Post Data into Azure Event Hubs using Web Api Client

gistfile1.cs

private Task<HttpResponseMessage> PostTelemetryAsync(DeviceTelemetry deviceTelemetry)
{
    // Use Event Hubs Signature Generator 0.2.0.1 to generate the token
    // https://github.com/sandrinodimattia/RedDog/releases/tag/0.2.0.1
    // http://fabriccontroller.net/blog/posts/iot-with-azure-service-bus-event-hubs-authenticating-and-sending-from-any-type-of-device-net-and-js-samples/
    var sas = "SharedAccessSignature sr=YOUR TOKEN HERE";

    // Namespace info.
    var serviceNamespace = "YOUR NAMESPACE";
    var hubName = "YOUR HUB NAME";
    var url = string.Format("{0}/publishers/{1}/messages", hubName, deviceTelemetry.DeviceId);

    // Create client.
    var httpClient = new HttpClient
    {
        BaseAddress = new Uri(string.Format("https://{0}.servicebus.windows.net/", serviceNamespace))
    };

    var payload = JsonConvert.SerializeObject(deviceTelemetry);

    httpClient.DefaultRequestHeaders.TryAddWithoutValidation("Authorization", sas);

    var content = new StringContent(payload, Encoding.UTF8, "application/json");

    content.Headers.Add("ContentType", DeviceTelemetry.ContentType);

    return httpClient.PostAsync(url, content);
}

Is the token provided by "YOUR TOKEN HERE" provided by creating a new Sas key in the Azure portal?
