Every new Notion project gets its own Slack channel automatically
Starting a new project in Notion normally means you (or someone) has to remember to create a matching Slack channel. This automation creates it instantly, so your team has a ready-to-use collaboration space before you finish your first task entry.
Trigger
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.
Action
Create channel
Initiates a public or private channel-based conversation
Why this helps
Scattered projects live in different places: some updates in Slack, some in Notion, some in emails. Neurodivergent founders struggle to maintain this fragmentation and team members waste time searching for where discussions live.
- Every new project starts with a Slack channel ready to go, no manual setup
- Team members know exactly where project discussions happen
- Reduces scattered communication across email, DMs, and half-forgotten channels
- Project structure in Slack mirrors project structure in Notion automatically
Setup
Build it in a few focused steps.
- 1Connect your Notion workspace and Slack account to Notis.
- 2Create an automation with the prompt: 'When I create a new database in Notion, automatically create a Slack channel with the same name in snake-case format and post a link to the database in the new channel.'
- 3Select 'Database Created' as your trigger.
- 4Pick a Slack channel to receive notifications when new project channels are created.
- 5Test by creating a new Notion database and confirm a corresponding Slack channel appears within a minute.
Questions about this workflow
Can I control which databases trigger channel creation?
Yes. Your automation prompt can specify 'only for databases tagged project' or 'only for databases under my teamspace', so personal databases don't get channels.
What naming convention does Slack use for the new channel?
Notis converts the Notion database name to Slack-friendly lowercase with hyphens. For example, 'Client Onboarding' becomes 'client-onboarding'.
Can I automatically invite people to the new channel?
You can ask Notis to also invite your core team to each new project channel by updating your prompt to include that instruction.

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.
