Pair webinar database changes with an event catalog review
When you reshape your webinar database, bring the current Demio event list into the same planning moment.
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
List Demio Events
Tool to retrieve a list of Demio events. Use when you need to fetch events optionally filtered by type or paginated.
Why this helps
Structural changes can leave event tracking unclear until someone separately checks which Demio webinars are active.
- Pair a structural database change with an event-list review.
- See the current event set while revising how webinars are tracked.
- Reduce the separate lookup during workspace maintenance.
Setup
Build it in a few focused steps.
- 1Connect Notion and Demio to Notis once through the portal.
- 2Create an automation through the portal or ask Notis conversationally.
- 3Tell Notis to retrieve Demio events when the webinar data source schema changes.
- 4Choose the Notion Data Source Schema Updated trigger for the relevant data source and select a report channel.
- 5Test by making a schema change and reviewing the resulting event list.
Questions about this workflow
Does this fire for a new database column?
The schema trigger detects column additions, removals, or renames for a data source.
Does it modify the database?
No. It retrieves Demio events for your review.

Supported Triggers and Actions
Notis builds workflows that link Notion to Demio. A trigger fires from one place; an action lands in another.
Notion triggers
Demio actions
Recurring trigger
Notis starts this workflow on a schedule, such as daily, weekly, or during business hours.
Demio Create Join Link
Tool to register an attendee and obtain their unique Demio join link. Use after confirming a valid event_id.
Webhook trigger
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Demio: Get Event by ID
Tool to retrieve event details by ID. Use when you need the full metadata for a specific Demio event.
All Page Events
Triggers when any Notion page is created or updated across the workspace.
List Event Date Participants
Tool to list participants for a specific event date. Use after scheduling an event session to retrieve attendees.
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.
List Event Dates
Tool to list all scheduled session dates for a given Demio event. Use when you need the session schedule by event ID.
New Comment
Triggers when a new comment is added to a specified Notion block or page.
List Demio Events
Tool to retrieve a list of Demio events. Use when you need to fetch events optionally filtered by type or paginated.
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.
Demio API Ping
Tool to perform a health check on the Demio API. Use to verify the API is reachable before other calls.
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.
