Give new Notion data sources a Mem collection
Start an organized home for notes related to each new data source.
Trigger
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.
Action
Create Collection
Tool to create a new collection in mem. use when you want to group related notes into a dedicated collection after confirming the title.
Why this helps
A new database source can introduce a fresh stream of information with nowhere obvious to collect related notes.
- Set up a dedicated place for related Mem notes.
- Make new information streams easier to organize.
- Reduce setup decisions for a new workspace area.
Setup
Build it in a few focused steps.
- 1Connect Notion and Mem to Notis once through the portal.
- 2Create an automation and instruct Notis in plain language to create a Mem collection for each new data source.
- 3Choose Data Source Created as the trigger.
- 4Choose a reporting channel and test with a real new data source.
Questions about this workflow
Can one template create several collection events?
Yes. A template-based creation can emit one event for each data source it instantiates.
When is a collection preferable to a note?
Choose a collection when related information will accumulate as multiple notes.

Supported Triggers and Actions
Notis builds workflows that link Notion to Mem. A trigger fires from one place; an action lands in another.
Notion triggers
Mem actions
Recurring trigger
Notis starts this workflow on a schedule, such as daily, weekly, or during business hours.
Create Collection
Tool to create a new collection in mem. use when you want to group related notes into a dedicated collection after confirming the title.
Webhook trigger
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Create Note
Tool to create a new note in mem. use when you have note content and optional metadata ready to be saved. supports idempotent creation via memid.
All Page Events
Triggers when any Notion page is created or updated across the workspace.
Delete Collection
Tool to delete a mem collection. use after confirming the collection id you wish to remove.
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.
Delete Note
Tool to delete a specific note. use when you need to remove a note by its unique identifier after confirming the note id.
New Comment
Triggers when a new comment is added to a specified Notion block or page.
Read Note
Tool to retrieve the content and metadata of a mem note. use after confirming you have the note's id.
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.
