Find open calendar slots from a scheduling request
When an API workflow needs a meeting time, have Notis look for available slots in the requested window.
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 time means opening the calendar, comparing busy blocks, and switching back to finish the request.
- Check availability in a specific time range.
- Include event details to make busy intervals easier to understand.
- Reduce back-and-forth between the calendar and the API workflow.
Setup
Build it in a few focused steps.
- 1Connect Apiverve and Google Calendar once in the Notis portal.
- 2In Automations, choose New Automation and name it.
- 3Tell Notis to find free slots for the requested calendar and time range, and summarize suitable options for the scheduling request.
- 4Pick the webhook trigger and choose where run reports should go.
- 5Test with one real request whose time minimum is earlier than its time maximum.
Questions about this workflow
What information must the request include?
Provide the calendars to check and a time range where the minimum precedes the maximum. If omitted, the action defaults to the current UTC day.
Does this book a selected slot?
No. It finds free slots and reports them. Use a separate event creation action to book a time.
Can the result include event context?
The action enhances busy intervals with event details, which Notis can summarize in its run report.
