I have the following use case in my app and was not able to find the right APIs to implement it. Any help is appreciated..
I need to send a notification to a user "A" from my app. The user "A" has installed the app and he may not be on the network when he gets the notification.
It sounds like you want to send a notification from your application to a Yahoo! user, so the user will receive notification via Yahoo! whether they're logged into your application or not. Is that correct?
