Notion Webhook Emulator: Real-Time Updates Powered by Supabase
detail.loadingPreview
This n8n workflow ingeniously emulates real-time webhooks for Notion database changes. By leveraging Supabase for historical data storage, it precisely detects new or updated Notion pages and dispatches these changes as a custom payload to any HTTP endpoint.
About This Workflow
This powerful n8n workflow addresses a common challenge by transforming Notion into a source of event-driven actions, even without native outgoing webhooks for database changes. It intelligently polls specified Notion databases, stores and compares page states with data persistently saved in Supabase, accurately identifying newly created or updated pages. Once changes are detected, the workflow processes and formats the relevant data, then dispatches a custom payload via an HTTP request. This enables you to trigger downstream automations, send instant notifications, or synchronize data with other applications the moment a change occurs in your Notion workspace, providing a robust solution for enhanced data flow and event-driven workflows.
Key Features
- Notion Webhook Simulation: Effectively emulates real-time webhooks for changes within Notion databases.
- Supabase Data Persistence: Utilizes Supabase to store and manage historical Notion page data, enabling accurate change detection.
- Smart Change Detection: Identifies both newly created and updated Notion pages based on comparisons with stored data.
- Customizable Data Comparison: Features a 'Code' node for flexible and precise comparison logic tailored to your specific Notion fields.
- Flexible Payload Delivery: Sends formatted Notion change events as an HTTP request to any configurable endpoint.
How To Use
- Configure Supabase: Ensure your Supabase credentials are set up. Create two tables: one for storing Notion page data (e.g.,
notion_pageswith relevant fields) and another for workflow settings (e.g.,workflow_settings). - Connect Notion: Provide your Notion API token and the ID of the Notion database you intend to monitor in the 'Get modified tasks' node.
- Define Payload Endpoint: In the 'Push Payload' HTTP Request node, specify the target URL where you want the Notion change events to be sent.
- Customize Change Logic (Optional): If your Notion data has unique comparison requirements, adjust the logic within the 'Compare Data Sets' code node.
- Activate Workflow: Once configured, activate the workflow. It will periodically poll your Notion database, track changes via Supabase, and push detected updates to your specified endpoint.
