I’ve built a complete web app with a CRM, pipelines, dashboards, and AI agents, using n8n as part of the backend for the AI agent functionality. Currently, the system only works for one user at a time, with memory and requests being tied to a single user. Is there a way to manage multiple users and handle individual requests within a single n8n workflow, while ensuring that each user’s data and memory are kept separate? Or is there a workaround to make this work?
