Turn external system webhooks into calendar events
When an external tool or custom backend sends a webhook to Notis, it automatically creates a calendar event with the right timing and details—no manual sync needed.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Create Event
Creates an event on a google calendar, needing rfc3339 utc start/end times (end after start) and write access to the calendar. by default, adds the organizer as an attendee unless exclude organizer is set to true.
Why this helps
Neurodivergent founders often run disparate tools that don't talk to each other. Events that exist in project management, CRM, or custom systems never make it to the calendar because manual sync feels insurmountable.
- Sync events from any tool that can send webhooks—your own systems, less-common apps, custom backends
- Stop manually creating calendar entries for external tool updates
- Your calendar becomes a unified source of truth across your entire toolstack
Setup
Build it in a few focused steps.
- 1Connect Google Calendar to Notis.
- 2Tell Notis: 'When you receive a webhook with event information, create a calendar event with those details.'
- 3Notis will generate a unique webhook URL for you.
- 4Configure your external system or tool to send webhooks to that URL (Notis will guide the format).
- 5Test by triggering a webhook from your external system and verifying the calendar event appears.
Questions about this workflow
What format should the webhook payload be?
Notis accepts common formats (JSON with title, date, time fields). Tell Notis your payload structure, and it maps it automatically.
Can I create different event types from different webhooks?
Yes. Set up multiple automations for different webhook sources—e.g., sales pipeline updates create one type of event, project milestones create another.
What if my external system changes its webhook format?
Tell Notis the new structure, and it updates the mapping. No code changes needed.
