Trigger
Event Canceled or Deleted
Triggers when a Google Calendar event is cancelled or deleted. Returns minimal data: event_id, summary (if available), and cancellation timestamp.
Action
Convert HTML to PNG
Tool to convert HTML string to PNG image. Use when you need a PNG from HTML after preparing your markup.
Why this helps
A cancellation can disappear into a busy calendar, leaving plans and reminders out of date.
- Highlight the event summary when it is available.
- Include the cancellation timestamp returned by the trigger.
- Create a visual record that is easy to review.
Setup
Build it in a few focused steps.
- 1Connect Google Calendar and CustomJS once in the Notis portal.
- 2Create an automation and describe the result in plain language.
- 3Ask Notis to render the available event ID, summary if present, and cancellation timestamp as a clear HTML notice and convert it to PNG.
- 4Pick Event Canceled or Deleted as the trigger and select a report channel.
- 5Test with one real cancellation and inspect the notice.
Questions about this workflow
Will the notice always include the event summary?
No. The cancellation trigger returns the summary only if available.
Does this restore a deleted event or update other plans?
No. This workflow creates an image notice from the minimal cancellation data returned by the trigger.
