View registrations on Azure Notifications hub

Question

I have created an Azure notifications hub and an API that allows users to register for notifications via the API. This all seems to work without any errors, but I cannot find a way to interrogate the notifications hub for registrations. Can some one tell me how to get a list of all current registrations? Ideally I would just do this in the Azure Portal, but I cannot see anything in there.

Answer 1

In Visual Studio, Server Explorer -> unfold your Azure subscription -> Notification Hubs -> find your hub and double click.

In opened window, there is a Device Registrations tab. You can find all your subscribers there.

In the Azure portal, you unfortunately cannot view your subscribers. But you can send a test broadcast message (just don't specify any tags) and see subscribers below in the Result area.

By the way, if you subscribed any devices, then sent a push notification, but payload was wrong or there were any other kind of issues, such subscription could get removed. So you need to check subscriptions before you sent anything.

Answer 2

You can use NotificationHubClient.GetAllRegistrationsAsync(int) method [1] to get all registrations.
