I’ve added a new article to #IndieWeb TextPattern which covers integrating with Remy’s new Webmention.app service to enable sending of Webmentions for sites which don’t have that capability natively.
“We’ve previously enabled our site to receive Webmentions, but what can we do about sending Webmentions to other sites? Much like we use Webmention.io to handle receiving Webmentions, we’re going to use Webmention.app to handle the sending. And the best bit is, we don’t need to make any modifications to our site!”
