When i register my track to royalty collecting online company, how do i communicate it with AudioJungle?

Here you will find three articles about AJ vs PRO and CID. There is everything you have asked about.

BTW PRO can and even must collect broadcast royalties from tv, radio, etc. even though your client bought sync license on AJ. They collect it from a broadcaster, not from your client. It is explained in the second article.
