N8N Lead Scoring Workflow: Groq + Google Sheets + Slack/Telegram

Instant AI Lead Scoring for Your Web Forms (Groq + Google Sheets + Slack/Telegram)

Turn every incoming web form submission into a scored lead—hot, warm, or cold—using Groq, automatically save results to Google Sheets, and notify your team in Slack (with Telegram alerts for hot leads).

What this workflow does

• Receives leads via webhook: The workflow accepts inbound lead data through an n8n webhook using a POST request.
• Normalizes form fields: It cleans and maps raw payload fields into a consistent set: name, email, phone, company, message, submitted time.
• Scores buying intent with Groq: The workflow sends lead details to Groq via a chat model prompt, then parses the response into structured JSON containing a score, tier (hot/warm/cold), and reasoning.
• Validates AI output: If the AI score/tier is missing or invalid, the workflow falls back to a manual-review result to keep your pipeline reliable.
• Saves every lead to Google Sheets: Each lead, including score, tier, and reasoning, is appended to your selected worksheet.
• Notifies the right people: For hot leads, it sends a detailed alert in Telegram and posts a summary in Slack. For other tiers, it only posts the Slack summary.

Use cases

• SaaS teams routing high-intent inbound requests to sales faster.
• Automation engineers building lead scoring pipelines with Groq + n8n.
• Operators who want every lead tracked in Google Sheets with transparent AI reasoning.
