Once configured, follow the [Web Integration](/session/documentation/frontend-sdks/web) guide to integrate the SDK into your frontend.

## General concepts

Regardless of which authentication method you use, the Session API follows the same patterns:

* **Management API** (backend) — Configure authentication methods, create users, and manage identifiers using your API key
* **Frontend API** — Authenticate users from the browser through your [custom domain](/session/documentation/domain-names). The API returns JWT access tokens and manages sessions via headers and IndexDB
* **Token verification** (backend) — Verify JWT access tokens on each authenticated request using the [JWKS endpoint](/session/documentation/jwks)

## What's next?

* Set up [Webhooks](/session/documentation/webhooks/introduction) to receive real-time notifications when users are created or sessions change
* Explore the [Management API](/session/api-reference/management/users/list-users) for advanced user management
