Find available calendar slots from Celigo requests
Have Notis check availability when an integration sends a scheduling request, then report the open slots.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Find free slots
Finds free/busy time slots in google calendars for specified calendars within a defined time range (defaults to the current day utc if `time min`/`time max` are omitted), enhancing busy intervals with event details; `time min` must precede `time max` if both are provided.
Why this helps
Finding a workable meeting time can mean checking several calendars and repeating the same availability search.
- Check selected calendars in a single request.
- Use a defined time range to keep availability results relevant.
- Give the next scheduling step a clear view of open slots.
Setup
Build it in a few focused steps.
- 1Connect Celigo and Google Calendar once in the Notis portal.
- 2Create an automation in Automations, New Automation, and give it a name.
- 3Tell Notis in one instruction to find free slots on the specified calendars for the request's time range and summarize the results.
- 4Choose a webhook trigger and where run reports should go.
- 5Test with one real request whose time min precedes time max.
Questions about this workflow
Can the request include multiple calendars?
Yes. The action accepts specified calendars, subject to access for the connected account.
What happens if no time range is supplied?
The action defaults to the current UTC day. Supplying a range usually makes the result more useful.
Does this reserve an available slot?
No. It finds free slots. Creating an event is a separate action and requires event details and write access.
