Auto-Document Schema Changes for Your Team

Added a column? Removed a field? Get an instant guide explaining the change to your team.

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

Text Chat Completion

Tool to generate text completions or chat responses using a specified llm model. use after assembling the conversation history to produce the next response.

Why this helps

Column changes confuse teams. Tribal knowledge about schema changes isn't documented; teams struggle with implications.

  • Team understands schema changes instantly with no confusion
  • Change impact is documented automatically
  • Reduces support questions about new columns or removed fields
  • Improves data consistency and usage

Setup

Build it in a few focused steps.

  • 1Connect Notion to Notis and select your data source.
  • 2Ask Notis 'Explain schema changes whenever I update columns' or create via Automations.
  • 3Notis monitors your data source and detects column additions, removals, and renames.
  • 4Choose where to post explanations (Slack channel, team email, or in a Notion updates page).
  • 5Add or rename a test column and verify the explanation is generated immediately.

Questions about this workflow

Will Notis explain what each new column should contain?

Yes. If you name columns descriptively, Notis explains the purpose. Vague names get a generic explanation you can refine.

What if I rename a column?

Notis detects the rename and explains what changed and why. Add context when renaming and Notis includes it.

Can I suppress notifications for minor schema tweaks?

Yes. Configure Notis to alert only on significant changes and ignore cosmetic edits.

Supported Triggers and Actions

Notis builds workflows that link Notion to Ai ml api. A trigger fires from one place; an action lands in another.

Recurring trigger

Notis starts this workflow on a schedule, such as daily, weekly, or during business hours.

All Page Events

Triggers when any Notion page is created or updated across the workspace.

TriggerPolling

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.

TriggerInstant

New Comment

Triggers when a new comment is added to a specified Notion block or page.

TriggerPolling

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.

TriggerInstant

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.

TriggerInstant

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.
