Add event registration entries from incoming webhook signups

Your event signup payloads arrive without a central attendee record, causing coordinators to miss registration context. The sheet builds a consolidated registration list, ready same day.

Overview

Inbound signups often land in developer logs or scattered inboxes, leaving coordinators scrambling to assemble attendee lists. This flow captures every signup into one timestamped registration sheet so program managers can confirm attendance and prepare materials same day.
