Sends Notification of Valid Webmentions via Web Hook
You can have webmention.io send an HTTP notification for each received, valid webmention to a URL of your choice. You may specify a different endpoint for each domain.

Optionally, you can configure a "callback secret" so that your HTTP endpoint can verify that the notification was sent by webmention.io.

How to Use
If you want to use this right now, you can sign in on the home page https://webmention.io

You are more than welcome to use the pingback->webmention conversion service as described above. Or you can install this on your own server from the source code on Github.
