Marketplace Q&A Automation

Automated public answers for marketplace questions with compliance rules and logging.

Marketplace API OAuth n8n LLMs Google Sheets

System design and workflow engineering

Public marketplace questions required fast, compliant answers tied to a shared product knowledge base — not open-ended chat.

A polling workflow that detects unanswered questions, generates short compliant answers from a knowledge base and posts them through the marketplace API with full logging.

Marketplace API (OAuth) → n8n scheduler → knowledge base (Google Sheets) → LLM generation with compliance constraints → API publish → interaction log.

Unanswered question detection, compliant answer generation, API publishing and audit logging.

  • Treat each answer as public and final, not conversational
  • Encode platform compliance rules before generation
  • Log every interaction for review
