What it is
This is an n8n workflow we built and use ourselves: it listens for incoming WhatsApp Business messages, drafts a reply with Claude Haiku, sends it automatically, and — this is the part most "AI auto-reply" templates skip — escalates to Slack with full context whenever it isn't confident about the answer. No silent failures, no made-up answers sent to a real customer.
It's a $19 one-time purchase, instant download, built by the same team that runs this site.
What's included
- Ready-to-import n8n workflow JSON — drag it into your n8n instance and connect your own WhatsApp Business API and Claude API keys.
- Handles Meta's webhook verification automatically (the part that trips up most people setting up WhatsApp Business API for the first time).
- Escalates uncertain replies to Slack with full context, so a human sees exactly what the customer asked and what the AI wasn't sure about.
- Setup README included.
Who it's for
Small businesses and solo operators running customer support over WhatsApp who want first-response coverage without hiring someone to sit on the app all day — and who want a safety net instead of a bot that confidently makes things up.
What it doesn't do
It's a focused workflow, not a full helpdesk platform. There's no CRM integration, no ticketing system, no analytics dashboard — just message in, AI draft, send or escalate. If you need those, this is a solid first layer to build on top of, not a replacement for them.
