Call this API to retrieve information about a single node based on the operator's unionId and the node ID. ## Request ### Basic information | Field | Value | | ------------------- | ------------------------------------------------------------- | | HTTP URL | `https://api.dingtalk.io/v2.0/wiki/nodes/{nodeId}` | | HTTP Method | GET | | Supported app types | appType-Internal app　appType-Third-party enterprise app | | Permission required | permission-Wiki.Node.Read-Knowledge Base node read permission | ### Request headers | Name | Type | Required | Description | | --------------------------- | ------ | -------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | x-acs-dingtalk-access-token | String | Yes | The access credential for calling this API. Obtain it as follows: - For an internal app, call the [Get the access token of an internal app](/open/development/obtain-the-access-token-of-an-internal-app#) API. - For a third-party enterprise app, call the [Get the access token of an authorized enterprise of a third-party app](https://open.dingtalk.com/document/development/obtain-the-access-token-of-the-authorized-enterprise-1#) API. | ### Path parameters | Name | Type | Required | Description | | ------ | ------ | -------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | | nodeId | String | Yes | The node ID (node dentryUuid). To obtain it, call the [Get the node list](/open/development/get-node-list#) API and use the value of the `nodeId` field in the response. | ### Query parameters | Name | Type | Required | Description | | ------------------- | ------- | -------- | ---------------------------------------------------------------------------------------------------------------- | | withStatisticalInfo | Boolean | No | Whether to retrieve statistical information: - true: Retrieve. - false: Do not retrieve. Default: false. | | withPermissionRole | Boolean | No | Whether to retrieve permission information: - true: Retrieve. - false: Do not retrieve.
