About notionapi

This is an unofficial, Go API for https://notion.so. Mostly for reading, limited write capabilities.

It allows you to retrieve content of a Notion page in structured format.

You can then e.g. convert that format to HTML.

Note: official Notion API is still in beta and not as capable as this unofficial API.

• API docs: https://pkg.go.dev/github.com/kjk/notionapi

You can learn how I reverse-engineered the Notion API in order to write this library.

Real-life usage

I use this API to publish my blog and series of programming books from content stored in Notion.

Notion serves as a CMS (Content Management System). I write and edit pages in Notion.

I use custom Go program to download Notion pages using this this library and converts pages to HTML. It then publishes the result to Netlify.
