Check for an existing review before adding another
Send a position update to Notis and have it look for a matching calendar review before deciding whether a new block is needed.
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 alerts about the same position can create duplicate reminders and make an already busy calendar harder to scan.
- Find an existing event that may already cover the review.
- Reduce duplicate calendar blocks from repeated notifications.
- Keep review scheduling tied to the notification details you provide.
Setup
Build it in a few focused steps.
- 1Connect Alpaca and Google Calendar once in the Notis portal.
- 2Create a named automation in Automations, New Automation.
- 3In one instruction, tell Notis to search the calendar for a matching ticker or position review in the provided time range and create an event only if none is found.
- 4Choose the webhook trigger and a report channel.
- 5Send one real notification and check both the search result and any created event.
Questions about this workflow
Can this detect a position change from Alpaca by itself?
No listed Alpaca trigger is available. An external sender must send the position notification and any search time range to the webhook.
What if the notification does not include a time range?
Add a default time range to your instruction or include one in each notification so the calendar search has a defined scope.
