Push a Device Update Notification

Function

After the application calls the API for creating a rule triggering condition (resource is set to device 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 device is updated.

URI

POST /HTTP URL determined when the application creates the device update 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	DeviceCreateOrUpdateNotifyData object	Parameter description: message to push.

**Table 2** DeviceCreateOrUpdateNotifyData
Parameter	Mandatory	Type	Description
body	Yes	QueryDeviceBase object	Parameter description: message content.

**Table 3** QueryDeviceBase
Parameter	Mandatory	Type	Description
app_id	No	String	Parameter description: resource space ID. Maximum: 36
app_name	No	String	Parameter description: resource space name.
device_id	No	String	Parameter description: device ID, which uniquely identifies a device. The value of this parameter is specified during device registration or allocated by the platform. If the value is allocated by the platform, the value is in the format of [product_id]_[node_id]. Maximum: 256
node_id	No	String	Parameter description: device node ID. This parameter is set to the IMEI, MAC address, or serial number. Maximum: 64
gateway_id	No	String	Parameter description: gateway ID, which is the device ID of the parent device. 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 with which it associates. Maximum: 256
device_name	No	String	Parameter description: device name. Maximum: 256
node_type	No	String	Parameter description: device node type. ENDPOINT: indirectly connected device GATEWAY: directly connected device or gateway UNKNOWN: unknown node type
description	No	String	Parameter description: device description. Maximum: 2048
fw_version	No	String	Parameter description: firmware version of the device. Maximum: 256
sw_version	No	String	Parameter description: software version of the device. Maximum: 256
device_sdk_version	No	String	Parameter description: SDK version of the device. Maximum: 256
auth_info	No	AuthInfo object	Parameter description: access authentication information about the device.
product_id	No	String	Parameter description: unique ID of the product associated with the device.
product_name	No	String	Parameter description: name of the product associated with the device.
status	No	String	Parameter description: device status. ONLINE: The device is online. OFFLINE: The device is offline. ABNORMAL: The device is abnormal. INACTIVE: The device is not activated. FREEZED: The device is frozen.
create_time	No	String	Parameter description: time when a device was registered on the platform. The value is in the format of yyyyMMdd'T'HHmmss'Z', for example, 20151212T121212Z.
tags	No	Array of TagV5DTO objects	Parameter description: list of device tags.
extension_info	No	Object	Parameter description: extended information, which can be customized. If this parameter is specified for a child device during device creation, the platform will notify the gateway of the extended information through the MQTT API used for notifying a gateway of new child device connection.

**Table 4** AuthInfo
Parameter	Mandatory	Type	Description
auth_type	No	String	Parameter description: authentication type. Secret authentication (SECRET) and certificate authentication (CERTIFICATES) are supported. If secret authentication is used, fill in secret. If certificate authentication is used, fill in fingerprint. If auth_type is not set, secret authentication is used by default.
secure_access	No	Boolean	Parameter description: whether the device is connected to the platform using a secure protocol. The default value is true. true: The device is connected to the platform using a secure protocol. false: The device is connected to the platform using an insecure protocol. Default: true
timeout	No	Integer	Parameter description: validity period of the device verification code, in seconds. The default value is 0. If the device has not been connected to the platform within the validity period, the platform deletes the registration information of the device. If this parameter is set to 0 (recommended), the verification code is always valid. Note: This parameter is returned only when timeout is modified in the device registration or modification API. Minimum: 0 Maximum: 2147483647 Default: 0

**Table 5** 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.
