Review Demio attendance after an attendee record changes
A small update to an attendee record can cue a fresh participant-list check, making it easier to reconcile your follow-up plan.
Trigger
Page Properties Updated
Triggers when properties of a Notion page are updated. Customer optionally scopes with at most one of: - data_source_id: any row in this data source - page_id: this specific page - parent_page_id: any page whose immediate parent is this page With none set, fires for any property change in the workspace the integration has access to. Adding a column to a data source fires this trigger once per existing row. Customers can branch on `data.updated_properties` (array of property IDs) to filter downstream.
Action
List Event Date Participants
Tool to list participants for a specific event date. Use after scheduling an event session to retrieve attendees.
Why this helps
Attendee tracking across separate tools can leave you unsure whether your Notion list reflects the latest session participants.
- Retrieve a participant list when attendee properties change.
- Use current Demio session data to inform follow-up planning.
- Keep reconciliation connected to the record that prompted it.
Setup
Build it in a few focused steps.
- 1Connect Notion and Demio to Notis once through the portal.
- 2Create an automation in the portal or ask Notis to make one conversationally.
- 3Tell Notis to list Demio participants for the session identified by the changed attendee record.
- 4Select the Notion Page Properties Updated trigger for the attendee data source and choose a report channel.
- 5Test with a changed record that references a valid event and session date.
Questions about this workflow
What does the participant action need?
It retrieves participants for a specific event date, so the Notion context should identify the event and date.
Does this update attendee records?
The listed action retrieves participants. It does not change Notion records.

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.
