Frequently Asked Questions
Common questions about WebSub (FKA. PubSubHubbub)
WebSub provides a common mechanism for communication between publishers of any kind of Web content and their subscribers, based on HTTP web hooks. 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. WebSub was previously known as PubSubHubbub.
W3C WebSub Recommendation WebSub on GitHub WebSub.rocks - WebSub validator
A WebSub Hub is an implementation that handles subscription requests and distributes content to subscribers when the corresponding topic URL has been updated.
A WebSub Publisher is an implementation that advertises a topic and hub URL on one or more resource URLs. This plugin acts as a publisher for your WordPress site.
A WebSub Subscriber is an implementation that discovers the hub and topic URL given a resource URL, subscribes to updates at the hub, and accepts content distribution requests from the hub. This plugin provides a subscriber API for other plugins to use.
The Subscriber API allows other plugins to subscribe to WebSub-enabled feeds using WordPress hooks. See the Subscriber API documentation for detailed examples and usage.
