Who is this workflow for? Connect your Notion databases to real-time webhooks using Supabase and n8n. This workflow ensures updates from Notion are delivered every five seconds, overcoming Notion’s lack of native webhook support and enhancing your automation capabilities..

What does this workflow do?

  • Setup Supabase:
  • Create a new project in Supabase.
  • Import the provided database schema from Gumroad to manage cached states.
  • Configure Notion Database:
  • Add a “Last edited time” property to your Notion database if it doesn’t already exist.
  • Define Global Settings in n8n:
  • Enter the dynamically generated settings_id from the Supabase settings table.
  • Input your Notion Database URL into the Globals node.
  • Webhook Configuration:
  • Specify your custom Webhook URL in the final node to receive updates.
  • Prevent Simultaneous Executions:
  • Use the recommended Redis template to avoid overlapping workflow runs.
  • Set Polling Interval:
  • Configure the Schedule Trigger to poll every five seconds, balancing real-time needs with system performance.
  • Workflow Execution:
  • The workflow polls the Notion database for changes based on the “Last edited time.”
  • Retrieved pages are compared with cached versions in Supabase.
  • Only new or modified pages are sent to the registered webhook, ensuring efficient data updates.

🤖 Why Use This Automation Workflow?

  • Immediate Updates: Receive notifications within five seconds of any change in your Notion database.
  • Efficient Polling: Reduces server load by efficiently polling and comparing database states.
  • Selective Notifications: Only new and changed data is pushed, minimizing unnecessary information flow.
