LeadFlow AI: n8n Webhook + OpenAI + Airtable + Slack Lead Automation
LeadFlow AI: n8n Webhook + OpenAI + Airtable + Slack Lead Automation This workflow captures leads via webhook, validates and deduplicates them, uses OpenAI to score and summarize intent and sends high-quality leads (score > 70) to Airtable and Slack for immediate sales action. Quick Setup (Start in Minutes) Login to your n8n account and import this workflow Connect your form/API to the webhook endpoint Add Airtable credentials and select base/table Add OpenAI API credentials Connect Slack and choose a channel Activate workflow and test with sample data What It Does This workflow automates your entire lead handling process from capture to qualification and notification. When a new lead is submitted through a webhook, the system extracts and standardizes the data, ensuring all required fields are present and usable. Next, it checks if the lead already exists in Airtable using the email address. If the lead is new, it is sent to an AI model that evaluates the message content and assigns a score, category (Hot/Warm/Cold) and a short summary. Finally, only high-intent leads (score greater than 70) are stored in Airtable and instantly sent to Slack. This ensures your sales team focuses only on the most valuable opportunities without manual filtering.
