The endpoint read-only property of the PushSubscription interface returns a USVString 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.
