PushSubscription: endpoint property

The endpoint read-only property of the PushSubscription interface returns a string containing the endpoint associated with the push subscription.

The endpoint takes the form of a custom URL pointing to a push server, which can be used to send a push message to the particular service worker instance that subscribed to the push service. For this reason, it is a good idea to keep your endpoint a secret, so others do not hijack it and abuse the push functionality.

Value

A string.

Examples

js

navigator.serviceWorker.ready.then((reg) => {
  reg.pushManager.subscribe({ userVisibleOnly: true }).then((subscription) => {
    console.log(subscription.endpoint);

    // At this point you would most likely send the subscription
    // endpoint to your server, save it, then use it to send a
    // push message at a later date
  });
});
