In a previous post I quickly mentioned that this site now has pfefferle’s ActivityPub plugin installed. This plugin implements enough of the ActivityPub and associated protocols to allow a WordPress site to look and behave a bit like a user on an ActivityPub compatible platform including Mastodon and more. By installing the plugin, you can search for an author of a site and then follow them so you can see a stream of their content whenever they post it. From there you can comment on the post and interact with it from within your favorite Fediverse platform.

In this post I quickly describe how to get started with the plugin. To start, install the plugin (https://wordpress.org/plugins/activitypub/) using your usual method for installing plugins. For me, that means adding it to a composer.json file, for you it might mean simply searching for the plugin in your WordPress admin -> plugins screen. Once installed, activate the plugin. That’s it! Your site is now ready to be followed by anyone within the Fediverse network.

The plugin implements the bare minimum required, it seems, so it can be a bit confusing when there are no immediately obvious visual changes to anything. Most of what the plugin does is in the background, inserting routes that are necessary to make the webfinger and ActivityPub protocols work on your site. Don’t worry though, the plugin is working!

To get the search string people need to use to follow your blog posts or pages visit your user profile page. You should see something similar to this near the bottom of the page:

These profile identifiers can be pasted into the search bar of an instance and from there you can follow the author. Simply take the @[email protected] portion that you see and paste it into the search bar of your Mastodon instance. For simplicity, I put this into my Fosstodon profile https://fosstodon.org/@[email protected] This allows people to easily see my profile.

This final step was not immediately clear to me but I found this in my profile it was super easy to then follow myself. Your followers will appear in Users -> Followers. Anyone that replies to a post on the Fediverse will be added as a comment on your site. On my setup, using Akismet, incoming comments were put into spam for some reason.

I have installed this plugin https://wordpress.org/plugins/activitypub/ and activated it which means you can now follow my blog as if it were any other user on the Fediverse network. Pasting @[email protected] into the search bar of your favorite Mastadon (and more) instance will allow you to see posts when I publish them. I will soon stop posting directly on my profile whenever I post content in favor of letting people choose when to get spammed with my content.
