A meaningful interaction has always two directions: sending and receiving. In this part of the post I want to show you how to receive Webmentions from other blogs participating in the IndieWeb.
As Hexo is a SSG it generates static HTML pages. This has the advantage that the pages can be hosted just about anywhere (in my case Github Pages, but also the disadvantage of not having a real backend. Therefore, we need an external service that acts as an Webmention endpoint, where other people can send their webmentions.
Aaron Parecki, co-founder of the IndieWeb, has made a service called webmention.io we can use for free. It is able to convert old-fashioned Pingbacks to Webmentions, supports deleting of unwanted mentions, has a Blocklist for blocking domains, Webhooks for real-time processing and last but not least an API to get all your Webmentions per page or per site.
