Sync Any Tool Into Your Google Calendar
Your project management tool, CRM, or custom system can trigger calendar events automatically via webhook. A new sales call is scheduled in your CRM? Notis creates the calendar event instantly, keeping everything in sync.
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
You use a specialized tool for client calls or project work, but it doesn't talk to Google Calendar. You have to manually create calendar invites for each event, or people miss calendar notifications.
- Eliminate manual calendar entry for events created elsewhere
- Tools stay in sync without manual updates
- Calendars reflect your actual commitments across all systems
- Reduce missing calendar invites from external tools
Setup
Build it in a few focused steps.
- 1Connect Google Calendar to Notis
- 2Create automation: 'When I receive a webhook from my CRM (or tool name), extract the meeting details and create a calendar event with the attendees and time specified'
- 3Set trigger to 'Webhook' and get your unique webhook URL from the automation settings
- 4Paste the webhook URL into your external tool's settings so it sends data to Notis
Questions about this workflow
What information should the webhook send?
At minimum: event title, date, time, and attendee email. Any other details (location, description) are optional.
Does this work with tools that don't have native integrations?
Yes—any tool that can send an HTTP request can use webhooks to trigger Notis automations.
Can I modify the event details before it gets created?
Yes, Notis can transform the incoming data—rename fields, add descriptions, set up recurrence, etc.
