Call this API to query information about a video conference device. ## API call description Before calling this API, subscribe to the [Device-room binding change](https://open.dingtalk.com/document/development/org-event-overview#) event through [event subscription](https://open.dingtalk.com/document/development/event-subscription-overview#). ## Request ### Basic information | Field | Value | | ------------------- | ------------------------------------------------------------------------------------------- | | HTTP URL | [https://api.dingtalk.io/v1.0/rooms/devices](https://api.dingtalk.io/v1.0/rooms/devices) | | HTTP Method | GET | | Supported app types | appType-Internal app | | Permissions | permission-VideoConference.Conference.Read-Read permission for video conference information | ### Request headers | Name | Type | Required | Description | | --------------------------- | ------ | -------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | x-acs-dingtalk-access-token | String | Yes | The access credential for calling this API. To obtain the value, call the [Get the access token of an internal app](/open/development/obtain-the-access-token-of-an-internal-app#) API. | ### Query parameters | Name | Type | Required | Description | | --------------- | ------ | -------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | operatorUnionId | String | Yes | The unionId of the operator who performs the query. To obtain the value, call the [Query user details](/open/development/query-user-details#) API. | | deviceId | String | No | The ID of the device to query. Obtain the value by subscribing to the [Device-room binding change](https://open.dingtalk.com/document/development/org-event-overview#) event. Specify either `deviceId` or `deviceUnionId`. | | deviceUnionId | String | No | The unionId of the device to query. Obtain the value by subscribing to the [Device-room binding change](https://open.dingtalk.com/document/development/org-event-overview#) event. Specify either `deviceId` or `deviceUnionId`. | ### Request example HTTP ```http theme={"theme":{"light":"github-light","dark":"github-dark"}} GET /v1.0/rooms/devices?operatorUnionId=lmvxxxxx&deviceId=1234&deviceUnionId=lmvUxxxxx HTTP/1.1 Host:api.dingtalk.io x-acs-dingtalk-access-token:xxxxx Content-Type:application/json ``` Java ```java theme={"theme":{"light":"github-light","dark":"github-dark"}} // This file is auto-generated, don't edit it.
