Eikon to Workspace API

Hi, i currently use Eikon Desktop and have a C# application that communicates with the API. The following code is used:

EikonDesktopDataAPI.EikonDesktopDataAPI m_edapi = new EikonDesktopDataAPI.EikonDesktopDataAPI();

EEikonDataAPIInitializeResult l_apiInitResult = m_edapi.Initialize();

Right now I'm trying to migrate to Workspace, but the legacy Eikon Desktop is always opened automatically (even if Workspace is already opened) when the Initialize()-part is running. How to tell the API to use Workspace instead of Eikon Desktop?

The API that you are using is Eikon COM which is not available in Refinitiv Workspace.

Therefore, you can't use Eikon COM applications with Refinitiv Workspace.

To retreive data from Refinitiv Workspace, you need to develop a new application with Refinitiv Data Library for .NET or for Python.

You can refer to the Migrating COM API calls to Python article.

Hello @titz.stefan

When migrating from Eikon to Refinitiv workspace, I recommend using the Refinitiv packages to avoid any unintended side effects or limitations. You can find them here:

Refinitiv.Data - NuGet Gallery | Refinitiv.Data 1.0.0-beta5

Refinitiv.Data.Content - NuGet Gallery | Refinitiv.Data.Content 1.0.0-beta5


You will also have to install the Refinitiv Workspace for Desktop.

You can find it here: Refinitiv Workspace - Download

Thank you. On a new computer with Refinitiv Workspace and the packages you provide, I get the following error message when compiling the code:

System.Runtime.InteropServices.COMException: "Retrieving the COM class factory for component with CLSID { {70B3E69B-E207-412E-8A27-E94A01F96728} failed due to the following error: 80040154 Class not registered (exception of HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG))."

I checked the Windows registry, the class ID does not exist. On my other computer, I found the class ID in HKEY_CLASSES_ROOT\EikonDesktopDataAPILib.EikonDesktopDataAPI.

Do I have to Install Eikon Desktop Data API? After looking for it, I found the following link:

https://developers.lseg.com/en/api-catalog/eikon/eikon-data-api/download

There is the note:

"Starting with Eikon version 4.0.36, the Eikon Data API is fully integrated into

Eikon for Windows."

Does it mean that I have to install Eikon Desktop? How do I ensure that the API calls are processed by Workspace?
