Can I call an Orchestrator API from my orchestrator?

Can I use this API, using orchestrator on my server?
For example if I want to add a new queue item and I’ve installed orchestrator on localhost, I will call in this way the post request?

https://localhost:443/odata/Queues/UiPathODataSvc.AddQueueItem

Sorry for stupid question, but I’m a new in UiPath and programming !
