- Standardizing data during team collaboration to prevent duplicate submissions
- Periodic cleanup of historical records or project entries to optimize database structure
- Suitable for scenarios requiring precise data maintenance such as project management, client information repositories, and content libraries
Main Workflow Steps
- Trigger: Supports two trigger modes — (1) automatic trigger when a new page is added to the database; (2) scheduled daily run to ensure continuous data cleanup.
- Retrieve Database Pages: Connect to the Notion API to fetch all pages from the specified database.
- Format Data: Organize page data into a unified format and extract key properties used to identify duplicates.
- Filter Duplicates: Use a custom code node to detect entries with duplicate property values and mark them as duplicates.
