Subscribing devices to a topic

Request

To subscribe one or more devices to a topic, send a PUT request to:

http://<host>:<port>/mib/v1/topics/{topicName}/devices

Client applications running on WebOS and Tizen Smart TVs must also subscribe to the topic in AWS IoT Core. See the AWS IoT Core documentation for details.

Headers

• Content-Type: application/json

Mandatory fields

• topicName (in both URL and payload) – the name of the topic

• active – set to true to leave the topic active, or to activate it if it is not active. (true is the default.)

• devices – one object for each device to be subscribed, containing at least:

  • deviceId – the unique ID of the device

  • subscriptionStatus – set this to true to subscribe the device.

Example

A request with this payload subscribes the specified devices to a topic (and creates the topic if it does not already exist):

{
  "topicName": "New-Videos",
  "active": true,
  "devices": [
    {
      "deviceId": "59bb5fbbc6f9d5000801ae28",
      "subscriptionStatus": true
    },
    {
      "deviceId": "59bb5fbbc6f9d5000801ae29",
      "subscriptionStatus": true
    },
    {
      "deviceId": "59bb5fbbc6f9d5000801ae30",
      "subscriptionStatus": true
    }
  ]
}

The devices must already be registered with DMM.

Response

A successful request returns an HTTP 200 status.

An unsuccessful request returns an HTTP 404 status if the topic does not exist.
