When you set the buttons for DisplayActionSheet, you could switch to do something for webservice when the Button is pressed.

private async void ImageButton_Clicked(object sender, EventArgs e)
    {           
        var action = await DisplayActionSheet("ActionSheet: Send to?", "Cancel", null, "Email", "Twitter", "Facebook");
        switch (action)
        {
            case "Email":

                // Do Something when 'Email' Button is pressed

                break;

            case "Twitter":

                // Do Something when 'Twitter' Button is pressed

                break;
            case "Facebook":

                // Do Something when 'Facebook' Button is pressed

                break;              
        }
    }
