PushSubscription: endpoint property

Baseline 2023

Newly available

Since March 2023, this feature works across the latest devices and browser versions. This feature might not work in older devices or browsers.

Secure context: This feature is available only in secure contexts (HTTPS), in some or all supporting browsers.

Note: This feature is available in Web Workers.

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.


A string.


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

    // 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
