Create Google Calendar events from an incoming webhook
Your booking form or custom backend knows about a new commitment before you do, and re-typing it into the calendar is the step that gets skipped. Notis takes the webhook and creates the Google Calendar event straight away, so inbound requests become real time on your schedule automatically.
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
Bookings arrive through a form or backend, then wait on a manual copy into the calendar that never happens fast enough.
- Every inbound booking becomes a scheduled event instantly
- No re-typing details from a form into the calendar
- Connects tools that have no native calendar link
- Commitments stop slipping between systems
Setup
Build it in a few focused steps.
- 1Connect Google Calendar to Notis from the portal.
- 2Open Automations, click New Automation, and choose an incoming webhook as the trigger.
- 3Describe the outcome: when this webhook arrives, create a Google Calendar event from the details it carries.
- 4Point your form or backend at the webhook URL Notis gives you and pick the channel for run reports.
- 5Send one test request and confirm the event lands on your calendar.
Questions about this workflow
What tools can send the webhook?
Anything that can make an HTTP request, including form builders, no-code tools, and your own backend.
Do I need to write code to shape the event?
No. Notis reads the incoming data and your plain-language instruction to build the event, no mapping screens involved.
Which calendar receives the event?
Your primary calendar by default, or a named one if you specify it in the prompt.

Supported Triggers and Actions
Notis builds workflows that link Notion to Google Calendar. A trigger fires from one place; an action lands in another.
Notion triggers
Google Calendar actions
All Page Events
Triggers when any Notion page is created or updated across the workspace.
Insert Calendar into List
Inserts an existing calendar into the user's calendar list.
Comment Created
Triggers when a new comment is created in Notion. Optional `page_id` filter scopes to comments on a specific page. When omitted, fires for any new comment in the workspace the integration has access to. Requires the 'Read comments' capability on the Notion integration. If a connection was authorized before that capability was enabled, the user must re-authorize the connection for comment events to flow.
Update Calendar List Entry
Updates an existing entry on the user\'s calendar list.
New Comment
Triggers when a new comment is added to a specified Notion block or page.
Delete Calendar
Deletes a secondary calendar. use calendars.clear for clearing all events on primary calendars.
Database Created
Triggers when a new Notion database (the container) is created. A database is the post-2025-09-03 container that holds one or more data sources. This trigger fires for the container's creation event (`database.created`), distinct from `NOTION_DATASOURCE_CREATED` which fires when a new data source is added to an existing database. Most customers calling Notion's `POST /v1/databases` (the legacy API) or creating a database via the Notion UI will see this event. Adding a new data source to an existing database fires `data_source.created` instead — use `NOTION_DATASOURCE_CREATED` for that. Notion's payload puts `entity.type: "block"` (the container is a `child_database` block in the content tree) and `entity.id` is the database id.
Update Calendar
Updates metadata for a calendar.
Data Source Created
Triggers when a new Notion data source is created. Fires workspace-wide. The payload's `data.parent` carries the data source's tree parent (typically the teamspace) for downstream filtering. A single template-based database creation can fire multiple `data_source.created` events at once — one per data source the template instantiates.
Clear Calendar
Clears a primary calendar. this operation deletes all events associated with the primary calendar of an account.
Data Source Schema Updated
Triggers when a Notion data source's schema is updated. Fires on column add / remove / rename. Payload includes `data.updated_properties: [{id, name, action}]` so consumers can discriminate the kind of change downstream. Optional `data_source_id` filter scopes to schema changes on a single data source. When omitted, fires for any schema change in the workspace the integration has access to. Note: adding a column also fires `page.properties_updated` once per existing row in the data source. Customers wanting a single structural-change signal should use this trigger.
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.
New Page
Triggers when a new page is added to a Notion database.
Delete event
Deletes a specified event by `event id` from a google calendar (`calendar id`); this action is idempotent and raises a 404 error if the event is not found.
Page Added to Page
Fires when a new subpage (a `child_page` type block) is added under a specified parent Notion page.
Create a calendar
Creates a new, empty google calendar with the specified title (summary).
