Keep localized product demos aligned with updates
When the source demo notes change, make the next translation step easier to remember and run.
Trigger
Page Content Updated
Triggers when the body content of a Notion page is 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 page content edit in the workspace the integration has access to. Notion aggregates content edits within a short window (~60s typical).
Action
Post video translate request
The translatevideo endpoint enables the translation of video content from one language to another. it offers flexible options for translating either the entire video or just the audio track, accommodating various use cases. this tool is ideal for creating multilingual versions of video content, making it accessible to a global audience. the endpoint requires specifying the source video url and the desired output language, with additional options to customize the translation process, such as handling multiple speakers and setting a title for the translated video. use this endpoint when you need to quickly and efficiently translate video content while maintaining the integrity of the original presentation.
Why this helps
Localized demos drift when updates to the original are easy to miss across languages and launch tasks.
- Tie translation requests to changes in the source notes.
- Reduce the chance of forgetting localization after an update.
- Keep language work connected to one Notion reference page.
Setup
Build it in a few focused steps.
- 1Connect Notion and Heygen to Notis once through the portal.
- 2Create an automation in the portal or ask Notis conversationally.
- 3In one instruction, ask Notis to translate the referenced Heygen demo into your specified target language when the source page changes; select Page Content Updated, choose a run-report channel, and test with one real demo update.
Questions about this workflow
Does this create a translation from the Notion page alone?
The Heygen translation action needs a source video URL and target language. Include where Notis should find these in the instruction or page context.
Can it translate to multiple languages?
Specify the target language or languages in your plain-language instruction.

Supported Triggers and Actions
Notis builds workflows that link Notion to Heygen. A trigger fires from one place; an action lands in another.
Notion triggers
Heygen actions
Recurring trigger
Notis starts this workflow on a schedule, such as daily, weekly, or during business hours.
Add new asset
Creates a new asset in the heygen platform. this endpoint allows users to add various types of assets that can be used in video generation, such as avatars, backgrounds, or other content elements. the asset is created by sending plain text data, which likely includes necessary metadata or configuration information. this tool should be used when integrating new assets into the heygen ecosystem for use in content creation workflows. it's important to note that this endpoint may not support direct file uploads; instead, it might expect references to pre-uploaded files or configuration data for asset creation.
Webhook trigger
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Add contact to personalized video project
This endpoint allows you to add one or more contacts to a specific personalized video project in the heygen platform. it is used when you need to associate individual contact information with a project, likely for the purpose of creating tailored video content for each contact. the endpoint accepts a project identifier and a list of contacts, each with a first name and email address. this tool is essential for populating your project with recipient data, enabling the creation of personalized videos at scale. note that this endpoint only adds contacts to a project; it does not initiate video creation or sending. ensure that your project id is valid and that all contact information is accurate to avoid errors in video personalization or delivery.
All Page Events
Triggers when any Notion page is created or updated across the workspace.
Retrieve audience video details
Retrieves detailed information about the audience for personalized videos. this endpoint provides insights into the target audience characteristics, preferences, and engagement metrics for heygen's ai-generated personalized video content. it can be used to gain a deeper understanding of the audience demographics, behavior patterns, and content preferences to optimize video creation and targeting strategies. the tool is particularly useful for content creators, marketers, and businesses looking to tailor their video content to specific audience segments using heygen's ai capabilities.
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.
Fetch personalized video project detail
Retrieves detailed information about a specific personalized video project in the heygen platform. this endpoint allows you to fetch comprehensive data about a project, including its current status, configuration settings, and any other relevant metadata. use this when you need to get an up-to-date overview of a particular video project, such as checking its progress, reviewing its settings, or gathering information for reporting purposes. the endpoint is read-only and does not modify any project data. note that it may not include the actual video content itself, but rather focuses on the project's attributes and status.
New Comment
Triggers when a new comment is added to a specified Notion block or page.
Post talking photo binary image
Creates a talking photo by processing an uploaded image file. this endpoint enables users to transform static images into interactive, speaking visual content using heygen's advanced ai technology. it accepts jpeg or png image files and likely combines them with audio narration (though audio input is not specified in this schema). use this endpoint when you want to generate engaging, personalized content from still images, such as creating speaking avatars or animated photographs. the endpoint is particularly useful for marketing materials, educational content, or personalized messages. note that while image upload is specified, the method for providing or generating the associated audio is not detailed in this schema.
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 streaming avatars
Retrieves a list of available avatars for streaming purposes in the heygen platform. this endpoint allows developers to access the collection of realistic avatars that can be used for creating professional-looking videos with ai-generated content. it's designed to support applications requiring dynamic or live video content, enabling real-time access to the avatar library. the endpoint should be used when you need to fetch the current set of available avatars for integration into streaming or video generation workflows. it may not provide detailed information about each avatar's capabilities or customization options, focusing instead on delivering a quick, up-to-date list for immediate use in streaming contexts.
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 streaming token with expiry
Creates a new streaming token for use with heygen's real-time avatar and voice chat services. this endpoint generates a unique, time-limited token that authenticates and authorizes access to heygen's streaming capabilities. use this endpoint when initiating a new streaming session or when the previous token has expired. the generated token is typically for one-time use and should be obtained shortly before starting a streaming interaction. note that this endpoint does not initiate the streaming itself; it only provides the necessary credentials for subsequent streaming api calls.
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.
Post streaming ice candidates
This endpoint is used to submit ice (interactive connectivity establishment) candidate information for a specific streaming session in the heygen platform. it plays a crucial role in establishing and managing peer-to-peer connections for real-time communication and streaming of avatar content. the endpoint should be called when new ice candidates are discovered during the connection setup process, typically as part of the webrtc negotiation. it's essential for ensuring optimal connectivity between clients, especially in scenarios involving nat traversal or complex network environments. this endpoint does not return the status of the connection or initiate the streaming itself; it only submits candidate information to be used in the connection process.
