Add Notion Comments from External Webhooks

Whenever an external tool sends data via webhook, Notis adds a comment to your Notion page, keeping your team informed and searchable.

Trigger

Webhook received

Notis starts this workflow when an external tool or custom backend sends an HTTP request.

Action

Fetch comments

Fetches unresolved comments for a specified notion block or page id.

Why this helps

Important updates come from external tools, but they don't automatically appear in Notion. Your team misses notifications and information gets lost.

  • Sync notifications and updates from external tools directly to Notion
  • Keep your team informed without manual posting
  • Build a searchable audit trail of all external events
  • Reduce notification fatigue by centralizing alerts in Notion

Setup

Build it in a few focused steps.

  • 1Connect your Notion workspace to Notis.
  • 2Create an automation: 'When a webhook receives data, add a comment to my Notion page with the details.'
  • 3Notis provides a webhook URL to add to your external tool or backend.
  • 4Specify the Notion page and the format for comments.
  • 5Send a test webhook and verify the comment appears in Notion.

Questions about this workflow

Can comments include data from the webhook payload?

Yes. Notis extracts relevant fields from the webhook data and formats them into readable comments.

Can different webhooks add comments to different pages?

Yes. Specify routing rules (e.g., 'webhooks from system A go to page X, system B go to page Y').

Can I notify specific people when a comment is added?

Yes. Notis can mention or tag team members in comments to draw their attention.

Supported Triggers and Actions

Notis builds workflows that link Whatsapp to Notion. A trigger fires from one place; an action lands in another.

Message Status Updated

Triggers when a WhatsApp message status changes. IMPORTANT LIMITATION: WhatsApp Cloud API does not provide a native polling endpoint for message status. Status updates are ONLY delivered via webhooks in real-time. This trigger cannot directly poll the WhatsApp API for status updates. This trigger will return empty results as WhatsApp does not support this operation. To track message status updates, you must: 1. Set up a webhook endpoint to receive status notifications from WhatsApp 2. Store the webhook data in your own database 3. Use a different mechanism to query your stored webhook data For more information, see: - https://developers.facebook.com/docs/whatsapp/cloud-api/webhooks

TriggerPolling

Add multiple content blocks (bulk, user-friendly)

Efficiently adds multiple standard content blocks to a notion page in a single api call with automatic markdown parsing. the 'content' field in notionrichtext blocks now automatically detects and parses markdown formatting including headers (# ## ###), bold (**text**), italic (*text*), strikethrough (~~text~~), inline code (`code`), links ([text](url)), and more. ideal for bulk content creation, ai agents, and replacing multiple individual add page content calls. supports automatic text formatting, content splitting, and up to 100 blocks per request.
