notion.onDataSourceSchemaUpdated start an automation when a data-source property schema changes.

Example

automations/notion-on-data-source-schema-updated.automation.ts

Configuration

The trigger takes no event filters. Its optional static account selects a named OAuth binding and defaults to the project’s Notion binding. Personal access tokens cannot own webhook subscriptions.

Event

Returns the typed schema-update payload. Optional data.updatedProperties identifies created, updated, or deleted property IDs and names. The event is narrowed to data_source.schema_updated; consumers do not need to inspect the raw type. Automate.ax verifies the Notion signature, routes only to an eligible workspace principal, and deduplicates provider retries by event ID.
