Track Notion schema changes in Knack
When a Notion data source structure changes, let Notis update the workspace register so the change is not another thing to remember.
Trigger
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.
Action
Update object record
Tool to update an existing record in a specific Knack object. Use when you need to modify field values in an existing record. Only fields provided in the request will be updated; all other fields remain unchanged.
Why this helps
Changes to database structure can affect routines and workflows, but are easy to overlook across a growing workspace.
- Keep structural changes visible in an operational register.
- Reduce manual workspace audits.
- Make downstream workflow maintenance easier to plan.
Setup
Build it in a few focused steps.
- 1Connect Notion and Knack to Notis once through the portal.
- 2Create an automation in the portal or tell Notis what you want conversationally.
- 3Ask Notis in one instruction to update the corresponding Knack register when a Notion data source schema changes.
- 4Select Data Source Schema Updated and choose a channel for run reports.
- 5Rename or add one test property and verify the Knack register update.
Questions about this workflow
What changes does this event cover?
It fires when a data source schema changes, such as a column being added, removed, or renamed.
Can the workflow be scoped?
The trigger supports an optional data_source_id filter; select the relevant data source when configuring it.

Supported Triggers and Actions
Notis builds workflows that link Notion to Knack. A trigger fires from one place; an action lands in another.
Notion triggers
Knack actions
Recurring trigger
Notis starts this workflow on a schedule, such as daily, weekly, or during business hours.
Create object record
Tool to create a new record in a specific Knack object. Use when you need to add new data to a Knack database object. Requires object-based API key authentication.
Webhook trigger
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Create View Record
Tool to create a new record through a form view in Knack. Use when you need to add a record to a Knack object using a form view interface. Only fields that exist in the form will be used, and any record rules configured on the form will be triggered.
All Page Events
Triggers when any Notion page is created or updated across the workspace.
Delete Object Record
Tool to delete a single record from a specific Knack object by its ID. Use when you need to permanently remove a record from an object. This action is permanent and cannot be undone. Requires API key authentication (X-Knack-Application-Id and X-Knack-REST-API-KEY headers).
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.
Delete View Record
Tool to delete a record through a view that contains a delete link. Works with tables, lists, searches, calendars, and details views. This operation is permanent and cannot be undone. Use only after confirming the correct scene_key, view_key, and record_id.
New Comment
Triggers when a new comment is added to a specified Notion block or page.
Get Object Record
Tool to retrieve a single record by its ID from a specific Knack object. Returns the complete record with all field values in both formatted and raw formats. Use this for object-based access which requires API key authentication.
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.
List Object Records
Tool to retrieve multiple records from a specific Knack object (table). Returns up to 1000 records per page with pagination support. Use this for object-based access which requires API key authentication and provides full access to all fields and records. Supports filtering by field values and sorting by field keys.
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.
List View Records
Tool to retrieve multiple records from a specific Knack view (tables, lists, searches, calendars). Use when you need to fetch data from a view with pagination support. Returns only fields included in the view configuration.
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.
Update object record
Tool to update an existing record in a specific Knack object. Use when you need to modify field values in an existing record. Only fields provided in the request will be updated; all other fields remain unchanged.
