Automate Your WhatsApp Customer Service with AI: Free Download for n8n
day’s fast-paced business environment, customers expect quick, professional, and efficient communication. Whether you run a landscaping company, a service business, or any client-based operation, keeping up with WhatsApp messages can be overwhelming.
That’s why I created this AI-Powered WhatsApp Agent for Businesses, fully integrated with n8n, Evolution API, Google Calendar, Google Sheets, and OpenAI. This workflow allows your WhatsApp to operate like a real customer service agent — answering text, voice, and image messages, managing bookings, and handling customer requests automatically.
And yes — it’s available for free download.
What This Workflow Can Do
- Understands WhatsApp messages, whether they are text, voice, or images.
- Uses AI to interpret customer inquiries, transcribe voice notes, and analyze images.
- Provides a smart, dynamic menu to customers with service options.
- Manages bookings in Google Calendar automatically, including creating, modifying, and deleting appointments.
- Confirms appointments via WhatsApp with natural, AI-generated responses.
- Handles reservation confirmations, cancellations, and updates in real-time.
- Maintains a record of all customer interactions and bookings in Google Sheets.
How It Works
When a customer sends a message, the agent:

- Processes the message with a detailed AI prompt tailored for customer service in Portuguese or English.
- Replies professionally with options like:
- Book a service

- Request pricing (without giving prices directly)
- Get gardening tips
- Checks Google Calendar to find available slots.
