Registering a Device (Verification Code Mode)
Typical Scenario
Before connecting a device to the IoT platform, an NA must call this API to register the device on the IoT platform and set a unique identification code (such as IMEI) for the device. Then, the device can use the unique identification code to get authenticated and connect to the IoT platform.
This API applies to devices that use LWM2M/CoAP or devices that integrate the AgentLite SDK.
API Function
This API is used by an NA to register a device with the IoT platform. After registration, the device can connect to the IoT platform.

Request Parameters
Parameter |
Mandatory or Optional |
Type |
Location |
Description |
---|---|---|---|---|
app_key |
Mandatory |
String |
header |
Identifies an application that can be accessed on the IoT platform. The value of this parameter is allocated by the IoT platform when the application is created on the platform. |
Authorization |
Mandatory |
String |
header |
Indicates the authentication information for accessing the IoT platform. The value is Bearer {accessToken}, in which {accessToken} indicates the access token returned by the Authentication API. |
appId |
Optional |
String |
query |
Identifies an application that can be accessed on the IoT platform. The value of this parameter is allocated by the IoT platform when the application is created on the platform. Set this parameter to the value of appId of the authorized application. |
deviceInfo |
Optional |
Body |
Indicates the device data. |
|
endUserId |
Optional |
String(256) |
Body |
Identifies an end user. In the NB-IoT solution, this parameter is set to the IMSI of the device. |
imsi |
Optional |
String(1-64) |
Body |
Indicates the IMSI of an NB-IoT device. |
isSecure |
Optional |
Boolean |
Body |
Indicates whether the device is secure. The default value is false. In NB-IoT scenarios, if a registered device is an encryption device, this parameter must be set to true.
|
nodeId |
Mandatory |
String(256) |
Body |
Uniquely identifies a device. The value of this parameter must be the same as the device ID reported by the device. Generally, the MAC address, serial number, or IMEI is used as the node ID.
NOTE:
When the IMEI is used as the node ID, the node ID varies depending on the chipset provided by the manufacturer.
|
psk |
Optional |
String(8-32) |
Body |
If the pre-shared key (PSK) is specified in the request, the IoT platform uses the specified PSK. If the PSK is not specified in the request, the PSK is generated by the IoT platform. The value is a string of characters, including upper-case letters A to F, lower-case letters a to f, and digits 0 to 9. |
timeout |
Optional |
Integer(>=0) |
Body |
Indicates the validity period of the verification code, in units of seconds. If the device has not been connected to the IoT platform and activated within the validity period, the IoT platform deletes the registration information of the device. The value ranges from 0 to 2147483647. If this parameter is set to 0, the device verification code is always valid. (The recommended value is 0.) The default value is 180. The default value can be configured. For details, contact the IoT platform maintenance personnel. |
verifyCode |
Optional |
String(256) |
body |
Indicates the verification code of the device. If verifyCode is specified in the request, the specified verifyCode is returned in the response. If verifyCode is not specified in the request, the verifyCode automatically generated by the IoT platform is returned. Set verifyCode when registering a device that has integrated the AgentLite SDK. The value of verifyCode must be the same as that of nodeId. |
productId |
Optional |
String(256) |
Body |
Identifies the product to which the device belongs. This parameter is used to associate the product model of the device. Either specify this parameter or the following parameters: manufacturerId, manufacturerName, deviceType, model, and protocolType. |

Indicates the manufacturer name. This parameter, together with manufacturerId, deviceType, model, and protocolType, is used to associate the product model of the device. Either specify this parameter, manufacturerId, deviceType, model, and protocolType, or specify productId. |
deviceType |
Optional |
String(256) |
Body |
Indicates the device type. The upper camel case is used, for example, MultiSensor, ContactSensor, and CameraGateway. This parameter, together with manufacturerId, manufacturerName, model, and protocolType, is used to associate the product model of the device. Either specify this parameter, manufacturerId, manufacturerName, model, and protocolType, or specify productId. |
model |
Mandatory |
String(256) |
Body |
Indicates the device model. This parameter, together with manufacturerId, manufacturerName, deviceType, and protocolType, is used to associate the product model of the device. Either specify this parameter, manufacturerId, manufacturerName, deviceType, and protocolType, or specify productId. |
protocolType |
Optional |
String(256) |
Body |
Indicates the protocol used by the device. CoAP and LWM2M are supported. This parameter, together with manufacturerId, manufacturerName, deviceType, and model, is used to associate the product model of the device. Either specify this parameter, manufacturerId, manufacturerName, deviceType, and model, or specify productId. |

psk |
String(32) |
Indicates a random PSK. If the PSK is carried in the request, it is used. Otherwise, the IoT platform generates a random PSK. |
