Experimental utility to convert OpenAPI definitions to Notion Pages via the Notion API.

Usage

• Create an internal Notion integration and get the secret token
• The Target Notion page needs to be shared with the integration
• The Target page needs to be contained in a notion Wiki (to be able to add properties)
• Create a property in the Wiki named exactly OpenAPI-Generated
• The OpenAPI definitions need to have a unique title which will be used as the page title
• Run the program locally or as a GitHub action

Options

OpenAPI extensions:

• x-notion-flatten : Flatten the object structure instead of linking to schemas (default false).
• x-notion-header: Hide or show the page header (default true).

Config File

The config file is a YAML file with the following structure:

generateCollection: '/path/to/collection.yaml'
template: 2
pages:
  - notionPageId: aaaaaaaaaaaaaaa
    apiFolder: path/to/docs
  - notionPageId: bbbbbbbbbbbbbbb
    apiFolder: path/to/other

• pages: list is a list of Target Notion pages and the path to the folder containing the OpenAPI definitions.
• generateCollection: is an optional path to a collection file that will be generated with all the input files.
• template: is an optional integer to select the template to use. Default is 2. (1 or 2)

GitHub Action

It is necessary to use depth 0 to correctly evaluate files changed time

jobs:
  openapi-to-notion:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout code
        uses: actions/checkout@v4
        with:
          fetch-depth: 0
      - name: Build API docs
        uses: PaoloConte/openapi-to-notion@v1.6.2
        with:
          notion-token: ${{ secrets.NOTION_TOKEN }}
          config: |            
            pages:
              - notionPageId: aaaaaaaaaaaaaaa
                apiFolder: path/to/docs
              - notionPageId: bbbbbbbbbbbbbbb
                apiFolder: path/to/other
