Let calendar context reflect completed work
Marking a task done can also keep the event that tracks it from looking unfinished.
Trigger
Task Details Changed
Triggers when a specific task's details change. This trigger monitors a single Google Task and fires when any of its details (title, notes, status, due date, completion, position) are modified.
Action
Patch Event
Updates specified fields of an existing event in a google calendar using patch semantics (array fields like `attendees` are fully replaced if provided); ensure the `calendar id` and `event id` are valid and the user has write access to the calendar.
Why this helps
Completed work can still appear open in a calendar entry, creating uncertainty during reviews.
- Make completed work easier to recognize in calendar reviews.
- Reduce uncertainty about whether a scheduled task happened.
- Keep task and event context aligned.
Setup
Build it in a few focused steps.
- 1Connect Google Tasks and Google Calendar once in the Notis portal.
- 2Create an automation in Automations, then choose New Automation.
- 3Tell Notis how to identify the related event and what completion detail to add when the task is completed.
- 4Pick the Google Tasks Task Details Changed trigger and choose where run reports should go.
- 5Test with one real completed task and its matching event.
Questions about this workflow
Will it delete or cancel the calendar event?
No. This workflow updates a matching event with completion context. Tell Notis to skip changes if it cannot confidently identify one.
What if a task is reopened?
You can instruct Notis to remove or revise the completion note when the task becomes incomplete, if that behavior is wanted.
