Clear cancelled trading reviews from your calendar
When a review is cancelled, send its event details to Notis so the obsolete block can be removed.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Delete event
Deletes a specified event by `event id` from a google calendar (`calendar id`); this action is idempotent and raises a 404 error if the event is not found.
Why this helps
Cancelled reviews that remain on the calendar create clutter and can lead to unnecessary context switching.
- Remove a specific cancelled review event.
- Keep calendar follow-up aligned with current plans.
- Use the event identifiers supplied by the cancellation notice.
Setup
Build it in a few focused steps.
- 1Connect Alpaca and Google Calendar once in the Notis portal.
- 2Create an automation in Automations, New Automation, and describe the cancellation outcome.
- 3Tell Notis to delete the specified review event using the calendar ID and event ID from the notification.
- 4Choose the webhook trigger and where run reports should go.
- 5Test with a real cancellation for a test event and confirm it is gone.
