Keep important data signals close to page activity
A Notion page change can prompt Notis to check a relevant ClickHouse signal and return it where you review runs.
Trigger
All Page Events
Triggers when any Notion page is created or updated across the workspace.
Action
Execute ClickHouse Query
Execute a sql query in clickhouse and return the results. this is the primary action for querying data from clickhouse databases.
Why this helps
Frequent dashboard checking breaks focus, while important business signals can be easy to miss between reviews.
- Make a targeted signal easier to notice.
- Reduce repeated dashboard switching.
- Tie useful analytics to active work.
Setup
Build it in a few focused steps.
- 1Connect Notion and ClickHouse to Notis once.
- 2Create an automation in the portal or tell Notis what it should do.
- 3Write one instruction to query a specific relevant ClickHouse indicator after a Notion page event.
- 4Select All Page Events and choose a channel for run reports.
- 5Test with one real page change and ensure the result is focused.
Questions about this workflow
Will every page change be included?
All Page Events covers page creation and updates across the workspace accessible to the integration.
How can I avoid noisy reports?
Keep the instruction focused on a specific signal and the page context that makes it relevant.

Supported Triggers and Actions
Notis builds workflows that link Notion to ClickHouse. A trigger fires from one place; an action lands in another.
Notion triggers
ClickHouse actions
Recurring trigger
Notis starts this workflow on a schedule, such as daily, weekly, or during business hours.
Execute ClickHouse Query
Execute a sql query in clickhouse and return the results. this is the primary action for querying data from clickhouse databases.
Webhook trigger
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Get Database Schema
Get comprehensive schema overview of an entire database including all tables and optionally their column definitions. essential for ai agents to understand the complete database structure in a single call.
All Page Events
Triggers when any Notion page is created or updated across the workspace.
Get Table Schema
Get detailed schema information for a specific table including column definitions, types, keys, and optionally sample data. this is essential for ai agents to understand table structure before constructing queries.
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.
List ClickHouse Databases
List all databases in the clickhouse instance. useful for discovering available databases before querying tables.
New Comment
Triggers when a new comment is added to a specified Notion block or page.
List ClickHouse Tables
List tables in clickhouse databases. returns information about tables including their engine, size, and row count.
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.
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.
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.
