This workflow automates outbound calls to qualified leads using VAPI.ai and Google Sheets. Here's how it works and how to set it up. How It Works Read Leads: The workflow starts by reading leads from a Google Sheet where the "AI call status" is marked as "NO" Batch Processing: Leads are processed one at a time (batch size = 1) to ensure proper sequencing Variable Setup: Extracts the phone number and row number from each lead record Trigger VAPI Call: Makes an API call to VAPI.ai to initiate an AI-powered outbound call Update Status: Marks the lead as "YES" in the Google Sheet after the call is triggered to prevent duplicate calls Detailed Setup Guide Prerequisites n8n instance (self-hosted or cloud) Google Sheets account with OAuth2 credentials VAPI.ai account with API access Step 1: Google Sheets Setup Create a Google Sheet with your leads data Ensure you have these columns (adjust if needed): Phone number (column E in the current setup) AI call status (column F in the current setup) Mark all leads you want to call with "NO" in the status column Step 2: Google Sheets Credentials In n8n, go to Credentials > Add New Select "Google Sheets OAuth2 API" Follow the prompts to authenticate with your Google account Name it (e.g., "Google Sheets account 3" as in the example) Step 3: VAPI.ai Setup Get your VAPI.ai API credentials In n8n, go to Credentials > Add New Select "HTTP Header Auth" Add your VAPI authorization header (typically "Bearer YOUR_API_KEY") Name it (e.g., "Header Auth account 4" as in the example).
