How to change the playlist owner via API?

1. Open the API console at https://developer.kaltura.com/console/ (Sign In) or  http://www.kaltura.com/api_v3/testme.
   If Testme Console is used, first, you will need to generate a KS session as demonstrated on How to Start a Kaltura Session using the TestMe Console. 
2. Select Session Service > baseEntry.
3. Select Action > update.
4. Enter the desired playlist ID under the entryId (string) field.
5. Select baseEntry (KalturaBaseEntry) > Edit.
6. Enter the desired userId (string).
7. Click Send.

To verify the current playlist owner, generate the following API call: baseEntry > get. View the userId in the output result.
