Score BANT Inbound Leads with Google Gemini via Webhook (n8n)

Instantly BANT-Score Inbound Leads with Google Gemini (via Webhook) in n8n

Turn raw form submissions into structured BANT-qualified lead results. This n8n workflow receives lead data through a webhook, validates key fields, uses Google Gemini to score leads on Budget, Authority, Need, and Timeline, and returns a clean JSON response with a 0–100 score and recommended next action.

What this workflow does

• Receives inbound lead data via an n8n webhook using a POST request.
• Validates required fields (at minimum: lead_email and company), then calculates a BANT completeness percentage.
• Scores the lead with Google Gemini using a Gemini-powered AI Agent, classifying each lead as qualified, needs_research, or unqualified and assigning a 0–100 score with hot/warm/cold categorization and a recommended next action.
• Normalizes the AI output into a consistent JSON structure by parsing Gemini’s JSON, adding metadata (status, timestamps, and an event id).
• Handles errors safely by converting model or formatting issues into a structured error object and returning it as the webhook response.

Use cases

• SaaS lead intake: send website or in-app form submissions to the webhook and immediately receive BANT scoring for routing.
• Sales ops triage: prioritize outreach using the hot/warm/cold score and next action recommendation.
• Workflow-driven qualification: integrate with an existing lead source that can POST payloads including BANT fields like budget_status, decision_maker_check, pain_point_validation, and timeline_proximity.
