Why connect Telegram to Google Calendar
Booking bots are a common Telegram use case for clinics, salons, consultants and coworking spaces. We connect Google Calendar (or Calendly) so availability, bookings and reminders stay in sync with the calendar your team already uses.
How the integration works
- Auth. OAuth for each staff calendar or a service account on Workspace.
- Booking. Mini App shows free slots, creates events with customer details.
- Reminders. Bot sends confirmations, reminders and reschedule links.
- Payments. Deposits via Stars or Stripe.
Typical flows
- Pick a slot → event created → confirmation
- 24h reminder → reschedule button
- No-show follow-up
