Webmentions
A web standard for notifying a page when another page links to it.
A webmention is a notification between two URLs. If your post links to another person’s post, your publishing tool can tell their site. Their site verifies the link before displaying or recording the mention.
The useful mental model
- The source is the page containing the link.
- The target is the page being linked to.
- The endpoint receives those two URLs.
- The receiver fetches the source and verifies the link exists.
Webmentions can represent replies, likes, reposts and plain references when combined with microformats.
