Check your calendar before you confirm a callback time
Search the requested window for relevant events before you promise a caller a time that may already be taken.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Find event
Finds events in a specified google calendar using text query, time ranges (event start/end, last modification), and event types; ensure `timemin` is not chronologically after `timemax` if both are provided.
Why this helps
Agreeing to a callback before checking the calendar creates avoidable rescheduling.
- Review relevant events before replying to a caller.
- Search within the time range provided by the webhook.
- Avoid committing to a callback without checking first.
Setup
Build it in a few focused steps.
- 1Connect Callerapi and Google Calendar once in the Notis portal.
- 2Create an automation in Automations, New Automation, and give it a name and prompt.
- 3Tell Notis to search the specified calendar and time window, then summarize relevant events for your decision.
- 4Pick the webhook trigger and choose where run reports should go.
- 5Test with one real example containing a calendar and valid time range.
Questions about this workflow
Does this reserve the requested time?
No. Find event searches for matching events; it does not reserve time. Use Find free slots to check availability.
Can Notis search without a time range?
The action supports text and time filters. Provide a useful time window in the webhook request for a focused search.
