Hi, I'm trying to create an item of source type "sent", and am doing so successfully, but the response does not return an ID for that item created.

Is there a reason for this, or perhaps is this a known issue that occurs when certain fields are present in the item being created?

Also, is there a work around so as to obtain the ID of the item after its creation, something better than calling getItemsRequest, and taking the last matching item off the top. If that is the only/best method, what fields are most unique/best to match against?

Thanks for the help and advice!
