102: Subscriber Sends Additional Parameters

If your hub is a "public hub", e.g. it is a standalone service that can be used by any publisher, then you can use this option. If your hub is integrated with the publishing software, choose the other tab.

Provide the URL of your hub below. Once you do so, a sample blog will be generated that points to your hub, and this test will attempt to subscribe to updates about the blog from your hub.

Make sure your hub allows subscriptions for this domain. (Some hubs will require registration before a new domain is allowed to use them.)

Enter a topic URL that advertises its hub as the hub you want to test. You will be responsible for triggering the hub to send notifications to the subscriber.

This subscriber will include some additional parameters in the request, which must be ignored by the hub if the hub doesn't recognize them.
