Thanks to @shindakun and the clearly written tutorial at Adding Webmentions To micro.blog I believe I’ve now successfully added Webmentions to this blog. 🤞🏼
@shindakun Curious! I'm using WP with the webmentions plugin, I've just updated the post with more information added to the response property, I wonder if it's sent the update message and if there's any additional info in it.
