What it does

Watch Full Step-by-step Guide Video here: https://www.youtube.com/watch?v=GzWO71lyI8 AI Agent – Processes the message to determine the user's intent (booking or canceling) and extracts necessary details like date, time, and participant names. Google Calendar Node – Depending on the intent: Booking: Creates a new event in Google Calendar with the extracted details. Canceling: Searches for the specified event and deletes it from the calendar. Telegram Node – Sends a confirmation message back to the user, informing them of the successful booking or cancellation. 🧠 Why This is Useful Managing appointments can be time-consuming.
