Subscription requests are relayed through hubs, which validate and verify the request. Hubs then distribute new and updated content to subscribers when it becomes available.

Hubs MUST support subscription requests with a secret and deliver authenticated requests when requested. Hubs MUST deliver the full contents of the topic URL in the request, and MAY reduce the payload to a diff if the content type supports it.
