n8n UnoPim GPT-4o Catalog Chat Assistant Workflow

Turn your UnoPim catalog into a chat-based product knowledge assistant with GPT-4o

The n8n UnoPim GPT-4o Catalog Chat Assistant Workflow lets customers (or internal teams) ask natural-language questions and get up-to-date product catalog answers—powered by OpenAI and live data from your UnoPim instance. No more digging through spreadsheets or hunting for SKUs and attributes.

What this workflow does

• Receives your question through an n8n Chat trigger.
• Uses an OpenAI chat model (e.g., GPT-4o) with a system prompt to act as a UnoPim catalog assistant.
• Maintains conversation context using memory for the last 10 messages, so follow-up questions work naturally.
• Calls the UnoPim API as needed to retrieve catalog data such as products, attributes, and categories (including a configurable result limit).
• Returns a clearly formatted response with the requested catalog details like SKUs, prices, and attributes.

Use cases

• Customer support asks: “Do you have this item in stock?” and gets catalog-referenced answers from UnoPim.
• Pre-sales/product teams ask for bundles, variants, or attribute-based comparisons directly in chat.
• SaaS operators build an internal catalog Q&A for faster product discovery without manual lookups.
• Automation engineers adjust the UnoPim tool configuration (resource/operation and result limit) for different catalog queries.

Technical details

• Integrations: OpenAI (chat model such as GPT-4o) + UnoPim API
• n8n nodes used: code, no op, filter, n8n-nodes-unopimuno pim, sticky note, and manual trigger
• Setup requirements: configure UnoPim API credentials (base URL, client ID, client secret) and an OpenAI API credential in n8n

If you want a practical n8n automation workflow that makes your UnoPim catalog instantly searchable via chat, this GPT-powered assistant is built for you.
