Check for an existing event before adding a booking
Search for a likely match before creating another appointment from a caller's request.
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
A caller may be rescheduling or confirming a meeting that is already on the calendar, but that context may not be obvious from the call alone.
- Review likely existing matches before booking.
- Reduce duplicate appointments.
- Keep uncertain matches visible for a person to resolve.
Setup
Build it in a few focused steps.
- 1Connect Bland AI and Google Calendar once in the Notis portal.
- 2Create a new automation in the portal or tell Notis to create one.
- 3In one instruction, ask Notis to search for a likely event using the available booking details and report matches before any follow-up action.
- 4Pick a Notis webhook trigger and choose where run reports should go.
- 5Test with one real call example that corresponds to an existing event.
Questions about this workflow
Does finding a match automatically change it?
No. This workflow searches for an event and reports likely matches. It does not change or delete events.
What if the call details are incomplete?
Tell Notis to report that it cannot confidently search when the details needed to identify the meeting are missing.
