Validate meeting windows before you commit
Protect focus time by checking conflicts at the moment a request arrives.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
List user busy times
Fetches a user's busy time intervals (internal and external calendar events) in ascending order for a period up to 7 days; keyset pagination is not supported.
Why this helps
Promising a time before checking every calendar creates avoidable rescheduling.
- Catch conflicts early
- Protect deep work blocks
- Give faster scheduling decisions
Setup
Build it in a few focused steps.
- 1Connect Calendly in Notis once and expose a Notis webhook trigger.
- 2Create an automation that checks busy times for the requested user and period.
- 3Choose the webhook as the trigger and copy its endpoint into your intake system.
- 4Select a report channel and test with one real request.
