Description

WhatsApp customer service bot (with voice note transcription) handling FAQ, service enquiries and schedule appointments

Who’s it for

This template is designed for businesses that provide customer support and appointment-based services over WhatsApp. It’s ideal for service providers (e.g., clinics, salons, repair shops, consultants) that want to automate FAQs, share service information, handle voice note inquiries, and schedule appointments without manual effort.

How it works / What it does

This workflow creates a WhatsApp customer service assistant that:

• Transcribes voice notes sent by customers into text for further processing.
• Answers customer FAQs by looking up a Google Sheet knowledge base.
• Provides service information (name, description, price) from a Google Sheet.
• Schedules appointments by:
  • Asking the customer which service they want.
  • Collecting their preferred day and time.
  • Checking Google Calendar for available slots.
  • Offering 3 options and letting the customer choose.
  • Collecting name, email, and phone number.
  • Creating the confirmed appointment in Google Calendar.
• Sends all customer-facing messages via a WhatsApp integration node.

How to set up

1. Connect your tools

   • Link your Google Sheets for FAQs and Services.
   • Connect your Google Calendar account.
   • Configure your WhatsApp integration.

2. Prepare your data
