Generate Smart Calendly Notifications for Outlook and Slack using GPT-4

This n8n automation notifies you whenever someone books a meeting with you via Calendly. It sends a customized email via Outlook and a Slack message using details from the event.

📌 What This Workflow Does

1. Listens for new Calendly meeting bookings (invitee.created).
2. Extracts key details (name, email, reason for meeting, start time).
3. Uses an AI agent to generate both:
   • A HTML email sent to you via Outlook.
   • A Slack message sent to your chosen channel.

⚙️ Step-by-Step Setup Instructions

1. 🔗 Calendly API Setup

• In n8n: Go to Credentials → Add Credential → Calendly API.
• Connect your account with the personal access token.
• In the Calendly Trigger node, set event to invitee.created.

2. 📧 Microsoft Outlook Credential

• Add Microsoft Outlook credentials via OAuth2 in n8n → Credentials.
