Never forget to follow up on blocked work again
Blocked tasks often sit forgotten until a retrospective. This automation watches for blocked status changes in Notion and creates a Slack reminder so you're prompted to unblock it.
Trigger
Page Properties Updated
Triggers when properties of a Notion page are 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 property change in the workspace the integration has access to. Adding a column to a data source fires this trigger once per existing row. Customers can branch on `data.updated_properties` (array of property IDs) to filter downstream.
Action
Create a reminder
Creates a slack reminder with specified text and time; time accepts unix timestamps, seconds from now, or natural language (e.g., 'in 15 minutes', 'every thursday at 2pm').
Why this helps
Neurodivergent founders struggle with task initiation and follow-through. When work is blocked, executive dysfunction makes it easy to avoid the unblocking conversation entirely.
- Reminders appear in Slack automatically, removing the need for you to remember to check
- Reduces the executive dysfunction tax of starting conversations with blockers
- Prevents blockers from silently stalling your entire project
- Keeps your team informed about dependencies they can help resolve
Setup
Build it in a few focused steps.
- 1Connect your Notion and Slack workspaces to Notis.
- 2Create an automation with the prompt: 'When a page property changes to blocked status, create a Slack reminder for me in 2 hours to follow up and unblock it.'
- 3Choose 'Page Properties Updated' as your trigger.
- 4Select which Slack channel should receive reports about when reminders are created.
- 5Test by changing a task status to blocked and verify a reminder appears in Slack within minutes.
Questions about this workflow
Can I customize when the reminder appears?
Yes. Tell Notis in your automation prompt to create the reminder 'in 2 hours', 'tomorrow at 9am', or 'every thursday at 10am'. Notis interprets natural language timing.
Will it create a reminder for every status change, or just blocked?
It triggers only on 'blocked' status changes. Notis filters based on your prompt to avoid reminder spam.
What if I unblock something before the reminder fires?
The reminder will still fire, but you can dismiss it in Slack. You might want to set reminders for only a few hours out if you anticipate fast unblocking.

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.
