Keep database changes easier to understand
When a data source's columns change, create a short reference document that helps collaborators understand the new structure.
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
Convert HTML to PDF
Tool to convert html or a public url into a pdf document. use when you need programmatic pdf generation from html content.
Why this helps
Schema changes can leave people wondering what changed and which fields they should use going forward.
- Create a record of structural changes for later reference.
- Reduce repeated questions after a database changes.
- Make new or renamed properties easier to communicate.
Setup
Build it in a few focused steps.
- 1Connect Notion and Cloudlayer to Notis once through the portal.
- 2Create an automation in the portal or ask Notis conversationally to document data source schema changes.
- 3Describe in one plain-language instruction how to summarize a changed schema into a reference PDF.
- 4Pick the Notion Data Source Schema Updated trigger and choose a channel for run reports.
- 5Test by making a real schema change in a suitable data source and review the PDF.
Questions about this workflow
What changes start the workflow?
The trigger fires on column additions, removals, or renames and includes updated property details.
Will adding a column create many runs?
This schema trigger is intended as a single structural-change signal; it avoids relying on the per-row property updates caused by adding a column.

Supported Triggers and Actions
Notis builds workflows that link Notion to Cloudlayer. A trigger fires from one place; an action lands in another.
Notion triggers
Cloudlayer actions
Recurring trigger
Notis starts this workflow on a schedule, such as daily, weekly, or during business hours.
Add Storage
Tool to add a new user storage configuration. use when you need to attach an external bucket or container for file storage.
Webhook trigger
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Get Asset
Tool to retrieve a specific asset by its id. use when you need to fetch metadata or download url of an existing asset after its generation.
All Page Events
Triggers when any Notion page is created or updated across the workspace.
Get API Status
Tool to test api reachability. use when checking if the cloudlayer api is available.
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.
HTML to Image
Tool to convert base64-encoded html to an image. use when you need to render raw html or a url into png, jpeg, or webp after content load.
New Comment
Triggers when a new comment is added to a specified Notion block or page.
Convert HTML to PDF
Tool to convert html or a public url into a pdf document. use when you need programmatic pdf generation from html content.
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 Assets
Tool to list the ten most recent assets. use when you need to retrieve your latest cloudlayer assets.
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 Storage Configurations
Tool to retrieve a list of all storage configurations. use after authenticating to cloudlayer to view your account's storage settings.
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.
Convert URL to Image
Tool to convert a webpage url to an image. use when dynamic screenshot parameters are needed.
