Make Notion schema changes easier to understand
Translate a column change into a short explanation of what to check next.
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 Chat Completion
Tool to generate a response given a list of messages in a conversational context. Supports both conversational Language Models (LLMs) and Vision-Language Models (VLMs). Compatible with OpenAI SDK.
Why this helps
A changed database column can quietly break routines that depend on its name or meaning.
- Explain structural changes in plain language.
- Prompt a quick check of dependent routines.
- Reduce surprise when a field is renamed or removed.
Setup
Build it in a few focused steps.
- 1Connect Notion and Hugging Face to Notis once through the portal.
- 2Create an automation in the portal or ask Notis to summarize schema changes.
- 3Give Notis one instruction to send the schema update details to Hugging Face and return a brief impact summary with suggested checks.
- 4Choose the Notion Data Source Schema Updated trigger and a channel for run reports.
- 5Test by adding or renaming a safe column and review the summary.
Questions about this workflow
Will it detect every dependent workflow?
The summary can suggest checks from the supplied change details, but it cannot know every dependency unless you provide that context.
Can it focus on renames or removals?
Ask Notis to tailor the summary to the updated property actions included with the event.

Supported Triggers and Actions
Notis builds workflows that link Notion to Hugging Face. A trigger fires from one place; an action lands in another.
Notion triggers
Hugging Face actions
Recurring trigger
Notis starts this workflow on a schedule, such as daily, weekly, or during business hours.
Change Discussion Status
Tool to change the status of a Hugging Face repository discussion. Use when you need to open or close discussions on models, datasets, or spaces.
Webhook trigger
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Check Dataset Validity
Tool to check whether a specific dataset is valid on Hugging Face Hub. Use when you need to determine what features (preview, viewer, search, filter, statistics) are available for a dataset.
All Page Events
Triggers when any Notion page is created or updated across the workspace.
Check Models Upload Method
Tool to check if files should be uploaded through the Large File mechanism or directly. Use when preparing to upload files to a Hugging Face model repository to determine the appropriate upload method for each file.
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.
Check Spaces Upload Method
Tool to check if files should be uploaded through the Large File mechanism or directly to Hugging Face Spaces. Use when preparing to upload files to a Hugging Face Space repository to determine the appropriate upload method for each file.
New Comment
Triggers when a new comment is added to a specified Notion block or page.
Claim Paper Authorship
Tool to claim authorship of a paper on Hugging Face. Use when you need to associate yourself or another user with an ArXiv paper.
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.
Request Repository Access
Tool to request access to a gated repository on Hugging Face Hub. Use when you need to submit an access request for models, datasets, or Spaces that require approval. The fields required vary by repository.
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.
Create Collection
Tool to create a new collection on Hugging Face. Use when you need to organize and curate models, datasets, spaces, papers, or other collections into a named collection.
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.
Create Datasets Branch
Tool to create a new branch in a Hugging Face dataset repository. Use when you need to create a branch for versioning or experimentation with dataset changes.
