Fill up the basic information that is required for the webhook The URL should be actually accessible over the internet. Having a localhost here would not work.

There is an open source tool http://requestb.in/ that allows you to receive any web requests to a url given there.

The transaction or block associated with the event you subscribed to will be POSTed to the provided URL. The POST request will also include a X-EventType and a X-EventId HTTP header specifying the type of and id of the webhook which triggered the request. X-Eventtype: unconfirmed-tx X-Eventid: f1cef7d6-cfd9-459c-8ebc-42226ae2b1a7
