A GitHub Action for sending webmentions after your site builds
Raw
README.md

Send Webmentions with GitHub Actions

Action that uses curl to send your webmentions. It gets the most recent addition to a JSON feed (ideally, your latest post), looks for the value of a key called uri (ideally, your post's permalink) and sends webmentions for it.

The services currently in the file are webmention.app and brid.gy, but any service that can be triggered with a POST request will work fine with this.

This workflow file is run once another GitHub Action named "Build" completes successfully.

Usage

Put it in .github/workflows/.

Set a repository secret called URL with your website's JSON feed, e.g. https://dianoetic.me/feed.json.

You don't need to set GITHUB_TOKEN, this is built-in.
