As I mentioned when I was talking about my nascent Webmention setup, the tiny Drupal module I’ve coded up only sends Webmentions, it doesn’t (yet) receive them: for that I’m outsourcing things to Webmention.io.

This was as simple as inserting two lines in the header of each page of this website:

<link rel="pingback" href="https://webmention.io/ruk.ca/xmlrpc" />
<link rel="webmention" href="https://webmention.io/ruk.ca/webmention" />

Once I authenticate myself on Webmention.io as the owner of this site, I have access to a “dashboard” that shows me all my Webmentions; right now there’s only one, resulting from this post on Ton’s blog:

I can also query Webmention.io’s API with a simple GET request, including the target, like:

https://webmention.io/api/mentions?target=https://ruk.ca/content/heres-my-opml

which returns JSON with all the Webmentions sent to that target:

You’ll see that it includes a host of rich metadata about the Webmention, including the contents of the posts with the mention, a snippet that includes the sentence in which the mention appears, and the name and avatar of the author.

Right now I’m not rendering that anywhere on my original post; I’m considering whether the best way to do that is to simply pull the Webmentions in real time via JavaScript or, instead, to set up a webhook at Webmention.io that pushes the Webmentions to a process in my Drupal that converts them to a regular old Drupal comment.
