Find open time for a request sent through Ably
Check specified calendars for free slots before replying to a scheduling request.
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
Comparing calendars by hand adds friction when someone asks for a time that works.
- Check availability across specified calendars
- Return free-slot options for a defined time range
- Reduce manual calendar comparisons
Setup
Build it in a few focused steps.
- 1Connect Ably and Google Calendar once in the Notis portal.
- 2Create an automation in Automations, New Automation, and enter its name and prompt.
- 3Describe in one instruction how to find free slots on the specified calendars for the incoming request's time range.
- 4Pick the webhook trigger and select a run report destination.
- 5Test with one real request that includes a valid time range.
Questions about this workflow
Does this book a slot?
No. Find free slots returns availability and enhanced busy intervals. A separate event creation action would be needed to book a time.
Do the time bounds need to be ordered?
Yes. The time minimum must precede the time maximum when both are provided.
