Failed to open OMM stream - streaming services are unavailable

this is on behalf of a client, Powerseller:

Our existing side-by-side interface with Eikon allow us to start the Eikon environment, when it is not already open, with Eikon API .Net calls like these:

• EikonDesktopDataAPI.EikonDesktopDataAPI.IEikonDesktopDataAPIEvents_OnStatusChangedEventHandler()
• EikonDesktopDataAPI.EikonDesktopDataAPI.Initialize()

In the Workspace API documentation and tutorial examples, I cannot find any reference to an API call to start Workspace, if it is not already open. Right now, if Workspace is not open, I get the message from the errTxt variable.

{

"Error": "Failed to open OMM stream - streaming services are unavailable. Verify log details and ensure you have permissions."

}

We would prefer to be able to start Workspace automatically, like we do in Eikon, if it is not currently open. Without this functionality we would require the user to manually start Workspace before initiating our pricing request from the PowerSeller application.

Are there any API calls for Workspace to initialize/start the Workspace environment similar to what we used in Eikon?
