Auto-Generate Data Dictionaries for New Data Sources
New data source? Get a complete data dictionary instantly. No documentation work required.
Trigger
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.
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
New data sources lack documentation. Creating it feels like busywork that gets postponed indefinitely.
- Data dictionaries appear instantly with zero documentation effort
- Ensures data consistency and correct usage
- Speeds up data onboarding for new team members
- Improves data quality and governance
Setup
Build it in a few focused steps.
- 1Connect Notion to Notis in the portal.
- 2Ask Notis 'Generate a data dictionary whenever I create a new data source' or set up via Automations.
- 3Notis inspects the new data source schema and generates comprehensive documentation.
- 4Specify where the dictionary should live (Notion page, shared document, or wiki).
- 5Create a test data source and review the auto-generated dictionary for accuracy.
Questions about this workflow
What does the generated data dictionary include?
Field names, types, descriptions, example values, relationships to other sources, and validation rules.
Can I customize the dictionary after it's generated?
Absolutely. Add business context, usage examples, and governance notes. Notis learns from your edits.
What if my data source has complex relationships?
Add relationship metadata when creating the source. Notis includes that in the dictionary for clarity.

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.
Notion triggers
Ai ml api actions
Recurring trigger
Notis starts this workflow on a schedule, such as daily, weekly, or during business hours.
Moderation Completion
Tool to classify input text or image for safety using a moderation model. use after receiving user-generated content to filter out unsafe material.
Webhook trigger
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
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.
All Page Events
Triggers when any Notion page is created or updated across the workspace.
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.
New Comment
Triggers when a new comment is added to a specified Notion block or page.
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.
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.
