n8n Webhook Booking Workflow + Telegram Alerts for Appointments

Turn website bookings into instant appointment options—with Telegram emergency alerts

With this n8n Webhook Booking Workflow + Telegram Alerts, you can accept booking messages from your website via webhook, automatically propose three appointment slots, plan follow-ups for reminders/no-shows/reviews, and notify the owner on Telegram only when the request is urgent—then immediately return a ready-to-send reply to the customer.

What this workflow does

• Receives booking requests through an n8n Webhook (POST) containing the customer message and optional contact details (e.g., name, phone, channel).
• Classifies the request by scanning the message for urgency and service keywords, and infers the preferred day/time-of-day.
• Proposes 3 appointment slots and drafts a personalized reply—including requesting a phone number if it’s missing.
• Creates a follow-up plan for reminders, handling no-shows, and supporting review collection.
• Telegram alerts for emergencies only: if the request is marked urgent, the workflow sends a Telegram message to the owner with a customer summary and the first held slot.
• Returns results to the caller by responding to the webhook with the generated reply, offered slots, and the follow-up plan.

Use cases

• A service business booking from a website form: customer sends “ASAP today,” the workflow suggests slots and notifies you on Telegram.
• Appointment intake for multiple service types using keyword detection (e.g., “consultation,” “maintenance,” etc.).
• Ops teams who want consistent appointment responses while keeping owner notifications limited to true emergencies.

Technical details

• n8n nodes: webhook, if, code, telegram, sticky note, and respond to webhook.
• Telegram setup: add Telegram bot credentials and set the chat ID for emergency alerts.
• Customization: update urgent/service keyword lists and adjust slot-generation logic and business hours in the workflow code.
