Welcome to the Google PubSubHubbub Hub!
This hub conforms to the Pubsubhubbub 0.4 specification.

In addition, this hub conforms to the Pubsubhubbub 0.3 specification with the exception of permanent subscriptions. Because of this you will need to refresh each of your subscriptions periodically, ideally just before hub.lease_seconds elapse since the last successful subscription.

Use this hub with your feeds
Add an //atom:link tag under //atom:feed for Atom feeds or under //rss:rss/channel for RSS feeds. The //atom:link tag should have rel attribute set to hub and href attribute set to https://pubsubhubbub.appspot.com/
Alternatively, your feed can be served with two Link headers:
one with rel attribute set to hub and href attribute set to https://pubsubhubbub.appspot.com/
one with rel attribute set to self and href attribute set to the feed URL of the feed
The above is covered in more detail in the PubsubHubbub 0.4 specification.
Whenever new content is added to a feed, notify the hub. This is accomplished by sending a POST request to https://pubsubhubbub.appspot.com/ with Content-Type: application/x-www-form-urlencoded and two parameters encoded in the body:
hub.mode equal to publish
hub.url equal to the feed URL of the feed that has been updated. This field may be repeated to indicate multiple feeds that have been updated
