@w4rner My primary site is WordPress which uses both the Webmention and Semantic Linkbacks plugins. My secondary site runs WithKnown and has it built in automatically. I'm curious how you'd use Webmention with IFTTT? I've not heard of that approach before. Can you use it for both sending and receiving, perhaps with some other service like webmention.io? I know that Brid.gy offers some work-around methods to offer Webmention for platforms like Tumblr, WordPress.com, Blogger, and Medium which you might find useful too.
@chrisaldrich On Webmention.app they detail how to use IFTTT to check webmentions you are sending out, though I'm still not sure how to actually make one from a micro.blog post! In terms of receiving webmentions, am looking at webmention.io though I'm not sure I trust the IndieLogin.com web sign-in, it asks for access to my micro.blog account.
@w4rner There's nothing to trust with IndieLogin.com. If I recall correctly it's just implemented IndieAuth, so it's going to take your URL as an input and doublecheck that you're actually logged into your own account before allowing you access to the service. It doesn't take or use your password in any way and you can revoke your login at any time. It's an extension that's built onto OAuth 2.0, so it's really no different than using something like your Twitter or Facebook account to log in, but in this case you're using and hosting the technology with your micro.blog site (or really micro.blog is doing it on your behalf.)
@w4rner As for webmentions, you shouldn't need a third party app for it since micro.blog is sending and receiving webmentions for you already. Now, if you're thinking about adding webmentions to some other service, like Tumblr or a blogging service that doesn't support them natively, then you might want to use something like webmention.io to receive them on your behalf.
@w4rner On the Webmention.app/IFTTT front, that description is a set up for services that don't send/receive webmentions themselves. Every time you publish something on micro.blog with a URL, micro.blog is sending webmentions out for you in the background automatically.
If you had a Tumblr website and wanted to send webmentions, then you might use that Webmention.app/IFTTT set up so that when you posted something on Tumblr, your RSS feed would update with the new post, IFTTT would check the update and trigger webmention.app to send a webmention from your post to any of the URLs that appeared in your post.
@w4rner From what I can tell from the logs, it doesn't look like I received one from your website automatically, but I was able to manually force it to show up: https://boffosocko.com/2020/01/21/using-ifttt-to-syndicate-pesos-content-from-social-services-to-wordpress-using-micropub/#comment-306971. I'm not sure why it wouldn't however. Definitely a question for @manton and the gang.
