New Notion tasks automatically add your team to the right Slack channel
When a new task is created in Notion, you have to remember to invite everyone to the Slack channel. This automation adds your team instantly, so the conversation is ready to go before anyone even opens Notion.
Trigger
Page Created
Triggers when a new Notion page is created. Customer optionally scopes with at most one of: - data_source_id: new row in this data source - parent_page_id: new sub-page under this page (immediate parent only) With neither set, fires for any new page in the workspace the integration has access to. Notion sends ~60s aggregation latency on most events.
Action
Invite users to a Slack channel
Invites users to an existing slack channel using their valid slack user ids.
Why this helps
Scattered communication across Notion and Slack means some team members miss conversations entirely. Manually inviting people is easy to forget, leading to duplicated discussions in DMs.
- Team members are in the Slack channel before they even know a new task exists
- Reduces friction for cross-functional work by pre-seeding the conversation space
- Prevents team members from being left out of important task discussions
- Creates a single channel where task discussions happen naturally
Setup
Build it in a few focused steps.
- 1Connect your Notion and Slack account to Notis.
- 2Create an automation with the prompt: 'When a new task is created in my Task database, invite the engineering team and design team to the corresponding project Slack channel.'
- 3Select 'Page Created' as your trigger and scope to your tasks database.
- 4Specify which Slack channel people should be invited to.
- 5Test by creating a new Notion task and confirming team members are automatically added to the Slack channel.
Questions about this workflow
What if some people are already in the channel?
Slack ignores invite attempts for people already in the channel, so it's safe to invite the whole team even if some are already members.
Can I invite different teams based on the task type?
Yes. Your automation prompt can say 'if task type is design, invite the design team; if engineering, invite the engineering team'.
How do I specify which people constitute 'the team'?
You can reference a Slack user group (like @engineering-team or @design-team) in your prompt, and Notis will invite all members.

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.
