AI WhatsApp Real Estate Lead Qualification with n8n

Qualify real estate leads on WhatsApp with AI—automatically, inside n8n

This n8n workflow uses Google Gemini to run an AI lead-qualification chat for inbound WhatsApp messages. It responds to the lead on WhatsApp, checks qualification rules, and—when qualified—notifies your broker and can optionally create a Google Calendar site-visit event.

What this workflow does

• Receives inbound WhatsApp messages via a POST webhook from the Evolution API (triggered when a WhatsApp event hits your workflow URL).
• Filters only inbound text by checking for messages.upsert events that are not sent by your own WhatsApp account.
• Extracts lead details from the webhook payload (message text, phone number, display name, and Evolution instance name) and immediately acknowledges the webhook.
• Runs an AI qualification conversation using a Google Gemini–powered agent with conversation memory, generating the next WhatsApp reply and qualification fields (e.g., budget confirmation and timeline bucket).
• Evaluates qualification rules based on the parsed AI output.
• If the lead is qualified: sends a WhatsApp notification to the broker through Evolution API and can optionally create a Google Calendar event for a site visit.
• If not qualified: continues the nurture conversation by sending the AI-generated reply back to the lead on WhatsApp.

Use cases

• Turn WhatsApp inquiries into qualified real estate leads without manual follow-ups.
• Use AI to ask consistent qualification questions (budget/timeline) and route only strong leads to brokers.
• When a lead is ready, automatically propose and schedule a Google Calendar site visit.

Technical details

• Nodes/logic used: webhook, if, set, code, http request, and google calendar.
