Customer Auth for Chat Support: OpenAI + Redis Sessions

This n8n workflow provides a flexible customer authentication system for chat-based support agents. It allows guest users to start conversations immediately and authenticate mid-session via a unique login URL generated by an OpenAI agent, using Redis to maintain session context across interactions. Sessions begin blank for guests and are populated with customer profiles upon successful login, dynamically updating the agent's system prompt for personalized responses.

The flow starts with a chat trigger and Redis node to fetch or initialize session data. The OpenAI conversational agent detects guest status and prompts a secure login URL (with sessionID as query param) when appropriate or requested. Users access an n8n-hosted form for credentials; upon validation (e.g., against a database like PostgreSQL), the matching Redis session is updated with profile data. Subsequent messages retrieve this data, enabling the agent to recognize authenticated customers.

Benefits include seamless UX without pre-login barriers, scalable session persistence, and AI-driven personalization. Ideal for enterprise customer support, e-commerce helpdesks, or service chatbots needing conditional access to user data. Security note: Template for illustration; harden auth, encryption, and validation for production. Saves development time on complex auth flows.
