Helpful for business development and pipeline building. Improves internal consulting operations and productivity.

Auto-Call Leads from Google Sheets with VAPI → Log Results + Book Calendar This workflow calls new leads from a Google Sheet using VAPI, saves the call results, and (if there’s a booking request) creates a Google Calendar event automatically. Benefits Auto-call each new lead from your call list Save full call outcomes back to Google Sheets Parse “today/tomorrow + time” into a real datetime (IST) Auto-create calendar events for bookings/deliveries Batch-friendly to avoid rate limits How It Works Trigger: New row in Google Sheets (call_list). Prepare: Normalize phone (adds +), then process in batches. Call: Send number to VAPI (/call) with your assistantId + phoneNumberId. Receive: VAPI posts results to your Webhook. Store: Append/Update Google Sheet with: name, role, company, phone, email, interest level, objections, next step, notes, etc. Parse Time: Convert today/tomorrow + HH:MM AM/PM to start/end in IST (+1 hour). Book: Create Google Calendar event with the parsed times. Respond: Send response back to VAPI to complete the cycle.
