# `GET /v1/shared` — List sessions shared with me

Part of the [Bkper Managed Agent API](https://preview.bkper.com/docs/api/managed-agent.md). Read its guide for authentication, conventions, and examples.

Sessions other people share with the caller, newest updated first: with `book`, those started in that Book; without it, those shared with the caller's verified hosted domain (none without one). Only in the user's own workspace, never an App's (404).
