Business problem

Customer support teams answer the same questions repeatedly on WhatsApp — pricing, hours, policies, product details — taking time away from more complex issues.

Before automation

A support agent reads every incoming WhatsApp message and types a reply manually, even for frequently repeated questions.

The automated workflow

n8n routes incoming WhatsApp messages to an AI agent that searches your knowledge base (FAQs, policies, product info) and replies automatically, escalating to a human when it isn't confident.

How it works

  1. 1An incoming WhatsApp message triggers the workflow.
  2. 2n8n sends the message to an AI agent connected to your knowledge base.
  3. 3The AI drafts a response grounded in your actual documents.
  4. 4Confident responses are sent automatically; uncertain ones are flagged for a human agent.
