# Sessions

# Sessions API

This document outlines the API endpoints for managing user sessions in PySpur.
Sessions are used to maintain conversation history in agent spurs.
Each session is tied to a user and a spur.
For quick testing purposes, use the create test user endpoint. It also creates a default test user if doesn't exist.
