One-Line Description

Automatically detects missed Zoom demos booked via Calendly and triggers AI-powered follow-up sequences.

Detailed Description

What it does:

When a prospect books a demo through Calendly but fails to join the Zoom meeting, this workflow automatically detects the no-show, generates personalized recovery messages using AI, updates your database, and notifies your sales team—all within minutes of the meeting ending. It bridges Calendly, Zoom, and your follow-up channels to ensure no lead falls through the cracks.

Who it's for:

• Sales teams running high-volume demo calendars who lose 20-40% of booked meetings to no-shows
• Customer success managers conducting onboarding calls where attendance tracking matters
• SDRs and BDRs who need immediate alerts when prospects miss scheduled meetings
• Revenue operations teams seeking to improve demo-to-opportunity conversion rates through faster follow-up

Key Features:

• Real-time no-show detection - Automatically checks Zoom participant lists against expected attendees within seconds of meeting end
• AI-generated recovery messaging - Creates contextual, empathetic follow-up emails and LinkedIn messages tailored to each no-show scenario
• Instant team notifications - Sends formatted Slack alerts with attendee details and suggested next actions so reps can manually follow up if needed
• Attendance tracking database - Maintains a searchable record of all bookings and attendance status for reporting and analysis
• Multi-channel follow-up orchestration - Coordinates email, Slack notifications, and optional CRM updates from a single automation
• Selective event filtering - Processes only specific Calendly event types so you control which meetings trigger the workflow

How it works:

1. Booking capture: Calendly webhook fires when a demo is scheduled, extracting Zoom meeting details and attendee information
2. Meeting monitoring: When the Zoom meeting ends, a second webhook triggers attendance verification by pulling the participant list from Zoom's API
3. No-show identification: Workflow cross-references the expected attendee email with actual Zoom participants to confirm whether they attended
4. Automated response: For confirmed no-shows, AI generates personalized recovery messages while the system updates your database and notifies your team via Slack
5. Optional integrations: Simultaneously updates CRM deal stages or triggers additional follow-up sequences based on your configuration

Setup Requirements

Prerequisites:

• Calendly account (any paid plan) with webhook access and Personal Access Token
• Zoom account (Pro or higher) with Server-to-Server OAuth app credentials for API access
• OpenAI API key for AI-generated follow-up message creation
• Slack workspace with OAuth permissions to post messages (optional but recommended)
• n8n Data Table created with columns: meeting_id, email, status (built-in n8n feature, no external database needed)
• Email sending service configured in n8n (SMTP, Gmail, SendGrid, etc.) if enabling automated email sending
• CRM API access (HubSpot, Salesforce, Pipedrive, etc.) if enabling deal updates (optional)

Note: Zoom API has rate limits (varies by plan); this workflow makes 1-2 API calls per meeting end event.

Estimated Setup Time:

45-60 minutes including Zoom app creation, Calendly webhook configuration, and Data Table setup

Installation Notes

Critical setup steps:

• Zoom webhook validation: You must complete Zoom's webhook endpoint validation process before receiving real events. The workflow includes a dedicated validation path—run it once after creating your Zoom app.
• Calendly webhook creation: Use the "Manual Setup Trigger" path in the workflow to programmatically create your Calendly webhook subscription. This only needs to run once.
• Event type filtering: Replace the placeholder YOUR_CALENDLY_EVENT_TYPE_URI with your specific demo event type URI from Calendly to avoid processing all meeting types.
• Test with a real meeting: Book a test demo, join briefly with a different email than the booking email, then leave. The workflow should detect the "no-show" for the booking email.

Common pitfalls to avoid:

• Forgetting to enable the disabled "Send Recovery Email" node after testing (it's disabled by default to prevent accidental sends during setup)
• Not configuring Zoom Server-to-Server OAuth correctly (requires Account ID, Client ID, and Client Secret—not JWT credentials)
• Using a personal Calendly account instead of an organization account (webhooks require organization-level access)
• Overlooking the Data Table creation step—the workflow will fail without this internal database

Testing recommendations:

• Start with Slack notifications only (leave email sending disabled) to verify the workflow logic
• Use your own email as a test booking to safely generate AI messages without sending to real prospects
• Check the Data Table after each test to confirm booking records are being created and updated correctly

Customization Options

Easy modifications:

• Swap email for SMS: Replace the email node with Twilio SMS to send text message follow-ups instead
• Add delays: Insert "Wait" nodes to schedule follow-ups hours or days later rather than immediately
• Change AI tone: Modify the OpenAI prompt to match your brand voice (casual, formal, humorous, etc.)
• Multi-step sequences: Duplicate the AI and email nodes to create a 3-touch follow-up cadence over several days
• Different CRM platforms: The HubSpot node can be swapped for Salesforce, Pipedrive, or any CRM n8n supports

Extension possibilities:

• Add Google Sheets logging for executive dashboard reporting on no-show rates
• Integrate with Calendly's rescheduling API to automatically send rebooking links
• Connect to Loom or Vidyard APIs to attach pre-recorded demo videos in follow-up emails
• Create a "second chance" discount workflow that offers incentives for rescheduling
• Build a predictive model by exporting no-show data to analyze patterns (time of day, lead source, etc.)

Use Case Examples

• SaaS sales team: A B2B software company runs 40+ demos per week. When prospects no-show, this workflow immediately notifies the assigned rep in Slack with a pre-written LinkedIn message, sends an empathetic recovery email offering a Loom recording alternative, and flags the deal in HubSpot for manual outreach within 2 hours.

• Agency onboarding: A marketing agency conducts discovery calls with new clients. If a client misses their scheduled kickoff meeting, the workflow logs the no-show, updates the client status in their CRM, and sends a friendly rescheduling email with three alternative time slots—all before the account manager even notices.

• Customer success: A customer onboarding team tracks training session attendance. When users don't join their scheduled implementation calls, the workflow automatically sends a resource-rich email with documentation links, notifies the CSM team channel, and schedules a follow-up task in their project management tool.
