This response is a standard to share data from AAM to AA.
Dests parameter will be present whenever there is any URL destination being returned based on the AA request data set.
As per my knowledge, HR is used for numbering the calls and ID is to show the IDs that have been synced with 3rd party data partner along with the timestamp parameter. Again, these are for internal purposes/usages.
As per your query, you are debugging URL destinations, so is there any particular issue/scenario that you would like to discuss?
