webmention.io is an open-source project and hosted service for receiving webmentions and pingbacks on behalf of your indieweb site.

Sites currently using webmention.io to receive pingbacks on their behalf:


Accept webmention and pingbacks for any site by adding a simple html tag

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

API to get a list of sites linking to your pages

Example: https://webmention.io/api/links.jf2?target=http%3A%2F%2Fwebmention.io

Converts Pingbacks to WebMentions

You can use webmention.io to handle Pingback requests and send them to you as a webmention.

To use, add an html tag like the following, replacing example.com/webmention with your own webmention endpoint.

<link rel="pingback" href="https://webmention.io/webmention?forward=http://example.com/webmention" />

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.
