Know what a database change means for your workflow
When a Notion data source schema changes, get a concise explanation of the update and questions to check.
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
Generate Text
Tool to generate text for a project model. Use when you need LLM completions or chat responses. Supports both prompt and message-based inputs with temperature, stop-sequence, and token limits.
Why this helps
Column changes can affect routines and views, but the reason or impact may not be obvious to everyone.
- Makes structural changes easier to understand.
- Prompts a quick check for affected routines.
- Reduces the need to manually translate technical change details.
Setup
Build it in a few focused steps.
- 1Connect Notion and MetatextAI to Notis once through the portal.
- 2Create an automation and ask Notis to explain data source schema updates.
- 3Use one plain-language instruction to summarize added, removed, or renamed properties and flag likely review questions.
- 4Select Data Source Schema Updated and choose a channel for run reports.
- 5Test with one real schema change event when available, or verify the prompt with a representative example.
Questions about this workflow
Does it run for every existing row when a column is added?
Use Data Source Schema Updated to receive one structural-change signal instead of relying on per-row property updates.
Can the output state downstream impact for certain?
It can flag questions to investigate, but should not claim an impact that is not supported by the event context.

Supported Triggers and Actions
Notis builds workflows that link Notion to Metatextai. A trigger fires from one place; an action lands in another.
Notion triggers
Metatextai actions
Recurring trigger
Notis starts this workflow on a schedule, such as daily, weekly, or during business hours.
Chat Completions
Tool to generate chat completions. Use when you need OpenAI-compatible conversational responses.
Webhook trigger
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Classify Text
Tool to classify text. Use when you need to obtain labels and confidence scores from a trained MetatextAI model for given text.
All Page Events
Triggers when any Notion page is created or updated across the workspace.
Create Policy Guardrails
Tool to create a policy guardrail. Use when you need to define automated guardrails for content in a specific application.
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.
Delete Guardrail Policy
Tool to delete a guardrail policy. Use when you need to remove a policy by ID for a specific application after confirming valid application and policy IDs.
New Comment
Triggers when a new comment is added to a specified Notion block or page.
Evaluate Messages
Tool to evaluate LLM messages against policies/guardrails. Use after generating model output to get violation details or corrections.
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.
Run Extraction
Tool to run information extraction. Use when you need to extract structured data from text.
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.
Generate Text
Tool to generate text for a project model. Use when you need LLM completions or chat responses. Supports both prompt and message-based inputs with temperature, stop-sequence, and token limits.
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.
List Applications
Tool to retrieve a list of all existing applications. Use when you need to view application IDs, names, and descriptions.
