# Get a specific class by ID

> You can retrieve (the configuration of) a specific class/documentType to confirm it exists or to parse something from its metadata if you have its `documentTypeId` (class ID).

## Method and API

Play with the API Explorer:

## [GET /documentType/v1/libraries/\{libId}/documentTypes/\{documentTypeId}](/api-reference/document-type)

In the command above:

* `documentType` is the API
* `v1` is the API version
* `libraries` is the top-level resource
* `documentTypes` or class is the nested resource

## Guidelines

### Request

Pass the mandatory class ID (`documentTypeId`) and the library ID (`libId`) of the library the class resides in — both as ***path* parameters** (not in the query string).

<RequestExample>
  ```yaml Sample request theme={null}
  GET https://aodocs.altirnao.com/api/_ah/api/documentType/v1/libraries/Rs4xtue86axGNklquDP/documentTypes/Rs4xuIg86e45fvAsn9L
  ```
</RequestExample>

## Response

The response returns an [ApiDocumentType](/api-reference/document-type) resource, listing the specified class.

**Response fields of note:**

* `id` (of the class)
* `displayName` (of the class)
* `libraryId` (of the library you searched)
* `defaultClass` (whether or not this is the library's default class)
