Does Notion have an API?

Yes, Notion offers a comprehensive, production-ready public API that enables developers to connect their workspaces with external applications and automate workflows. First released in May 2021 and now considered stable, the API provides robust access to databases, pages, blocks, users, and comments through standard HTTPS requests. This powerful integration capability transforms Notion from a standalone productivity tool into a connected hub that can sync with your existing tech stack and streamline complex processes.

The API operates through a RESTful architecture with a base URL of `https://api.notion.com/v1` and uses integration tokens or OAuth 2.0 for authentication. You can access comprehensive documentation, interactive references, and official SDKs for both JavaScript and Python, making implementation accessible whether you're a beginner or experienced developer. The authentication process is straightforward: create an integration in your "My Integrations" section, generate a token, and share specific databases or pages with your integration to grant access.

The practical applications are extensive and genuinely useful for streamlining work. You can automatically create database entries from e-commerce orders, sync CRM data with your project databases, or build custom dashboards that pull information from multiple sources. Content creators often use it as a headless CMS backend, while teams leverage it for workflow automation that eliminates repetitive manual tasks. The API supports querying and filtering databases, manipulating page content, and managing user permissions with precision.

However, there are some important limitations to consider. The API includes rate limiting of three requests per second per integration, which means heavy automation requires careful error handling for 429 responses. Additionally, integrations can only access databases and pages explicitly shared with them—a security feature that requires thoughtful permission management. The API doesn't support full workspace exports or advanced features like bi-directional sync without external architecture.

What makes Notion's API particularly attractive is that it's completely free for both paid and free Notion plans, with no additional charges for API access. Combined with active community support and continuous development updates, this creates a solid foundation for building meaningful integrations. Whether you're automating simple tasks or building complex workflows, the Notion API provides the tools you need while maintaining the security and reliability your workspace requires.
