Querying Device Activation Status

Typical Scenario

After an NA registers a device on the IoT platform, the activation status of the device is false before the device connects to the IoT platform for the first time. When the device connects to the IoT platform for the first time, the activation status of the device is true regardless of whether the device is online, offline, or abnormal. The NA can call this API to query the activation status of the device to check whether the device has connected to the IoT platform.

API Function

This API is used by an NA to query the activation status of a device on the IoT platform to determine whether the device has connected to the IoT platform.

API Prototype

Method

GET

URL

https://server:port/iocm/app/reg/v1.1.0/deviceCredentials/{deviceId}?appId={appId}

Transport Protocol

HTTPS

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.

deviceId

Mandatory

String

path

Uniquely identifies a device. The value of this parameter is allocated by the IoT platform during device registration.

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.

Response Parameters

Status Code: 200 OK

Parameter

Type

Description

deviceId

String(256)

Uniquely identifies a device. The value of this parameter is allocated by the IoT platform during device registration.

activated

Boolean

Indicates whether the device is activated through a verification code.

  • true: The device is activated.
  • false: The device is not activated.

name

String(256)

Indicates the device name.

Request Example

Method: GET
Request:
https://server:port/iocm/app/reg/v1.1.0/deviceCredentials/{deviceId}
Header:
app_key: ******
Authorization: Bearer ******
Content-Type: application/json

Response Example

Response:
Status Code: 200 OK
Content-Type: application/json
Body:
{
  "deviceId": "*******",
  "activated": "*******",
  "name": "*******"
}
