[5] In August 2015, A version of the Microsoft Android bridge toolset was reported to be leaked and available on the internet along with its documentation.

[6] The leaked toolset required developers to register and use the WNS to send notification data to ported applications, and would not allow for Google Cloud Messaging to be used instead.

Microsoft later discontinued the Android bridge project in favor of continuing support for iOS application porting instead.

The WNS network acknowledges the request, and responds with the device's unique Channel URI Identifier.

If the authentication succeeds, the data to be transmitted is enqueued and then sent to the device from the WNS network using the Channel URI Identifier.
