Notion API

⭐ Beginner's Pick Documents & Productivity / OAuth Advanced HTTPS
Varies by plan (check documentation)

Overview

The Notion API enables you to read and write pages, databases, and blocks in Notion workspaces programmatically. You can build integrations that sync data, automate content creation, or query structured databases. After creating an internal integration, you grant it access to specific pages, making setup straightforward.

💡

Beginner Tip

After creating your integration at https://www.notion.com/my-integrations, remember to share the specific Notion page or database with it — without this sharing step, all API calls will return 404 even with a valid token.

Available Data

Use case: Integrate integrate with notion data into web and mobile applications
Notion data via REST API
JSON-formatted response data
Requires OAuth authentication

Example Response

JSON Response
{
  "status": "success",
  "data": {
    "result": "Data from Notion",
    "description": "Integrate with Notion",
    "timestamp": "2025-01-15T10:00:00Z"
  }
}

Implementation Example

// ⚠️ Note: This URL may be a documentation page. Check official docs for actual API endpoint.
const url = "https://developers.notion.com/docs/getting-started";
// Replace headers or query params with the values required by this API.
const response = await fetch(url, {
  headers: {
  "Authorization": "Bearer YOUR_API_KEY"
  }
});
if (!response.ok) throw new Error(`Request failed: ${response.status}`);
const data = await response.json();
console.log(data);

Common Errors & Troubleshooting

401 Unauthorized The integration token is missing or malformed.
Copy the Internal Integration Token from https://www.notion.com/my-integrations and pass it as a Bearer token.
