Triage Website Leads with n8n Webhooks + Google Gemini

Triage every website inquiry instantly with n8n Webhooks + Google Gemini

Stop treating leads like a queue. This n8n workflow receives your website form submissions via webhooks, uses Google Gemini to classify each inquiry as urgent, high, normal, or planned with a short summary and a suggested next step—and returns the result to your site as JSON immediately.

What this workflow does

• Receives form submissions through an n8n webhook endpoint.
• Validates the request body and blocks spam using a honeypot field.
• Enforces rate limits per hour and per day using n8n static workflow data (BUSINESS, SERVICES, MAX_PER_HOUR, MAX_PER_DAY).
• If valid, sends the inquiry details to the Google Gemini generateContent endpoint and requests a strict JSON classification.
• Parses and validates Gemini’s JSON response to extract: priority, priority text, summary bullets, and the suggested next step.
• Returns either the AI classification or a rejection/error reason back to your website as JSON via webhook response.

Use cases

• Your website form is sending many inquiries—Gemini triages them instantly so urgent leads don’t get buried.
• Multiple service lines require different routing—use the business/service context and rate limits in the workflow.
• You need automated lead categorization with consistent outputs (strict JSON) for downstream handling.

Technical details

• n8n nodes/tools: webhook, if, code, http request, respond to webhook (plus sticky note for clarity).
• Integration: Google Gemini (PaLM) via API credential and HTTP request to generateContent.
• Required setup: add a Gemini API key (free tier works for testing), update BUSINESS/SERVICES and rate limits, set webhook Allowed Origins to your domain, and ensure your form posts required fields (service, answers object, message, contactPreference, and an empty honeypot field such as “website”).
