Hi @benny_1,
It is most certainly is possible. We have an API called eventNotification which you can use to hook into Kaltura for various events, one of which being when an entry is ready. It has to sub categories: email and HTTP. Email will simply email you when the event happens, HTTP will pass along an array of the relevant parameters [entry_id, status, etc] to whatever URL you provide.
Please see here:

For code examples.
