Check a selected experience before it enters the plan
When you add an experience to a trip page, Notis can check Headout inventory for the specified variant and report its available pricing.
Trigger
Page Added to Page
Fires when a new subpage (a `child_page` type block) is added under a specified parent Notion page.
Action
List Inventory by Variant
Tool to retrieve available inventory and pricing for a specific product variant. Use when you need to check availability and pricing details for booking.
Why this helps
A saved activity can look like a good fit until you discover that its timing or availability does not work.
- Check variant inventory while you are adding an experience to your plan.
- Catch availability and pricing information before spending more time on an option.
Setup
Build it in a few focused steps.
- 1Connect Notion and Headout to Notis once through the portal.
- 2Create an automation in the portal or ask Notis in plain language.
- 3Write one instruction asking Notis to check inventory for the product variant identified in a new trip subpage.
- 4Select the Notion Page Added to Page trigger and choose a channel for run reports.
- 5Test by adding a subpage with a real Headout product and variant reference.
Questions about this workflow
Does this book the variant?
No. It checks inventory and pricing only; it does not make a reservation.
What details are needed?
Notis needs to identify a Headout product variant from the page context. Include the clearest reference available in your note.

Supported Triggers and Actions
Notis builds workflows that link Notion to Headout. A trigger fires from one place; an action lands in another.
Notion triggers
Headout actions
Recurring trigger
Notis starts this workflow on a schedule, such as daily, weekly, or during business hours.
Get Product By ID
Tool to retrieve detailed product information by product ID. Use when you need comprehensive product details including pricing, images, location, variants, and availability.
Webhook trigger
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
List Categories V2
Tool to fetch all available activity categories for a specific city using V2 API. Use when you need to list categories of activities available in a particular city location.
All Page Events
Triggers when any Notion page is created or updated across the workspace.
List Cities
Tool to list all active cities with pagination support. Use when you need to retrieve available cities from the Headout platform. Supports pagination through offset and limit parameters.
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 Collections V2
Tool to fetch all collections for a specific city using V2 API with pagination support. Use when you need to browse collections available in a particular city, with optional language-specific content and pagination controls.
New Comment
Triggers when a new comment is added to a specified Notion block or page.
List Inventory by Variant
Tool to retrieve available inventory and pricing for a specific product variant. Use when you need to check availability and pricing details for booking.
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.
List Products By Category
Tool to list product listings filtered by category ID with pagination support. Use when you need to retrieve products for a specific category.
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.
List Products V2
Tool to fetch products using Headout V2 API with filtering by city, collection, category, or subcategory. Use when you need to retrieve product listings for specific locations or categories with pagination support.
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 Subcategories V2
Tool to fetch all subcategories for a specific city using V2 API. Use when you need to list subcategories of activities available in a particular city location.
