POST \odata\QueueItems return 405 MethodNotAllowed


In the 2018 API documentation it is a method to add Queue Items to a Queue. I try to use this POST method with the online version of Orchestrator at but I receive a 405 MethodNotAllowed message.

Can this method be enabled? I see that the version of the server is 2018.2.3 which is the latest one.

Thank you
