Webhook Lead Capture & AI Qualification with Slack Alerts

Capture leads via Webhook, auto-qualify them with OpenAI, and alert your team in Slack

This n8n workflow receives new lead submissions through a Webhook, validates and enriches the data with an OpenAI qualification score (1–10), logs the processed result for Google Sheets/CRM handling, and sends a “new lead” notification to Slack—then returns a JSON response to the webhook caller.

What this workflow does

• Receives lead data via a POST request on a webhook endpoint (at minimum: name and email; optionally company and source).
• Validates and normalizes inputs: checks required fields, validates email format, normalizes optional fields, and adds timestamps.
• Qualifies the lead with OpenAI: sends the lead details to OpenAI Chat Completions (gpt-4o-mini) to generate a 1–10 qualification score, reasoning, and a suggested next action.
• Parses results safely: flags the lead as qualified when the score is 7 or higher, and includes a fallback default score if the model output is not valid JSON.
• Prepares a logging payload: creates a processed result payload intended for Google Sheets/CRM logging (simulated in this template) and generates a placeholder row reference.
• Notifies via Slack: posts a formatted “new lead” alert to Slack using a Slack Incoming Webhook.
• Returns a JSON response back to the webhook caller with the processing outcome.

Use cases

• Turn form submissions into actionable sales leads with AI-assisted qualification.
• Route high-intent leads (score ≥ 7) faster by triggering Slack alerts for your sales/support team.
• Centralize lead intake from SaaS apps or landing pages into Google Sheets/CRM-ready records.

Technical details

• n8n nodes/blocks used: code, webhook, http request, respond to webhook.
• Integrations: OpenAI Chat Completions (gpt-4o-mini) and Slack Incoming Webhook.
• Core behavior: validates required fields and email format; computes qualification score (1–10) and qualified flag (≥ 7); posts to Slack; returns JSON.

Best for: n8n users, automation engineers, and SaaS operators who need a reliable webhook lead capture + AI qualification workflow with real-time Slack alerts.
