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 task deadline can look manageable until meetings and other commitments fill the same stretch of time.
- Review existing events for a proposed deadline window.
- Make planning decisions with fewer calendar surprises.
- Get a concise conflict summary before committing.
Setup
Build it in a few focused steps.
- 1Connect Amazing Marvin and Google Calendar once in the Notis portal.
- 2Create an automation in Automations, New Automation, and give it a name.
- 3Tell Notis to search calendar events for the date range supplied with the webhook and summarize conflicts relevant to the Marvin task, asking for a range if missing.
- 4Pick a webhook as the trigger and choose where run reports should go.
- 5Test with one real task and a date range that includes known calendar events.
Questions about this workflow
Does this determine whether a deadline is achievable?
It can report calendar conflicts, but it cannot know the task's full effort or your capacity unless you provide that information.
What date range should I send?
Provide the start and end of the proposed deadline window so Notis can search the relevant events.
