for the curious

You don’t need to read this. Tiny Command auto-maps every field into the visual picker so downstream nodes can pull values by clicking. We show it here for power users who want to know what’s on the wire.

FAQ

Questions about Event Cancelled.

How does the Event Cancelled trigger work in Google Calendar?

Fires when an event is cancelled or deleted from the selected Google Calendar. Use to release Zoom resources, update CRM activity, or notify attendees via another channel.

Is the Event Cancelled trigger real-time?

Yes. Event Cancelled uses webhooks or push subscriptions, not polling. Your workflow fires within seconds of the event happening in Google Calendar.

What data does Event Cancelled return?

The full event payload from Google Calendar. The output shape table on this page lists every field, its type, and an example value so you can map fields into downstream nodes.

Can I filter Event Cancelled so only some events start a workflow?

Yes. Add a Filter node right after the trigger and match on any field, whether that's subject, sender, status, or anything else in the payload. Workflows only continue when the filter passes.

Do I need Google Calendar admin permissions to use Event Cancelled?

For most Google Calendar accounts a standard user can authorize the trigger. Some Google Calendar plans require an admin to enable third-party webhooks. Check Google Calendar's docs if the trigger fails to register.
