Check for an existing event before scheduling
Give Notis a scheduling request through Ably and have it search the calendar for a likely match.
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
Without a quick calendar check, a request can lead to duplicate events or unnecessary follow-up.
- Check for a likely existing event before further scheduling
- Use request text and time range in the search
- Make follow-up decisions with calendar results in view
Setup
Build it in a few focused steps.
- 1Connect Ably and Google Calendar once in the Notis portal.
- 2Create an automation in Automations, New Automation, and provide a name and prompt.
- 3In one instruction, ask Notis to search the specified calendar for an event matching the request text and time range, then report likely matches.
- 4Pick the webhook trigger and choose where run reports should go.
- 5Test with one request for an event that is already on the calendar.
Questions about this workflow
Does this create or change calendar events?
No. Find event searches a specified calendar using a text query and optional time ranges. This workflow reports matches for review.
What if I provide both time bounds?
Ensure the start bound, timemin, is not chronologically after timemax.
