What it does

This AI-powered voice agent automates appointment scheduling for dental practices by processing incoming webhook requests containing patient interaction data. It uses Google Gemini to analyze patient needs, checks real-time availability via Google Calendar, and books confirmed slots while logging details like name and insurance to Google Sheets. The system maintains conversation context to handle natural dialogue flows and offers alternative time slots if the preferred time is unavailable.

Watch out for

Timezone mismatches between the webhook payload and Google Calendar can cause double bookings so always normalize timestamps to UTC before checking availability.
Google Sheets API quotas may throttle rapid batch writes during peak hours so implement a small delay or queue mechanism before logging entries.
PII data like insurance numbers might be logged in plain text if not sanitized by the LLM prompt so add explicit instructions to mask sensitive fields.
Calendar conflicts can arise from overlapping events if the agent does not check for buffer times between appointments so enforce a minimum gap in your availability logic.
