Starts on an incoming request

On a webhook request, validates the collection name, runs MongoDB operations, and returns the result as an HTTP response.

Meetup Participant Registration & Giveaway App

On a form submission, registers meetup participants in Postgres and runs a giveaway, responding via the webhook.

On a webhook request, processes data in code, reads or writes Redis, then branches via switch.

On a webhook call, stores the incoming data in Airtable and caches it in Redis.
