The unregister() method was used to ask the system to unregister and delete the specified endpoint. In the updated API, a subscription is can be unregistered via the PushSubscription.unsubscribe() method.


var request = navigator.push.unregister(pushEndpoint);


A pushEndpoint to be unregistered.


A DOMRequest object to handle the success or failure of the method call.

If the method call is successful, the request's result will be a PushRegistration object representing the endpoint that has been unregistered.


Those objects are anonymous JavaScript objects with the following properties:

A string representing the URL of the unregistered endpoint.
Undefined when unregister.onsuccess is called.


var req = navigator.push.unregister(pushEndpoint);

req.onsuccess = function(e) {
  var endpoint = req.result;
  debug("Unregistered endpoint: " + endpoint );

req.onerror = function(e) {
  debug("Error unregistering the endpoint: " + JSON.stringify(e));
