Event signups with tiered tickets, a capacity cap and an automatic waitlist

The scenario takes signups, enforces the capacity cap, builds a tiered PDF ticket via Pdf Generator Api, emails it through Gmail, logs everything in Google Sheets, and notifies the team in Slack.

  • Guests get their ticket automatically — with a code, matched to their tier
  • Capacity is enforced: overflow goes to the waitlist
  • A cancellation immediately promotes the first person in line
  • Organizers see every signup in chat
