Sync Calendar Events as You Confirm Meeting Details
You send a meeting confirmation email with final location or time. Notis finds the related calendar event and updates it immediately. Email and calendar never drift out of sync.
Trigger
Email Sent
Triggers when a Gmail message is sent by the authenticated user. It polls the 'SENT' label and emits metadata including sender, recipients, subject, timestamp, and thread ID.
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
You confirm meeting details via email, but the calendar event still has the old location or time. Later someone joins via Zoom link from the old event details. The event and email become contradictory sources of truth.
- Email and calendar never contradict each other
- Attendees always get the latest details from calendar invites
- Reduces confusion about meeting location or time
- Saves you from manually updating after every confirmation

Questions about this workflow
How does Notis know which calendar event matches the email?
Notis looks for shared attendees, subject line matching, and date info to find the right event.
What if multiple events match the email content?
Notis asks you to confirm which event should be updated so nothing gets changed accidentally.
Can this handle location or attendee changes?
Yes—Notis updates any detail mentioned in your confirmation email including location, time, attendees, or meeting link.
