@isratrade I didn't realize until you said that that we had proposed trying to use both. The use of `page and per_page` just put more requirement on the application programming against the interface to do more calculation (e.g. where am I at in the collection? Oh, I'm at page * per_page). If we are OK with that as opposed to explicitly stating that to the user where this data is within the collection then works for me. We should NOT try to support two ways of reporting the same data. We should pick whatever we think makes the most sense from an API standpoint for ourselves and for any application's that may use our API and interact with our server. If that requires changes in Katello or Foreman or both, then so be it.
