It took me a while to get all the pieces working but I'm excited that my website now accepts webmentions!
A few months ago I implemented sending webmentions.
Accepting them was a bit tricky because there were a few design decisions I was optimizing for.
In the meantime, you can check out WebmentionFs, an F# library I built for validating and receiving webmentions along with the WebmentionService Azure Functions backend that I'm using to process webmentions for my website.
Also, feel free to send me a webmention. Here's my endpoint for now https://lqdevwebmentions.azurewebsites.net/api/inbox. Check out this blog post where I show how you can send webmentions using F#. You can use any HTTP Client of your choosing to send an HTTP POST request to that endpoint with the body containing a link to one of my articles (target) and the link to your post (source).
Stay tuned for a more detailed post coming on December 21st!
