Auto-Create Calendar Events From External Tools
Your email parser, Slack bot, or custom tool sends a webhook with an event title and time. Notis parses it and creates a calendar event instantly.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Quick Add Event
Parses natural language text to quickly create a basic google calendar event with its title, date, and time, suitable for simple scheduling; does not support direct attendee addition or recurring events, and `calendar id` must be valid if not 'primary'.
Why this helps
External systems generate scheduling requests (email scheduling plugins, bot commands, etc.) but they never reach your calendar. You have to manually create the events.
- Connect any external tool to your Google Calendar via webhooks
- Automate event creation from scheduling requests in any system
- Reduce manual calendar entry overhead
- Build lightweight calendar integrations without complex middleware
Setup
Build it in a few focused steps.
- 1Connect Google Calendar to Notis.
- 2Create an automation: 'When a webhook arrives with title and time, quick-add the event to my Google Calendar.'
- 3Get the Notis webhook URL and configure your external tool to send requests to it.
- 4Define the expected webhook payload format (title, time, optional description).
- 5Test by sending a test webhook from your external tool and verifying the event appears.
Questions about this workflow
What should the webhook payload include?
At minimum, a title and time. Optional fields: description, duration, attendee emails, calendar name.
Can I use this with multiple external tools?
Yes. Each tool sends its own webhook, and Notis handles all of them the same way.
What timezone does the webhook time use?
Your Google Calendar timezone by default, but you can specify a different timezone in the webhook payload.

Tag Added to Task
Triggers when a tag is added to a task. Note: Asana's event structure is inverted for tag events — the resource is the task and the parent is the tag. So parent.gid gives the tag GID.
Delete event

Task Updated
Triggers when a task is updated in a project.
