    This feature has been removed from the Web standards. Though some browsers may still support it, it is in the process of being dropped. Do not use it in old or new projects. Pages or Web apps using it may break at any time.

    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));
