webmention.app

This is a platform agnostic service that will check a given URL for links to other sites, discover if they support webmentions, then send a webmention to the target.

The notification API is reasonably simplistic:

• POST https://webmention.app/check/?url=:url

  Finds all links in your given URL, discovers those with valid Webmention endpoints, and sends the full webmention notifications.

  The URL should be escaped (though the protocol is not required), and an optional token can be used to avoid the rate limit.

• GET https://webmention.app/check/?url=:url
  Perform a dry run, reporting on all discovered Webmention endpoints

Getting started

Which best describes your site:

• I have an RSS feed
• I have my latest post on my homepage
• I prefer to run command line tools
• I don't want to rely on 3rd party services
• It's complicated, I can make webmention notifications manually
• None of this matches me
