Keep Calendar Events Current as Details Evolve
Someone emails you the Zoom link for tomorrow's call. Notis finds the related calendar event and patches it in automatically. Same for location changes, agenda additions, or attendee updates. Your calendar always has the latest details.
Trigger
New Gmail Message Received Trigger
Triggers when a new message is received in Gmail.
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
Details get sent via email but the calendar event has outdated info. You have to manually update the event each time something changes. Attendees end up with wrong links or locations.
- Calendar events stay current as details change
- Attendees always get correct links and locations
- Reduce manual calendar updates
- Email and calendar stay synchronized
Setup
Build it in a few focused steps.
- 1Connect Gmail and Google Calendar to Notis
- 2Create automation: 'When I receive an email with new details for a scheduled meeting (like a Zoom link, location change, or agenda update), find the related calendar event and update it'
- 3Set trigger to 'New Email Received' and choose your channel
- 4Test by sending an email with meeting details—Notis will update the related event
Questions about this workflow
What kinds of details can Notis update?
Zoom links, meeting location, description, agenda, attendees, or any other event field mentioned in the email.
Will Notis overwrite my custom notes?
No, Notis only updates fields explicitly mentioned in the email, preserving your notes.
What if the email updates conflict with the calendar?
Notis asks you to confirm before patching to prevent accidental overwrites.
