Register MailerLite webhooks from an operations plan
When your email operations plan is ready, use its Notion update to prompt MailerLite webhook setup for your chosen endpoint and event types.
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
Create Webhook
Tool to register a new webhook url for specified event types. use when you need real-time notifications for selected mailerlite events.
Why this helps
Integration setup often gets deferred because endpoint details and event choices need a focused pass.
- Tie integration setup to a planned operations milestone.
- Reduce the chance webhook setup gets lost in a checklist.
- Create a visible handoff from planning to configuration.
Setup
Build it in a few focused steps.
- 1Connect Notion and MailerLite to Notis once.
- 2Ask Notis to register the MailerLite webhook when the specified operations page is marked ready, using the approved URL and event types.
- 3Select Page Content Updated for the operations page.
- 4Choose a channel to receive run reports.
- 5Test with the approved endpoint and confirm the webhook appears in MailerLite.
Questions about this workflow
What details are needed for webhook registration?
The automation needs a destination URL and selected MailerLite event types. Provide these in the instruction only when they are known and approved.
Does updating the page repeatedly create duplicate webhooks?
Describe a clear readiness condition and verify the outcome. Repeated registration behavior depends on the workflow and available identifiers.

Create/Update E-commerce Customer
Tool to create or update a customer record for a shop. use when syncing shop customers or onboarding new purchases.
All Page Events
Triggers when any Notion page is created or updated across the workspace.
Create E-commerce Shop
Tool to connect a new e-commerce shop. use when you need to integrate a store for automations, product imports, and sales tracking.
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.
Create Field
Tool to create a new custom field. use when distinct subscriber attributes are needed before assigning or updating subscriber data. call once per field key.
New Comment
Triggers when a new comment is added to a specified Notion block or page.
Create Group
Tool to create a new subscriber group. use after deciding the group name for categorization.
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.
Create Segment
Tool to create a new subscriber segment. use when grouping subscribers by custom criteria before sending targeted campaigns.
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 Webhook
Tool to register a new webhook url for specified event types. use when you need real-time notifications for selected mailerlite events.
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.
Delete Automation
Tool to delete an automation workflow by id. use when you need to remove an automation after confirming it's no longer needed. returns success=true on 204 no content.
