Keep your research fields aligned with the information you need
When a database structure changes, check a relevant website for the facts your new fields are meant to capture.
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
Extract Structured Data
Crawl a website and return JSON matching a caller-supplied JSON Schema.
Why this helps
Adding or renaming properties can leave a research system out of step with the information the team actually needs.
- Review schema decisions against current source material.
- Spot missing research fields earlier.
- Make structural changes more intentional.
Setup
Build it in a few focused steps.
- 1Connect Notion and Context.dev to Notis once in the portal.
- 2Create an automation in the portal or ask Notis conversationally.
- 3Write one instruction describing the website and facts to extract when a tracked data source schema changes.
- 4Choose Data Source Schema Updated as the trigger and pick a run-report channel.
- 5Test by making a meaningful schema change and reviewing the output.
Questions about this workflow
Does this trigger fire for every row?
No. It is a structural-change signal for a data source, designed to distinguish schema changes from page property updates.
Can the workflow focus on one data source?
The trigger supports an optional data_source_id scope for a specific source.

Supported Triggers and Actions
Notis builds workflows that link Notion to Context.dev. A trigger fires from one place; an action lands in another.
Notion triggers
Context.dev actions
Recurring trigger
Notis starts this workflow on a schedule, such as daily, weekly, or during business hours.
Extract Structured Data
Crawl a website and return JSON matching a caller-supplied JSON Schema.
Webhook trigger
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Retrieve Brand
Resolve a company by domain, name, or ticker into a full brand profile.
All Page Events
Triggers when any Notion page is created or updated across the workspace.
Identify Transaction
Map a noisy card or bank descriptor to the real merchant and its brand data.
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.
Scrape Images
Extract every image asset from a page with metadata.
New Comment
Triggers when a new comment is added to a specified Notion block or page.
Web Search
Search the web and optionally scrape each result to Markdown in one call.
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.
Extract Styleguide
Extract a website's design system: colors, typography, spacing, shadows, and UI components.
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.
