Confirm Cal bookings from Trello approvals
Mark the approval in Trello and let Notis finalize the pending Cal booking.
Trigger
Card Updated Trigger
Triggered when a specific card is updated
Action
Confirm booking by uid
Confirms an existing booking by `bookinguid` if the booking exists and is in a state allowing confirmation (e.g., not already cancelled or confirmed); this finalizes the booking, does not modify its details, and should typically be performed once.
Why this helps
Approved meetings remain pending while someone manually confirms them.
- Speeds confirmation
- Makes approval status actionable
- Reduces manual calendar administration

- 1Connect Trello and Cal once.
- 2Create an automation telling Notis to confirm the booking when an approval update is detected.
- 3Pick Trello Card Updated Trigger.
- 4Choose reports and test with one pending booking.
Questions about this workflow
