What’s Changed

First public release of Publish to FlatPark 🎉

Add five lines to your release workflow and your Linux users get the Flatpak update the same day you publish a release — no tokens, no manifest, no build infrastructure:

on:
  release:
    types: [published]

jobs:
  flatpak:
    runs-on: ubuntu-latest
    # A FlatPark hiccup should never fail your release.
    continue-on-error: true
    steps:
      - uses: flatpark/publish-action@v1
        with:
          app-id: com.example.MyApp

What it does

On release, the action notifies FlatPark, which re-resolves your latest release artifacts and ships the update to its Flatpak repository — where flatpak update delivers it to every installed user.

No secrets required

The webhook trusts nothing at face value: it verifies the app id against FlatPark’s public catalog, confirms this repository is the app’s registered upstream, and checks the tag exists as a real GitHub release — only then does FlatPark trigger its own pipeline with its own credentials. Nobody can use this endpoint to publish releases for a repository they don’t control.

Requirements

Your app must be listed on FlatPark first — open an issue to get it added. Apps shipping official Linux binaries (AppImage, deb, zip, tarball) usually take a day to package.

v1.0.1 fixes the action metadata for Marketplace listing; functionally identical to v1.0.0. Pin @v1 to always get the latest v1.x.
