Track Notion page updates with Slack message stars
Notion pages contain multiple blocks and updates happen constantly. This automation stars a related Slack message each time a block is updated, giving you a visual heartbeat of page activity that's impossible to ignore.
Trigger
Page Updated
Triggers when any block within a specified Notion page is updated.
Action
Add a star to an item
Stars a channel, file, file comment, or a specific message in slack.
Why this helps
Neurodivergent founders lose track of whether pages are being actively maintained or gathering dust. Silent updates in Notion leave uncertainty about project health.
- At a glance, you see which Notion pages are receiving attention and which are abandoned
- No need to hunt through version history; stars accumulate as updates happen
- Creates a satisfying visual that celebrates active work and surfaces stagnant pages
- Team sees page vitality without context-switching to Notion
Setup
Build it in a few focused steps.
- 1Connect your Notion workspace and Slack account to Notis.
- 2Create an automation with the prompt: 'When any block within my main project page is updated, star the pinned project status message in the main channel.'
- 3Select 'Page Updated' as your trigger and scope to specific pages.
- 4Pin a message in your Slack channel that will collect stars.
- 5Test by editing any block (text, a database, an image, etc.) in a Notion page and verify a star appears on the pinned message.
Questions about this workflow
What counts as a 'block' in Notion?
Everything: text edits, property changes, embedded database updates, file uploads, anything within the page. Very sensitive, so consider scoping narrowly if it feels too noisy.
Can I star different messages based on which page is updated?
Yes. Create separate automations for different pages or use branching logic to star different messages based on which page updated.
What if the same message gets starred a thousand times?
Slack allows unlimited stars on a single message, so it just accumulates. Rotate to a new pinned message monthly for a fresh count.

Supported Triggers and Actions
Notis builds workflows that link Notion to Slack. A trigger fires from one place; an action lands in another.
Notion triggers
Slack actions
All Page Events
Triggers when any Notion page is created or updated across the workspace.
Set snooze duration
Deprecated: turns on do not disturb mode for the current user, or changes its duration. use `set dnd duration` instead.
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.
Add a custom emoji to a Slack team
Deprecated: adds a custom emoji to a slack workspace given a unique name and an image url. use `add emoji` instead.
New Comment
Triggers when a new comment is added to a specified Notion block or page.
Add an emoji alias
Adds an alias for an existing custom emoji in a slack enterprise grid organization.
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.
Add a remote file
Adds a reference to an external file (e.g., google drive, dropbox) to slack for discovery and sharing, requiring a unique `external id` and an `external url` accessible by slack.
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.
Add a star to an item
Stars a channel, file, file comment, or a specific message in slack.
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.
Add call participants
Registers new participants added to a slack call.
New Page
Triggers when a new page is added to a Notion database.
Add emoji
Adds a custom emoji to a slack workspace given a unique name and an image url; subject to workspace emoji limits.
Page Added to Page
Fires when a new subpage (a `child_page` type block) is added under a specified parent Notion page.
Add reaction to message
Adds a specified emoji reaction to an existing message in a slack channel, identified by its timestamp; does not remove or retrieve reactions.
