Notion

API

API to integrate and automate Notion workspaces

Overview

The Notion API enables programmatic access to Notion workspaces, supporting CRUD operations on pages, databases, blocks, and users. Endpoints include creating/updating content, querying databases for filtered results, retrieving block hierarchies, and managing permissions. Responses are JSON-formatted. Use cases include automating task workflows, syncing Notion data with external tools (CRM, project management), generating custom reports from databases, and embedding Notion content in apps. Authentication uses API keys (internal integrations) or OAuth2 (public apps). Rate limits vary by plan—free tiers have basic limits, while paid plans offer higher throughput.

Example Integration (JavaScript)

script.js JS


fetch('https://developers.notion.com/docs/getting-started')
  .then(res => res.json())
  .then(data => console.log(data))
  .catch(err => console.error(err));
