Check for an existing calendar event before scheduling
Give your team a quick calendar check when an Attio process raises a meeting 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
Repeated requests can lead to duplicate events when nobody remembers whether the meeting was already booked.
- Surface likely matching events before taking another scheduling step.
- Use the event details supplied by the Attio workflow.
- Route a clear search result through Notis run reports.
Setup
Build it in a few focused steps.
- 1Connect Attio and Google Calendar once in the Notis portal.
- 2Create an automation in Automations, New Automation, and name the calendar check.
- 3Describe in one instruction what event details to search for and how to summarize matching results.
- 4Choose the webhook trigger and the channel for run reports.
- 5Test with one real request that has a known matching event in Google Calendar.
Questions about this workflow
Does this automatically prevent duplicates?
No. It finds events using the text query and time ranges supplied to the action. Review the result before creating an event.
What should the Attio process send?
Send a useful text query and, when relevant, a time range. If both time bounds are used, the start bound must not be later than the end bound.
