API

The Notion API lets developers access and manipulate content in Notion workspaces programmatically. Integrate external apps, automate workflows, and build custom tools.

Definition

An Application Programming Interface (API) is a set of rules and protocols that allows different software applications to communicate with each other. The Notion API exposes endpoints to read, create, update, and delete pages, databases, users, and other resources in a Notion workspace. With the Notion API, developers can connect Notion to external systems, build custom integrations, automate data flows, and extend Notion’s core capabilities. It uses REST architecture with JSON payloads and supports OAuth for secure authorization.

Usage & Context

You use the Notion API when you need to synchronize content between Notion and other tools—such as CRM platforms, analytics dashboards or custom scripts. Common use cases include automatically importing data into a Notion database, generating reports from page content, or triggering workflows based on database changes. Getting started involves obtaining an integration token in Notion’s developer portal, granting the integration access to specific pages or databases, then making authenticated HTTP requests. SDKs and client libraries in languages like JavaScript and Python simplify authentication and API calls.

Frequently Asked Questions

How do I get an API key for Notion?
In Notion’s developer portal, create a new integration. You’ll receive a secret token which you can store securely and use in the Authorization header of your API requests.
What authentication methods does the Notion API support?
The Notion API uses OAuth 2.0 for user-authorized integrations and bearer token authentication for personal or internal integrations.
Are there rate limits?
Yes. Notion enforces rate limits to ensure platform stability. Typical limits are 3 requests per second per integration and burst allowances; consult the API documentation for current quotas.
Do I need coding experience to use the Notion API?
Basic programming knowledge helps, but client libraries and detailed examples make it possible for anyone familiar with REST APIs to start building simple integrations.
Can I update database properties via the API?
Absolutely. The API supports reading, creating, updating, and querying database entries and properties as long as your integration has the required permissions.
