Book Website Sales Calls with Gemini & Calendly (n8n)

Turn website chats into booked sales calls—automatically

This n8n workflow runs a website booking chatbot that uses Google Gemini (with Groq fallback) to qualify visitors, pulls live availability from Calendly, and books meetings through the Calendly API. Every lead and booking result is logged to Google Sheets and you’re notified via Gmail and a team webhook (Lark).

What this workflow does

• Receives each visitor message through a n8n webhook, including conversation history and the prior state.
• Generates a concise chatbot reply using Google Gemini (Google PaLM API), with a fallback to Groq if Gemini fails or returns empty output.
• Extracts hidden JSON commands from the AI response to decide the next action (e.g., fetch slots, select a time, capture contact/details).
• Fetches available times from Calendly when a visitor agrees to book, then returns three suggested weekday slots in chat.
• Books the meeting via Calendly API after the visitor selects a slot and provides name and email, including confirmation plus reschedule/cancel links.
• Logs results to Google Sheets for booked leads and booking failures.
• Notifies you and your team via Gmail and a Lark webhook.
• Captures lead details (visitor website, or company name + monthly revenue if no website) and updates the booked lead record in Google Sheets, then emails the added details.

Use cases

• SaaS teams that want a Calendly-driven sales call booking assistant inside their website chat.
• Automation engineers building an AI-qualified scheduling flow with n8n.
• Operators who need full lead logging and notifications without manual follow-up.
