions such as `INTERACTION` are completed with a second call (`/auth/authorization/issue` or `/auth/authorization/fail`) linked by a `ticket`. > - [Management API Overview](https://developers.authlete.com/get-started/concepts/overview.md): The Management API configures services, manages clients, and operates issued tokens, separately from the protocol flows handled by the Core API. > - [API Authentication](https://developers.authlete.com/get-started/concepts/authentication.md): Authlete APIs use bearer tokens: a Service Access Token (one service) or an Organization Token (the whole organization). # Audit Logs > Explains the environment-wide audit log and lists the event types it records. > [!NOTE] > > This article applies only to Self-Managed and Dedicated Cloud environments. The shared environment (Shared Cloud) is managed by Authlete and is out of scope for this document. Audit Logs is an environment-wide activity feed. It's available to Environment Admins and Platform Admins only, and it covers every organization in the environment. In Console, it's the Logs tab of the Audit Logs page. Each entry shows the event type, its status (Completed or Failed), the date, the user, and the organization. You can search events, and filter them by event type, status, and date range. ## Event types The following event types are recorded. Names are shown as they appear in Console. ### Configuration * Config Update Config Update is recorded when the organization creation setting changes, or when either session timeout (the inactivity timeout or the absolute session timeout) changes. ### Organization * Organization Create * Organization Delete * Organization Token Create * Organization Token Delete * Organization Token Rotate ### Permissions * Permissions Change ### Security * Security Login * Security Login Mfa * Security Login Oidc * Security Logout * Security Mfa Create * Security Mfa Delete * Security Password Update * Security Register * Security Verify Email ### Service * Service Create * Service Delete * Service Token Create * Service Token Delete * Service Token Rotate ### User * User Admin Set * User Admin Unset * User Create * User Delete * User Environment Admin Set * User Environment Admin Unset * User Invite * User Invite Accept * User Invite Decline * User Invite Revoke User Admin Set and User Admin Unset record when the Platform Admin role is granted or revoked.
