Overview

Event Registration + Auto-Enrichment Intelligence

Who is this for? Event organizers, conference planners, and marketing teams fighting registration drop-off who want 4-field forms with LinkedIn-level attendee intelligence.


What problem is this workflow solving? Multi-page forms kill conversions:

  • 80-90% drop-off on page 2
  • No attendee insights post-reg
  • Manual enrichment wastes hours
  • Abandoned carts = lost revenue

This captures 4 fields but enriches 15+ data points automatically.


What this workflow does

3 Webhook Intelligence Suite:

  • POST /event-registration: 4-field form → enrichment → HubSpot
  • POST /reg-beacon: Abandoned cart tracking pixel
  • POST /validate-promo: AJAX promo code validation

Requires 2 sub-workflows:

  1. Abandoned Cart Recovery
  2. Participant Re-engager

Enrichment Waterfall: Clearbit → LinkedIn (Proxycurl) → Google+AI → Full profile

Outputs:

  • HubSpot contacts with company/role/title
  • Data Tables: enriched_profiles / reg_analytics
  • Slack alerts + email confirmations

Setup (12 minutes)

  • Data Tables: enriched_profiles, reg_analytics, promo_codes
  • HubSpot: API key + custom properties
  • APIs: Clearbit, Proxycurl, SerpAPI, Gemini
  • Host: reg-page/index.html (update webhook URLs)
  • SMTP/Slack: Notifications

Fully configurable, no code changes needed.


How to customize to your needs

  • Forms: Swap HTML for Typeform/Webflow
  • Enrichment: Add Apollo/Hunter for emails
  • CRM: HubSpot → Salesforce → Airtable
  • Promos: Tiered discounts / early-bird
  • Companion: Abandoned Cart + Re-engager templates

ROI:

  • 3x registration completion (4 fields vs 12+)
  • 65% enriched profiles (company/role/title)
  • 20% revenue recovery (abandoned carts)
