Appointment Booking

Let customers book appointments directly through your AI agent's chat widget.

ChatNexus includes a built-in appointment booking system. Set your weekly availability, define exceptions for holidays or extra hours, and let your website visitors book time slots - all without leaving the chat widget.

Starting a new booking agent? The Appointments & Scheduling template pre-fills the instruction and knowledge base.

Set Weekly Availability

Navigate to your agent's detail page and open the Booking tab. Here you can configure your weekly schedule:

  • Enable or disable each day of the week
  • Set start and end times for each active day
  • Configure appointment duration (e.g., 30 minutes, 1 hour)

Connect Google Calendar (optional)

On the same Calendar & Availability section, click Connect Google Calendar. Once connected:

  • Busy times on your Google Calendar are blocked from booking slots
  • Confirmed ChatNexus bookings are created as Google Calendar events
  • Cancelling or rescheduling updates (or removes) the matching event
💡
Note: This is two-way sync for booking availability and appointments. Customers still get a one-click “Add to Google Calendar” link in their confirmation email. When sync is connected and the event was written, your owner confirmation email omits that button (it is already on your calendar).

Add Date Exceptions

Override your regular schedule for specific dates - useful for holidays, vacations, or extra availability days.

  • Block a date - Mark a normally available day as unavailable
  • Add extra availability - Open up a normally off day with custom hours

💡
Tip: Add public holidays in advance to prevent customers from booking on days your business is closed.

Manage Bookings

View all upcoming bookings in the booking list. Each entry shows:

  • Customer name, email, and phone number
  • Booking date and time slot
  • Booking status (confirmed, rescheduled, cancelled)

Export to Calendar

Each booking can be exported as an ICS file, which you can import into Google Calendar, Outlook, Apple Calendar, or any other calendar application with a single click.

What Visitors See

When a visitor asks to book through your agent's chat widget, the agent can show an in-chat booking calendar with available dates and time slots. No login is required. They'll receive a confirmation email with a link to reschedule or cancel.
