Check Hookdeck transformations when Notion's schema changes
When your Notion data structure changes, make it easier to remember the webhook transformations that may deserve a review.
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
Get transformations
Tool to list Hookdeck transformations. Use when you need to retrieve or filter your Hookdeck transformations.
Why this helps
A renamed or removed Notion property can leave related payload assumptions out of sight across tools.
- Make structural changes visible to the people maintaining event flows.
- Retrieve the transformation list as a starting point for review.
- Reduce the chance that schema work and webhook maintenance drift apart.
Setup
Build it in a few focused steps.
- 1Connect Notion and Hookdeck to Notis once in the portal.
- 2Create an automation through the portal or by asking Notis conversationally.
- 3In one instruction, ask Notis to list Hookdeck transformations for review when a Notion data-source schema changes.
- 4Choose Data Source Schema Updated, select a report channel, and test with a real schema change.
Questions about this workflow
Does this edit transformations automatically?
No. It lists transformations for review; changes should follow your normal validation process.
Can the trigger distinguish what changed?
The event includes updated-property details, which Notis can consider when following an instruction about schema changes.

Supported Triggers and Actions
Notis builds workflows that link Notion to Hookdeck. A trigger fires from one place; an action lands in another.
Notion triggers
Hookdeck actions
Recurring trigger
Notis starts this workflow on a schedule, such as daily, weekly, or during business hours.
Bulk Cancel Hookdeck Events
Tool to create a bulk cancellation job for events. Use when you need to cancel multiple events matching filters.
Webhook trigger
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Bulk Retry Hookdeck Events
Tool to initiate a bulk retry for a set of events. Use when you need to retry multiple failed events matching filters.
All Page Events
Triggers when any Notion page is created or updated across the workspace.
Cancel Hookdeck Event
Tool to cancel all future delivery attempts for a specific event. Use when you need to stop retries of an event before manual intervention.
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.
Cancel Hookdeck Scheduled Retries
Tool to cancel all future scheduled retries for an event. Use when you need to mute automatic retry attempts after repeated failures.
New Comment
Triggers when a new comment is added to a specified Notion block or page.
Create Hookdeck Bookmark
Tool to create a new bookmark. Use when you want to bookmark a specific event for quick access.
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.
Create Hookdeck Connection
Tool to create a connection between a source and a destination. Use after setting up or referencing source/destination.
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.
Create Hookdeck Destination
Tool to create a new Hookdeck destination. Use after setting up sources when you need to route events to endpoints.
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.
Create Hookdeck Source
Tool to create a new Hookdeck source. Use after setting up your project when you need to receive and route incoming webhooks.
