Example Workflows (Ready to Adapt) – Notion: Enrich Pages with Generated Documentation

This workflow demonstrates how to automatically enrich Notion pages containing code snippets. It fetches entries from a Notion database, generates comprehensive documentation via the DocuWriter.ai node, then appends generated content back to each Notion page.

Workflow Steps

1. 📓 Get Notion Database
   Retrieve pages from a specified Notion database.
2. 📝 Extract Code from Notion
   Filter pages that include a Code rich-text property and prepare metadata for each.
3. 🤖 Generate Notion Documentation
   Use the DocuWriter.ai action node to generate structured documentation for each code snippet.
4. 📎 Update Notion Page
   Append a heading and the generated documentation back to the original Notion page.

Node Breakdown

Configuration Details

1. Get Notion Database

{
  "parameters": {
    "authentication": "oAuth2",
    "resource": "database",
    "operation": "getMany",
    "databaseId": "<YOUR_DATABASE_ID>",
    "options": {}
  }
}

2. Extract Code from Notion

This Code node scans each returned page, looks for a Code rich-text property, and emits items only for pages containing code.

// Node: Extract Code from Notion
const pages = $json.results || [];
const codePages = [];

for (const page of pages) {
  const props = page.properties;
  if (props['Code']?.rich_text?.length > 0) {
    codePages.push({
      json: {
        notion: {
          pageId: page.id,
          fileName: props['Name']?.title?.[0]?.plain_text || 'Untitled',
          language: props['Language']?.select?.name || 'text',
          codeContent: props['Code'].rich_text[0].plain_text
        }
      }
    });
  }
}

return codePages;

3. Generate Notion Documentation

The DocuWriter.ai node takes the extracted code and generates structured documentation, formatted for Notion integration.

{
  "parameters": {
    "sourceCode": "={{ $json.notion.codeContent }}",
    "generationType": "Documentation",
    "mode": "accurate",
    "additionalInstructions": "Create comprehensive documentation for {{ $json.notion.fileName }}. Include detailed explanations, usage examples, and best practices. Format for Notion page integration."
  },
  "type": "docuwriter-ai",
  "name": "Generate Notion Documentation"
}

4. Update Notion Page

This Notion node appends blocks under each page with a heading and the generated documentation.

{
  "parameters": {
    "authentication": "oAuth2",
    "resource": "block",
    "operation": "append",
    "pageId": "={{ $json.notion.pageId }}",
    "blockUi": {
      "blockValues": [
        {
          "type": "heading_2",
          "rich_text": "📚 Generated Documentation"
        },
        {
          "type": "paragraph",
          "rich_text": "{{ $json.generatedContent }}"
        },
        {
          "type": "paragraph",
          "rich_text": "Generated by DocuWriter.ai on {{ new Date().toLocaleDateString() }}"
        }
      ]
    }
  },
  "type": "n8n-nodes-base.notion",
  "name": "Update Notion Page"
}

Tips for Adaptation

• Batch Size: Limit the number of pages processed per run to manage rate limits.
• Error Handling: Add “IF” nodes to catch missing properties or API errors.
• Customization: Adjust additionalInstructions in the DocuWriter.ai node to tailor tone or format.
• Scheduling: Use a Cron-trigger to run this enrichment at desired intervals.
