<p>Make your events more discoverable, expand your reach effortlessly while being independent of other (commercial) platforms, and be a part of the growing decentralized web (the Fediverse). With the Event Bridge for ActivityPub Plugin for WordPress, your events can be automatically followed, aggregated and displayed across decentralized platforms like <a href="https://joinmastodon.org" rel="nofollow ugc">Mastodon</a> or <a href="https://gancio.org" rel="nofollow ugc">Gancio</a>, without any extra work. Forget the hassle of managing multiple social media accounts just to keep your audience informed.</p>
<p>This plugin is not an event managing plugin but an add-on to popular event plugins. It extends their functionality to fully support the <a href="https://wordpress.org/plugins/activitypub/" rel="ugc">ActivityPub plugin</a>. With the ActivityPub plugin people can follow your website directly and engage with your events just as they would on social media: liking, boosting and even commenting if you enable it. You retain full ownership of your content. By integrating into your existing setup, it ensures no extra work is needed while enhancing your events’ visibility across the web.</p>
<h4>Supported Event Plugins</h4>
<p>Full support (including importing events from the Fediverse):</p>
<ul>
<li><a href="https://de.wordpress.org/plugins/the-events-calendar/" rel="nofollow ugc">The Events Calendar</a></li>
<li><a href="https://de.wordpress.org/plugins/very-simple-event-list/" rel="nofollow ugc">VS Event List</a></li>
<li><a href="https://gatherpress.org/" rel="nofollow ugc">GatherPress</a></li>
</ul>
<p>Basic support (outgoing events):</p>
<ul>
<li><a href="https://de.wordpress.org/plugins/events-manager/" rel="nofollow ugc">Events Manager</a></li>
<li><a href="https://de.wordpress.org/plugins/wp-event-manager/" rel="nofollow ugc">WP Event Manager</a></li>
<li><a href="https://de.wordpress.org/plugins/wp-event-solution/" rel="nofollow ugc">Eventin</a></li>
<li><a href="https://webnus.net/modern-events-calendar/" rel="nofollow ugc">Modern Events Calendar Lite</a></li>
<li><a href="https://wordpress.org/plugins/event-organiser/" rel="ugc">Event Organiser</a></li>
<li><a href="https://wordpress.org/plugins/eventprime-event-calendar-management/" rel="ugc">EventPrime – Events Calendar, Bookings and Tickets</a></li>
<li><a href="https://wordpress.org/plugins/eventon-lite/" rel="ugc">EventON – Events Calendar</a></li>
</ul>
<h4>How It Works</h4>
<p>With the Event Bridge for ActivityPub WordPress plugin, sharing your events is effortless and automatic! Once you create an event on your WordPress site, it is seamlessly shared across the decentralized web using the ActivityPub protocol.</p>
<div class="embed-vimeo" style="text-align: center;"><iframe loading="lazy" src="https://player.vimeo.com/video/1043105544" width="750" height="422" frameborder="0" webkitallowfullscreen mozallowfullscreen allowfullscreen></iframe></div>
<p>Your events can be automatically delivered to platforms that fully support events, such as <a href="https://joinmobilizon.org/" rel="nofollow ugc">Mobilizon</a>, <a href="https://gancio.org" rel="nofollow ugc">Gancio</a>, <a href="https://friendi.ca" rel="nofollow ugc">Friendica</a>, <a href="https://hubzilla.org" rel="nofollow ugc">Hubzilla</a>, and <a href="https://pleroma.social/" rel="nofollow ugc">Pleroma</a>. These platforms create public event calendars by pulling in events from various sources, including your website. Any updates you make to your events are synced across these platforms—so you only need to manage your events on your own site, with no extra work required.</p>
<div class="embed-vimeo" style="text-align: center;"><iframe loading="lazy" src="https://player.vimeo.com/video/1043104445" width="750" height="422" frameborder="0" webkitallowfullscreen mozallowfullscreen allowfullscreen></iframe></div>
<p>Even platforms that don’t yet fully support events, like <a href="https://joinmastodon.org" rel="nofollow ugc">Mastodon</a>, will still receive a detailed, well-composed summary of your event. The Event Federation plugin ensures that users from those platforms are provided with all important information about an event.</p>
<h4>Features for Your WordPress Events and the Fediverse</h4>
<p><strong>ActivityPub-Enabled Event Sharing:</strong> Your WordPress events are now compatible with the Fediverse, using the ActivityStreams format. This means your events can be easily discovered and followed by users on platforms like Mastodon and other ActivityPub-compatible services.</p>
<p><strong>Automatic Event Summaries:</strong> When your event is shared on the Fediverse, platforms like Mastodon that don’t fully support events will display a brief HTML summary of key details — such as the event’s title, start time, and location. This ensures that even if someone can’t view the full event on their platform, they still get the important info at a glance, with a link to your WordPress event page. Advanced users can create custom summaries via a set of shortcodes.</p>
<p><strong>Improved Event Discoverability:</strong> Your custom event categories are mapped to a set of default categories used in the Fediverse, helping your events reach a wider audience. This improves the chances that users searching for similar events on other platforms will find yours.</p>
<p><strong>Event Reminders for Your Followers:</strong> Often, events are planned well in advance. To keep your followers informed right in time, you can set up reminders that are supposed to trigger the events showing up in their timelines right before the event starts.</p>
<p><strong>External Event Sources:</strong>  This functionality is only available for a subset of the supported event plugins. It enables your WordPress site to act as a hub for displaying events from other ActivityPub profiles, aggregating them into a cohesive calendar view.</p>

<p>Despite Mastodon implying that you would use this plugin for engaging on Mastodon (when you have enabled it for that, see below), the plugin is useful when installed on a plain WordPress.</p>
<p>When you use a Mastodon app, you’ll enter your own blog URL to connect and log in to your blog in the following screens.</p>
<p>You’ll then see just the posts on your blog which can already be useful in a multi-author environment (e.g. private blogs). You can also use that Mastodon app to create simple posts with a message + attachment(s) which can be better suited for your usecase than using the Gutenberg-capable WordPress mobile app.</p>
<p>When used in combination with the <a href="https://wordpress.org/plugins/activitypub/" rel="ugc">ActivityPub</a> (for being followed via Mastodon) and <a href="https://wordpress.org/plugins/friends/" rel="ugc">Friends</a> (for following people on Mastodon or via RSS) plugins, the Enable Mastodon Apps plugin will show you your feed of people you follow and you can follow and unfollow people from within the app.</p>
<p>Be aware that an app will have a post format associated (see the settings page). The plugin will check for the existance of the Friends plugin to find a resonable default (status with Friends plugin, standard otherwise). When you create a post with your Mastodon app, the post format that you selected for the app will be used.</p>
<p>The plugin has been tested with quite a number of Mastodon clients, among them are:</p>
<ul>
<li><a href="https://elk.zone/" rel="nofollow ugc">Elk</a> (Web)</li>
<li><a href="https://pinafore.social/" rel="nofollow ugc">Pinafore</a> (Web)</li>
<li><a href="https://tusky.app/" rel="nofollow ugc">Tusky</a> (Android)</li>
<li><a href="https://tapbots.com/ivory/" rel="nofollow ugc">Ivory</a> (macOS and iOS)</li>
<li><a href="https://mastodon.social/@MonaApp" rel="nofollow ugc">Mona</a> (macOS)</li>
<li><a href="https://github.com/Dimillian/IceCubesApp" rel="nofollow ugc">IceCubes</a> (macOS)</li>
<li><a href="https://getmammoth.app/" rel="nofollow ugc">Mammoth</a> (macOS and iOS)</li>
<li><a href="https://phanpy.social" rel="nofollow ugc">Phanpy</a> (Web)</li>
<li><a href="https://mastodon.social/@MonaApp" rel="nofollow ugc">Mona</a> (macOS and iOS)</li>
</ul>
<p>Many more, see the <a href="https://joinmastodon.org/apps" rel="nofollow ugc">Third-party apps section on joinmastodon.org/apps</a>. Each app might have its quirks, <a href="https://github.com/akirk/enable-mastodon-apps/issues" rel="nofollow ugc">please report an issue when you have troubles</a>. There is also a chance that the API has not been implemented yet (see below.)</p>
<h3>Mastodon API Implementation</h3>
<p>The plugin implements the <a href="https://docs.joinmastodon.org/api/" rel="nofollow ugc">Mastodon API as documented on joinmastodon.org</a>: The OAuth API for logging in (you will see your WordPress login screen when logging in to your Mastodon app, it also works with 2FA plugins) and the REST API for accessing your data.</p>
