PubSubHubbub allows iantest to send realtime notifications when new content is published.

Ever wondered how your application can get realtime updates when RSS feeds are updated?

Use the PubSubHubbub open protocol.

It's a simple protocol built on webhooks which relies on 3rd parties, called hubs. This page is the hub for iantest.

Want iantest's content in realtime?

  1. Send a POST request to, with the following parameters:
    • hub.mode: subscribe or unsubscribe
    • hub.callback: http://domain.tld/your/callback
    • hub.topic: http//
  2. If the hub returns 202, the hub will then check your callback. If it returns anything else, something was wrong and you may want to check the body of hub's the response.
  3. The hub will send a request to your callback URL, to verify your intent: your callback must respond with 200 and must echo the hub.challenge provided by the hub.
  4. When you're subscribed, as soon as the hub sees a new entry in a feed, it will send a POST request with the feed's new entries in the body.
  5. [Recommended]: Provide a hub.secret when subscribing and the hub will send signed notifications, for increased security.
  6. [Optional]: you can also use Superfeedr's track feature to filter content on this hub matching a given keyword, a boolean expression, and even geo-filtering.

This hub supports and recommends the 0.4 spec (last to date), as well as version 0.3.
