Turn incoming image links into optimized assets
Let a custom backend hand image links to Notis for Kraken.io optimization, then get a clear result report.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Optimize Image by URL
Tool to optimize an image from a public url. use when you need to compress, resize, or convert an externally hosted image. returns result immediately if 'wait' is true.
Why this helps
Images entering through custom intake can become disconnected from the people responsible for preparing them.
- Bring custom intake into the same automation flow.
- Reduce manual handoffs after an image arrives.
- Keep optimization results visible in a chosen channel.
Setup
Build it in a few focused steps.
- 1Connect Kraken.io to Notis once; connect Notion too if it holds the asset record.
- 2Create an automation in the portal or ask Notis to create a webhook-triggered workflow.
- 3Tell Notis to optimize the public image URL received from your custom backend and report the result.
- 4Select an incoming Notis webhook trigger and choose a channel for run reports.
- 5Send one real test request with an externally hosted image URL.
Questions about this workflow
Does the webhook need to come from Notion?
No. A Notis webhook can start the workflow when an external tool or custom backend sends an HTTP request.
Can this accept a local file path?
Use a public image URL that Kraken.io can access.

Supported Triggers and Actions
Notis builds workflows that link Notion to Kraken io. A trigger fires from one place; an action lands in another.
Notion triggers
Kraken io actions
Recurring trigger
Notis starts this workflow on a schedule, such as daily, weekly, or during business hours.
Check Kraken.io User Status
Tool to retrieve current kraken.io account status and quota usage. use when you need to verify plan limits and remaining quota before processing images.

Optimize Image by URL

All Page Events
Triggers when any Notion page is created or updated across the workspace.
Preserve Image Metadata
Tool to preserve exif and other metadata during kraken.io image optimization. use when you need to maintain metadata while compressing images.
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.
Sandbox Image Upload
Tool to upload and optimize images in sandbox mode. use when you want to test the kraken.io api without consuming credits.
New Comment
Triggers when a new comment is added to a specified Notion block or page.
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.
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.
