Quick Facts

Overview

Notion API is a data & storage apis provided by Notion. Read and write Notion pages, databases, and blocks programmatically. This API is designed to help developers integrate data capabilities into their applications with minimal setup and maximum reliability.

The API supports Bearer Token authentication, ensuring secure access to all endpoints. With a freemium pricing model, Notion offers flexible options for projects of any size, from prototypes to enterprise deployments.

Notion maintains comprehensive documentation, SDKs for popular programming languages, and active community support. The API is built on REST principles, returning JSON responses with standard HTTP status codes, making it straightforward to integrate into existing workflows.

Authentication

This API uses Bearer Token authentication. Send your API key as a Bearer token in the Authorization header of each request. The format is: Authorization: Bearer YOUR_API_KEY.

Always store your credentials securely using environment variables or a secrets manager. Never commit API keys to version control or expose them in client-side code.

Code Samples

Python

import requests
import os

API_KEY = os.environ.get("API_KEY", "YOUR_API_KEY")
BASE_URL = "https://api.notion.com"

headers = {
    "Authorization": f"Bearer {API_KEY}",
    "Content-Type": "application/json"
}

response = requests.get(f"{BASE_URL}/v1/resources", headers=headers)
print(response.status_code)
print(response.json())

JavaScript

const API_KEY = process.env.API_KEY || 'YOUR_API_KEY';
const BASE_URL = 'https://api.notion.com';

const response = await fetch(`${BASE_URL}/v1/resources`, {
  headers: {
    'Authorization': `Bearer ${API_KEY}`,
    'Content-Type': 'application/json'
  }
});
const data = await response.json();
console.log(data);

cURL

    req, _ := http.NewRequest("GET", "https://api.notion.com/v1/resources", nil)
    req.Header.Set("Authorization", "Bearer " + apiKey)
    req.Header.Set("Content-Type", "application/json")
    resp, _ := http.DefaultClient.Do(req)
