Consolidate all your tools onto one calendar
Your project management tool, email, and Slack all have updates. Instead of checking four places, every important action lands on your calendar as a structured event via webhook.
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're using 5 different tools (email, Slack, project management, notes, calendar) and nothing talks to each other. You constantly feel behind because information is siloed.
- Consolidate actions from multiple tools into one calendar so you have a single source of truth
- Trigger calendar events from external tools without building custom integrations
- Reduce tool-switching by having all urgent updates land on Calendar
Setup
Build it in a few focused steps.
- 1Connect Google Calendar to Notis
- 2Grab the Notis webhook URL from the automation setup screen
- 3Paste it into your external tool's webhook settings (where you'd normally send alerts)
- 4Test by triggering an action in your other tool and watching the calendar event appear
Questions about this workflow
Which tools can I send webhooks from?
Any tool with webhook support: project management apps, monitoring systems, form submissions, email automation—basically anything that can send an HTTP request.
What should be in the webhook payload?
At minimum: a title and ideally a time. Tell Notis what fields map to calendar event title, description, and date/time.
Can I format the calendar event details?
Yes. You can tell Notis how to format the event from webhook data—for example, 'use the subject line as the title and status as a calendar color'.
