Questions, answered
How often does it check registration numbers?
Once per hour by default. You can run it more frequently (every 15 minutes) in the plan if you expect a fast-moving sale.
What triggers an alert?
It fires a Slack message when an event crosses 80% capacity and again when it reaches 100%. Both thresholds are adjustable in the plan.
Can it handle multiple events at once?
Yes. It monitors all your upcoming published Eventbrite events in one run and updates the tracker for each one.
