@Janneke I am not sure if this is what you are looking for or not, but only thing I could find that may be it, and it took me quite a while to find too. In your app in Cloud Business, select/edit the object you want to get the ID of, and then right-click and in that menu click the ... object, which brings up submenu, click the Share option there and in the resulting submenu there, choose embed, that will give you the URL which has the ID, but it is not a normal ID that I am used to, but I am hoping that may be what you are looking for in this case. Hopefully you can follow what I have stated here and that is what you were trying to get.
