# Testing ActivityPub federation on the forum **URL:** https://discuss.privacyguides.net/t/testing-activitypub-federation-on-the-forum/27422 **Category:** Announcements **Created:** 2025-05-09T00:55:06Z **Posts:** 28 ## Post 1 by @jonah — 2025-05-09T00:55:06Z Discourse now supports ActivityPub as a method of accessing posts, and we’re testing this out with the #General > News category and our announcements. You’ll be able to find out about Mastodon posts and even reply to posts from Mastodon and they’ll show up here! Hint: If you have a Mastodon account, link it to your forum account at [https://discuss.privacyguides.net/my/preferences/activity-pub](https://discuss.privacyguides.net/my/preferences/activity-pub). That way if you reply or like a post on Mastodon, it will perform the reply/like here with your forum account :wink: **See [https://discuss.privacyguides.net/ap/about](https://discuss.privacyguides.net/ap/about) for details.** If you notice anything odd or have any questions, this is the place for them! :backhand_index_pointing_down: --- ## Post 2 by @jonah — 2025-05-09T00:55:30Z --- ## Post 3 by @anon19006164 — 2025-05-09T05:06:11Z [@jonah](https://discuss.privacyguides.net/u/jonah) cool :) --- ## Post 4 by @RokeJulianLockhart — 2025-05-09T07:20:37Z > [@jonah](#): > > If you have a Mastodon account, link it to your forum account at [Privacy Guides Community - The largest personal privacy forum - Ask questions, find consumer privacy tools, and stay informed](https://discuss.privacyguides.net/my/preferences/activity-pub). @jonah, when I enter `rokejulianlockhart@mastodon.social` with the type set to “Mastodon”, I see: > An error occurred: You supplied invalid parameters to the request: `Discourse::InvalidParameters` Is anyone else able to authorise a `mastodon.social` account? --- ## Post 5 by @RokeJulianLockhart — 2025-05-09T07:31:20Z Ah, ignore me. You’re solely meant to enter the domain. I’d ignored the placeholder text. --- ## Post 6 by @pinkandwhite — 2025-05-09T07:39:09Z linking to an Akkoma account doesn’t seem to work, throws up an insufficient permissions message even though it should be authorised lol --- ## Post 7 by @whoami4 — 2025-05-09T08:53:33Z [@jonah](https://discuss.privacyguides.net/u/jonah) done. I am curious how it will work :) --- ## Post 8 by @anon39279085 — 2025-05-09T09:01:58Z Weirdly I don’t see the reply over ok your mastodon (also Activists much? :wink: But hey I respect your mastodon so you get a follow ) However if you see it on your side, works. edit: MB! I see it on the floss.social instance --- ## Post 9 by @whoami4 — 2025-05-09T09:16:10Z [@GorujoCY](https://discuss.privacyguides.net/u/GorujoCY) Hey, I see it, nice! But I didn't get a notification for it. I noticed only because of the follow. Thanks btw and right back at ya (curious if i see all your forum posts on my mastodon feed now) :) And it seems the sync is fast, I tried several edits and by the time I clicked on the forum tab it was already there. --- ## Post 10 by @anon23565824 — 2025-05-09T13:03:30Z [@jonah](https://discuss.privacyguides.net/u/jonah) hey, thats awesome! --- ## Post 12 by @anon36458186 — 2025-05-09T15:31:29Z [@jonah](https://discuss.privacyguides.net/u/jonah) Welcome to fedi. --- ## Post 13 by @davidcollini — 2025-05-09T15:42:21Z Just linked my accounts, it’s great seeing the fediverse grow🙌 --- ## Post 14 by @RokeJulianLockhart — 2025-05-09T16:42:39Z @jonah, two more things of _genuine_ note: 1. I can somehow authenticate with my own account, _here_: 2. Entering capital letters also causes `Discourse::InvalidParameters`, despite DNS being case-insensitive. Is this for Discourse Meta, though? --- ## Post 15 by @PhobosYeimos — 2025-05-09T16:50:35Z I didn’t expect Discourse to be able to federate. As a fedi lover, I truly appreciate this. --- ## Post 16 by @anon39279085 — 2025-05-09T19:06:59Z it could for a while but I guess discourse made it stable which is amazing honestly, I personally feel more forums should federate like this but that’s just my opinion --- ## Post 17 by @Brisingr05 — 2025-05-14T05:47:02Z [@jonah](https://discuss.privacyguides.net/u/jonah) Cool :blobcatcool: . EDIT: I guess Mastodon emojis don't work on Discourse hehe. --- ## Post 21 by @rescuer-phoniness — 2025-05-24T07:01:39Z Does this work with lemmy? --- ## Post 22 by @win11.shading291 — 2025-05-29T16:34:02Z Can this be explained further? Does it mean that all the posts here are mirrored on Mastodon? --- ## Post 23 by @jonah — 2025-06-11T01:39:01Z It’s not mirroring. It’s just a different way to access posts. You have to think of ActivityPub like HTTP: it’s simply a protocol to access information. We’ve always published the forum with HTTP of course, and now it is published with ActivityPub as well (in certain categories). You use a web browser to access HTTP content, and you use an ActivityPub client to access ActivityPub content. Mastodon is one example of an ActivityPub client you could use to read posts, yes. --- ## Post 24 by @TheManWithNoPlan — 2025-06-11T01:55:48Z Hello. There may be an issue with the settings of your forum software. It looks like this is a reply to a post. I have made an acount there, some time ago, but have never contributed so I assume there is an issue. Good luck with the troubleshooting and have a good rest of the day. --- ## Post 26 by @jonah — 2025-06-11T02:08:22Z Thank you for reporting. The forum is configured to automatically notify people of new posts in #Announcements, #Announcements > Articles, and #Announcements > Videos. Unfortunately it appeared to also notify people of every _reply_ to those topics (like this one) as well. **This has now been updated/fixed** , so that you will only receive notifications of the first posts for new announcements, and not the replies :slight_smile: If you are logged in you’ll simply receive these notifications in the browser, but if you are away for some period of time then you may also receive email notifications about them. If you want to stop being notified of announcements, even just the first posts, you will have to adjust your settings here to remove announcements from the “Watching First Post” categories: [https://discuss.privacyguides.net/my/preferences/tracking](https://discuss.privacyguides.net/my/preferences/tracking) If you want to change your email preferences more generally, you can do so here: [https://discuss.privacyguides.net/my/preferences/emails](https://discuss.privacyguides.net/my/preferences/emails) --- ## Post 27 by @anon92357554 — 2025-06-11T02:40:10Z Can’t get it to work w/ Sharkey, might not be available outside of Mastodon perhaps? --- ## Post 28 by @win11.shading291 — 2025-06-11T03:21:03Z Thanks, this post made me realize I hadn’t fully grasp what federation really meant, but this cleared things up for me. --- ## Post 29 by @system — 2025-07-11T03:21:56Z This topic was automatically closed 30 days after the last reply.
