Check the new Appointo time when a calendar event changes
A time change is easier to manage when you know whether the new slot is bookable.
Trigger
Event Updated
Triggers when an existing Google Calendar event is modified. Returns the event ID, change type, and the specific fields that changed with their previous and new values.
Action
Get Appointment Availability
Tool to get calendar availability for a specific appointment. Use when you need to fetch available time slots for an appointment within a date range.
Why this helps
Moving a calendar event does not establish that the appointment system can accept the new time.
- Use the changed event fields to focus the availability check on the revised time.
- See a potential scheduling conflict before updating customer expectations.
- Keep the next step visible when the appointment identity is unclear.
Setup
Build it in a few focused steps.
- 1Connect Google Calendar and Appointo once in the Notis portal.
- 2Create an automation in Automations, New Automation, and give it a clear name.
- 3Tell Notis to identify the relevant Appointo appointment, check availability for the event's new time, and report the result with the previous and new event details.
- 4Pick the Google Calendar Event Updated trigger.
- 5Choose where run reports go, then test with one real event time change.
Questions about this workflow
Does this reschedule the Appointo booking too?
No. This workflow checks availability for the changed time. Rescheduling is a separate Appointo action and should follow a confirmed available slot.
What does the workflow use to find the appointment?
Notis can use the event details available in the trigger. Include a clear appointment reference in the event when the title or other context is not enough.
