Restaurant Voice Booking & Marketing n8n Workflow (VAPI, Sheets, Calendar)

Turn your restaurant leads into booked reservations using voice AI—automatically

This n8n workflow builds a complete Restaurant Voice Booking & Marketing system that combines VAPI-powered voice calls with Excel/Google Sheets lead management. When a new lead is added to your spreadsheet, the automation formats their details, runs marketing campaigns, places personalized voice calls, and logs responses—so your restaurant can scale outreach and booking with less manual work.

What this workflow does

• Captures new leads in Excel: A trigger detects newly added customers in your lead management spreadsheet.
• Prepares lead data: The workflow processes and formats key fields such as name, phone, preferences, and booking history.
• Runs a campaign loop: It iterates through multiple leads to support batch marketing campaigns based on lead data.
• Places personalized voice calls with VAPI: VAPI initiates voice interactions featuring tailored restaurant offers and booking invitations.
• Tracks outcomes back in Excel: Call results and lead responses are written back to your spreadsheet for campaign tracking.
