All playlist operations are done using the [API playList service] (https://developer.kaltura.com/api-docs/#/playlist).
Not sure what you mean by [quote=“mauligulati, post:1, topic:6250”]
Is there a way to add an image associated with playlist not its content and later extract it using some API (if there is any)?

Can you please elaborate as to what you need done?
Playlists consist of a list of entries, as such, they can contain video, audio or image entries.
As you can see here: https://developer.kaltura.com/api-docs/#/playlist, you should use playList.add() to create a new playlist: https://developer.kaltura.com/api-docs/#/playlist.add
The entries to include are set in playlistContent, XML if the playlistType is dynamic, comma separated list of entry IDs if the playlistType is static or url if the playlistType is mRss
