Description

Overview

• This workflow is an AI-powered Dental Appointment Assistant that automates appointment booking, rescheduling, and cancellations through Telegram or a Webhook.
• It uses intelligent agents to understand user intent, gather details, manage Google Calendar events, update records in Google Sheets, and send confirmation emails — creating a fully automated and customizable booking system suitable for any business, not just dental clinics.

How It Works

1. User Interaction

• The workflow can be triggered via Telegram, Webhook, and can easily be extended to WhatsApp or Facebook Messenger.
• The Planning Agent starts the conversation and collects essential details like:
  • Appointment type (book, update, or delete)
  • Date and time preference
  • Service type or reason for visit
  • Personal details (name, email, etc.)
• Based on the user’s intent, it routes the conversation to the appropriate booking flow.

2. Booking Flow

• The Booking Agent handles the actual scheduling logic.
• It interacts with Google Calendar to:
  • Create new events for fresh appointments
  • Update existing events for reschedules
  • Delete events for cancellations
• It ensures proper validation (availability, overlaps, etc.) before confirming any calendar changes.

3. Post-Booking Actions

• Once the booking action is completed:
  • The Mail and Sheet Entry Agent updates the Google Sheet with user details such as:
    • Name
    • Email
    • Appointment date & time
    • Status (booked/updated/cancelled)
    • Short description of the appointment
  • Sends an email confirmation to the user (for all actions — create, update, or delete).
  • Sends a final message via Telegram (or chosen platform) confirming the status of the appointment.

How to Use

• Trigger the workflow via Telegram or a Webhook URL.
• The AI assistant will guide the user step-by-step through booking, updating, or cancelling an appointment.
• Once confirmed, the system:
  • Updates Google Calendar automatically
  • Logs the appointment details in Google Sheets
  • Sends an email and chat confirmation message to the user
