An apparatus, system, and method for authorizing endpoints of a push pathway for push notifications are described herein. In one example embodiment, an identity provider element authenticates a first endpoint of the push pathway, determines an authentication token associated with the first endpoint, and determines a channel identifier in response to a successful validation of the authentication token associated with the first endpoint. In this embodiment, the identity provider element also authenticates a second endpoint of the push pathway, determines an authentication token associated with the second endpoint, and determines a handle for the push pathway in response to a successful validation of both the authentication token associated with the first endpoint and the authentication token associated with the second endpoint. The push pathway is established for transmission of push notifications from the first to the second endpoint upon establishing the handle for the push pathway.
