Your team sees Notion content updates in Slack the moment they happen
Major updates to important Notion docs deserve announcement, not silent waiting for someone to check. This automation posts when you update page content, so your team catches critical changes instantly.
Trigger
Page Content Updated
Triggers when the body content of a Notion page is updated. Customer optionally scopes with at most one of: - data_source_id: any row in this data source - page_id: this specific page - parent_page_id: any page whose immediate parent is this page With none set, fires for any page content edit in the workspace the integration has access to. Notion aggregates content edits within a short window (~60s typical).
Action
Post message to channel
Deprecated: posts a message to a slack channel, direct message, or private channel. use `send message` instead.
Why this helps
Neurodivergent founders often don't think to announce documentation updates or assume the team will check Notion on their own. Critical process changes or new guidelines get missed entirely.
- Important content changes reach your team immediately in Slack
- No more surprises when a team member discovers an outdated process
- Everyone sees major updates together, reducing confusion and duplicate questions
- Neurodivergent founders don't need to remember to announce; the automation handles it
Setup
Build it in a few focused steps.
- 1Connect Notion and Slack to Notis.
- 2Create an automation with the prompt: 'When the body content of a Notion page I designate as high-importance is updated, post a summary to the team channel saying what changed.'
- 3Select 'Page Content Updated' as your trigger and optionally scope to specific pages or databases.
- 4Choose your team Slack channel for receiving these notifications.
- 5Test by editing content on a key Notion page and verify it posts to Slack.
Questions about this workflow
Won't this spam the channel if I'm constantly editing?
Notion aggregates content edits within about 60 seconds, so minor tweaks don't fire multiple notifications. You can also scope the automation to only important pages to reduce frequency.
Can I see a diff of what changed in the Slack message?
Notis posts the updated content or a summary. For complex diffs, you can adjust your automation prompt to include 'show me what sections changed'.
How do I decide which pages trigger this?
Focus on pages your team needs to know about immediately: onboarding docs, process guides, policies, deadlines, and project scope. Leave out personal notes and drafts.

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.
