Push an Asynchronous Device Command Status Change Notification

Function

After the application calls the API for creating a rule triggering condition (resource is set to device.command.status and event to update), the API for creating a rule action, and the API for modifying a rule triggering condition, and activates a rule, the platform pushes the result to the server specified by the rule when the command status changes.

URI

POST /URL (HTTP) determined when the application creates an asynchronous device command status change notification rule. The AMQP channel does not require the URL.

request_id	No	String	Parameter description: message ID, which is specified by the device or generated by the platform, and is used to trace the service process.
notify_data	Yes	DeviceCommandStatusUpdateNotifyDataV5 object	Parameter description: message to push.

**Table 2** DeviceCommandStatusUpdateNotifyDataV5
Parameter	Mandatory	Type	Description
header	Yes	NotifyDataHeader object	Parameter description: message header.
body	Yes	DeviceCommandStatusUpdate object	Parameter description: message body.

**Table 3** NotifyDataHeader
Parameter	Mandatory	Type	Description
app_id	No	String	Parameter description: application ID. Maximum: 256
device_id	No	String	Parameter description: unique device ID, which is allocated by IoTDA during device registration. Maximum: 256
node_id	No	String	Parameter description: device node ID. This parameter is set to the IMEI, MAC address, or serial number. Maximum: 256
product_id	No	String	Parameter description: unique product ID, which is allocated by the platform during product registration. Maximum: 256
gateway_id	No	String	Parameter description: gateway ID, which uniquely identifies a gateway. The gateway ID is the same as the device ID if the device is a directly connected device. If the device is an indirectly connected device, the gateway ID is the device ID of the directly connected device (that is, the gateway) with which it associates. Maximum: 256
tags	No	Array of TagV5DTO objects	Parameter description: list of tags to be bound to a specific resource. Each tag key must be unique in the tag list. Up to 10 tags can be bound to a resource.

**Table 4** TagV5DTO
Parameter	Mandatory	Type	Description
tag_key	Yes	String	Parameter description: tag key, which is unique for a resource. If the specified key already exists, the value of the existing tag is overwritten. If the specified key does not exist, a new tag is added.
tag_value	No	String	Parameter description: tag value.

**Table 5** DeviceCommandStatusUpdate
Parameter	Mandatory	Type	Description
command_id	Yes	String	Parameter description: command ID, which uniquely identifies a command.
created_time	No	String	Parameter description: UTC time when the command was created. The value is in the format of yyyyMMdd'T'HHmmss'Z'.
sent_time	No	String	Parameter description: UTC time when the platform sent the command. The value is in the format of yyyyMMdd'T'HHmmss'Z'. If the command was sent immediately, the value was the same as the command creation time. If the command had been cached, the value was the time when the command was actually sent.
delivered_time	No	String	Parameter description: UTC time when the device received the command. The value is in the format of yyyyMMdd'T'HHmmss'Z'.
response_time	No	String	Parameter description: UTC time when the device responded to the command. The value is in the format of yyyyMMdd'T'HHmmss'Z'.
status	No	String	Parameter description: status of the delivered command. PENDING: The command is not delivered and is cached on the platform. EXPIRED: The command has expired, that is, the cache time exceeds the value of expireTime. SENT: The command is being delivered. DELIVERED: The command has been delivered. SUCCESSFUL: The command has been executed. FAILED: The command fails to be executed. TIMEOUT: After a command is delivered, no response is received from the device or the response times out.
result	No	Object	Parameter description: detailed command execution result, which is returned by the device in JSON format.
