+#### Get Dataset Available Dataset Types
+
+Returns a list of available dataset types that can be used at dataset creation. By default, only the type "dataset" is returned.
+
+###### Example call:
+
+```typescript
+import { getDatasetAvailableDatasetTypes } from '@iqss/dataverse-client-javascript'
+
+/* ... */
+
+getDatasetAvailableDatasetTypes.execute().then((datasetTypes: DatasetType[]) => {
