 | --- | --- | --- |
 | MessageId |A user-settable identifier for the message used for request-reply patterns. Format: A case-sensitive string (up to 128 characters long) of ASCII 7-bit alphanumeric characters + `{'-', ':',’.', '+', '%', '_', '#', '*', '?', '!', '(', ')', ',', '=', '@', ';', '$', '''}`. | Yes |
 | Sequence number |A number (unique per device-queue) assigned by IoT Hub to each cloud-to-device message. | No for C2D messages; yes otherwise. |
-| To |A destination specified in [Cloud-to-Device](iot-devguide-c2d-guidance.md) messages. | No for C2D messages; yes otherwise. |

 | CorrelationId |A string property in a response message that typically contains the MessageId of the request, in request-reply patterns. | Yes |
 | UserId |An ID used to specify the origin of messages. When messages are generated by IoT Hub, it is set to `{iot hub name}`. | No |
 | Ack |A feedback message generator. This property is used in cloud-to-device messages to request IoT Hub to generate feedback messages as a result of the consumption of the message by the device. Possible values: **none** (default): no feedback message is generated, **positive**: receive a feedback message if the message was completed, **negative**: receive a feedback message if the message expired (or maximum delivery count was reached) without being completed by the device, or **full**: both positive and negative.
