Finding Page and Database IDs

From URL

When viewing a page or database in Notion, the ID is in the URL:

https://www.notion.so/My-Page-abc123def456...
                              ^----- This is the ID

Using search_content

Search for pages/databases by title:

{
  "tool": "search_content",
  "arguments": {
    "query": "My Database Name"
  }
}

Development

# Install dependencies
npm install

# Build TypeScript
npm run build

# Watch mode for development
npm run watch

Requirements

• Node.js >= 18.0.0
• Notion API Key
• TypeScript 5.7+

Security

• Never commit your NOTION_API_KEY to version control
• Use environment variables for sensitive credentials
• Regularly rotate your API keys
• Limit integration permissions to only required pages/databases

Troubleshooting

"Error: NOTION_API_KEY environment variable is required"

• Ensure you've set the NOTION_API_KEY environment variable
• Check that the variable is available in the process environment

"Object not found" errors

• Verify the page/database ID is correct
• Ensure your integration has been added to the page/database
• Check that the page/database hasn't been deleted

"Validation failed" errors

• Verify property types match the database schema
• Check that required properties are included
• Ensure property names are spelled correctly
