Updating the admin website

As with the order processor, we can do a small modification to the admin website to call the Notification/PostProductNews action when a new product is created, which will send push notifications to all customers. The procedure for this is pretty much the same, but here, I created a separate helper class to separate the logic from the controller:

private readonly MobileServiceClient _mobileService;

public Notifications()
{
    var mobileServiceUrl = ConfigurationManager.AppSettings["mobileServiceUrl"];
    var mobileServiceKey = ConfigurationManager.AppSettings["mobileServiceKey"];

    this._mobileService = new MobileServiceClient(mobileServiceUrl, mobileServiceKey);
}

public async Task NotifyPostProductNews(int productId)
{
    dynamic data = new ExpandoObject();
    data.productId = productId;

    await this._mobileService.InvokeApiAsync<object, dynamic>("Notification/PostProductNews", data);
}

This method can be called by...
