Find open meeting times from Basin requests
When someone submits a meeting request, Notis can check for free slots in the time range you specify and report options to consider.
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 that works means bouncing between a request and calendar availability, often while trying to hold onto the rest of your day.
- Check calendar availability in the context of a submitted request.
- Reduce manual free and busy checking.
- Get candidate slots to review before making a commitment.
Setup
Build it in a few focused steps.
- 1Connect Basin and Google Calendar once in the Notis portal.
- 2Create an automation in Automations, New Automation, and give it a name.
- 3In one instruction, tell Notis to find free slots in the request's stated date range and report candidate times for review.
- 4Pick the webhook trigger and choose where run reports should go.
- 5Test with one real meeting request that includes a usable time range.
Questions about this workflow
Does this automatically book a free slot?
No. It finds candidate slots and reports them. A separate step is needed to create an event after a time is agreed.
What if the request does not include a time range?
Have the instruction ask Notis to flag missing date or range details rather than search an arbitrary window.
Can it check more than one calendar?
The action supports specified calendars. Name the calendars to check in your instruction, and ensure the connected account can access them.
