Datalumo Sync

GitHub Action that pushes Markdown and docs from a repository into a Datalumo knowledge source.

Use it when your content lives in git. On push, the files are synced. Visitors get search and chat that stay on your content.

Use it

1. In Datalumo, create a source of type API.
2. Create an API key with pages.write and pages.read. Limit it to that source if you can. Read is used to prune pages whose files were removed.
3. Copy your organisation public id (the UUID, not the slug).
4. In the docs repo, add the secrets and this workflow.

name: Sync docs to Datalumo

on:
  push:
    branches: [main]
    paths:
      - "docs/**"
      - ".github/workflows/datalumo.yml"

jobs:
  sync:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: datalumo/github-action@v1
        with:
          api_key: ${{ secrets.DATALUMO_TOKEN }}
          organisation: ${{ secrets.DATALUMO_ORG }}
          source: docs
          path: docs
          base_url: https://example.com/docs

external_id is the path relative to path, without the file extension. install.md becomes install. Nested files keep their folders: guides/install.md becomes guides/install. A later run updates the same pages instead of duplicating them. Files that disappear from the folder are deleted from the source.

Citation URLs are {base_url}/{external_id}, so base_url: https://example.com/docs plus install.md becomes https://example.com/docs/install.

Pin @v1 for compatible updates. Pin @v1.0.0 if you need that exact release.

Inputs

Input	Required	Default	What it is
api_key	yes		Organisation API key with pages.write and pages.read
organisation	yes		Organisation public id (UUID)
source	yes		API source slug or public id
path	no	docs	Folder to sync, relative to the repo
base_url	no		Public docs URL prefix for citations

What it uploads

.md, .mdx, .markdown, .html, .htm, and .txt. It skips .git, node_modules, vendor, and .github.

Title comes from the first # heading, or the file name. After a push, the action kicks indexing. Watch the source page in the dashboard until it says Ready.

An empty folder fails the job instead of wiping the source.
