Check preview tunnels when a Notion status changes
A status update in Notion can cue a fresh view of active tunnels, so preview readiness is easier to check in the flow of work.
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 Active Tunnels
List all active tunnels in the ngrok account. this tool lists all active tunnels in the ngrok account, providing details such as tunnel id, public url, start time, protocol, configuration details, and metadata. it requires no input parameters beyond authentication and returns a paginated list of all running tunnels with their complete status information.
Why this helps
Preview readiness may change while the task status gets updated, leaving teams to remember a separate tunnel check.
- Pair task status changes with a current tunnel inventory.
- Make preview checks part of the update that already happens in Notion.
- Give collaborators a clear report when tunnel availability matters.
Setup
Build it in a few focused steps.
- 1Connect Notion and Ngrok to Notis once in the portal.
- 2Create an automation by asking Notis for a tunnel status report after a Notion status changes.
- 3Choose the Notion Page Properties Updated trigger and a reporting channel.
- 4Test with one real status update and check the resulting tunnel report.
Questions about this workflow
Does a status change guarantee the preview is ready?
No. The automation reports active tunnels; use the report to assess whether the expected preview is present.
Can I limit the trigger to one database?
Yes. Select the Page Properties Updated event scoped to the relevant data source.

Supported Triggers and Actions
Notis builds workflows that link Notion to Ngrok. A trigger fires from one place; an action lands in another.
Notion triggers
Ngrok actions
Recurring trigger
Notis starts this workflow on a schedule, such as daily, weekly, or during business hours.
Create API Key
Creates a new api key for authenticating with the ngrok api. this tool allows programmatic creation of api keys that can be used to access ngrok's api services.
Webhook trigger
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Delete API Key
Delete an api key by its id. this action permanently removes the specified api key from your ngrok account. this is an important security feature that allows users to revoke access when an api key is compromised or no longer needed. once deleted, the api key cannot be recovered and any services using it will lose access.
All Page Events
Triggers when any Notion page is created or updated across the workspace.
Get IP Restriction Details
This tool retrieves detailed information about a specific ip restriction by its id. it is used to control which ip addresses can access ngrok resources, including the api, by fetching complete details of the ip restriction. this action is essential for auditing and verification in ip restriction management.
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 API Keys
This tool lists all api keys owned by the user. the api keys are used to authenticate api requests to ngrok's rest api. the endpoint returns a paginated list of api keys.
New Comment
Triggers when a new comment is added to a specified Notion block or page.
List All Endpoints
List all active endpoints on the ngrok account. this tool will list all active endpoints on the ngrok account, providing visibility into running tunnels and endpoints. it requires no input parameters beyond authentication and serves as a fundamental component for monitoring, managing, and referencing ngrok resources.
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 HTTPS Edges
Lists all https edges in your ngrok account. https edges are configurations that tell ngrok how to handle https traffic. the action returns a paginated list of all https edges associated with your account.
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 IP Policy Rules
This tool lists all ip policy rules associated with your ngrok account. it retrieves detailed information including rule id, creation timestamp, description, metadata, cidr, the associated ip policy, and the action (allow or deny) for each rule. it supports pagination with parameters 'limit' for the maximum number of results and 'before id' for pagination.
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 IP Restrictions
This tool retrieves a list of all ip restrictions configured on the ngrok account. it allows users to audit and review all ip-based access restrictions on their ngrok account for enhanced security management. the api endpoint supports pagination with optional parameters such as 'limit' and 'before id', and returns a detailed json response containing attributes like id, uri, created at, description, metadata, enforced, type, and associated ip policies.
