Webmentions not working

See my original request here:


I think there are a couple of things going on here. The first thing I noticed is that there were a couple Webmention requests with a blank target parameter. Micro.blog “accepts” those but they are immediately ignored because the parameter is missing. However, I copy/pasted your curl command and it did send the target through correctly.

There’s another issue, though. Replies from Webmentions need to have a u-in-reply-to class on the link back to Micro.blog so that it knows it’s a reply to the post. So where you have:

<a href="https://micro.blog/Denny/21869905">micro.blog</a>

It should look like this:

<a href="https://micro.blog/Denny/21869905" class="u-in-reply-to">micro.blog</a>

I’ll update the documentation to make this more clear. Thanks!

I suspected that the missing class=“u-in-reply-to” was the culprit.

Thanks for tackling this @manton . I’m a big proponent of IndieWeb technologies.

I’m wondering if crossposting should have a check mark/option to enable the addition of a “source URL” or similar, so that even micro posts that are cross-posted become “eligible” for webmentions?

That would require the platform it’s cross posted to storing that info and then sending web mentions when someone replies to the copy of that post, wouldn’t it?

Maybe? I was thinking about how bridgy only works on long posts (because the URL comes across).

Bridgy requires that link to be in the content-- having some meta data sent to Mastodon/Bluesky/Pixelfed/whatever won’t work if that platform can’t store it and Bridgy can’t access it.

Ahh I see. To clarify: I was not thinking metadata, but end of the post like:

from: [url]

or something like that.

I think a lot of folks would be mad about that because it would dramatically reduce your character count on the cross post for a feature that is not super common.

My understanding is that all Webmentions require a source and target. In any case, the issue here is broken Webmention processing on micro.blog. External Webmention replies to micro.blog comments has worked in the past.
