Hackathon Participant Badge Generator with QR Code & Email Delivery

Description

A fast, reliable, and fully automated workflow that generates professional participant badges for hackathons, tech events, and workshops — complete with unique Badge ID, QR verification, PDF output, and email delivery.

This workflow takes any simple registration input and transforms it into a verified, branded participant badge in under 10 seconds.

What this workflow does

• Accepts event registrations via a POST Webhook (name, email, event, team, role).

• Performs input validation and disposable/fake email detection using VerifiEmail.

• Creates a unique Badge ID (e.g., HACK-2025-1763560499-AB3XYF).

• Generates a public verification URL and QR code for check-in.

• Builds a high-resolution badge (1056×816px) with event branding, logo, gradient background, and QR code.

• Converts the HTML badge design into a print-ready PDF using PDFMunk (htmlcsstopdf).

• Sends a beautiful HTML email via Gmail that includes:

  • Inline badge preview (visible immediately)
  • Attached PDF badge
  • Verification URL + Badge ID

• Logs all badge metadata to Google Sheets for audit and check-in tracking.

• Returns a clean JSON success response to the caller.
