Check Calendar Availability from Apilio
Get a clear view of open slots for the time range you asked about.
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
Checking calendars one by one interrupts focused work and slows down decisions.
- Check availability across specified calendars
- Make scheduling decisions with less tab switching
- Use the requested time range
Setup
Build it in a few focused steps.
- 1Connect Apilio and Google Calendar once in the Notis portal.
- 2Create an automation in Automations, New Automation, and give it a name.
- 3Tell Notis to find free slots for the calendars and time range named in the request, ensuring the start precedes the end.
- 4Choose the webhook trigger and a report channel, then test with one real availability request.
Questions about this workflow
What does the request need to specify?
Name the calendars and a time range. The start time must come before the end time.
What if I omit the time range?
The action defaults to the current UTC day, so include a range when you need another period.
