Start each week with a synced, up-to-date calendar
Every Monday at 6am, Notis checks that all your calendars are properly connected and synced to Google Calendar. You start the week knowing nothing's missing or broken.
Trigger
Recurring schedule
Notis starts this workflow on a schedule, such as daily, weekly, or during business hours.
Action
List Google Calendars
Retrieves calendars from the user's google calendar list, with options for pagination and filtering.
Why this helps
You have multiple calendars (work, personal, client) but sometimes they don't sync properly. You miss an event because it was on a calendar that wasn't showing up.
- Start each week knowing all your calendars are properly synced
- Catch calendar sync failures early instead of discovering them mid-week
- Reduce anxiety about missing events due to integration issues
Setup
Build it in a few focused steps.
- 1Connect all your calendars to Notis (work, personal, etc.)
- 2Tell Notis: 'Every Monday at 6am, verify all my calendars are synced to Google Calendar'
- 3Notis will run the sync and report results in your chosen Slack channel
- 4Monitor the weekly reports to ensure everything stays connected
Questions about this workflow
What if a calendar isn't syncing?
Notis will alert you and provide instructions to re-authenticate that calendar connection.
Will this affect my events?
No. It's a verification check only—it doesn't create, modify, or delete events.
Can I run it more often than weekly?
Yes. You can ask for daily, twice-weekly, or on-demand syncs.
