Eikon C# API using Refinitiv.Data not found error.

Hi,

I'm new to Eikon C# API and just started using it from my Visual Studio 2022.

using Refinitiv.Data;
using Refinitiv.Data.Core;

At the library import, I get the foloowing error,

"The type or namespace name 'Refinitiv' could not be found (are you missing a using directive or an assembly reference?)"

I've installed [RefinitivDataAPI] from NuGet and still can't import it.

What's wrong here?

Thank you very much in advance.

Thank you for your quick response. I could solve the library import issue.

Now, I'm looking at the following example and copy paste into my Visual Studio.

https://github.com/Refinitiv-API-Samples/Example.DataLibrary.DotNet/blob/main/src/2.%20Content/2.2-Pricing/2.2.01-Pricing-Snapshot/2.2.01-Pricing-Snapshot.cs

This time, at the

using Configuration;

line I get the following error,

"The type or namespace name 'Configuration' could not be found (are you missing a using directive or an assembly reference?)"

What I'm supposed to do in this case?

It should be the Configuration project in the Example. The project location is at https://github.com/Refinitiv-API-Samples/Example.DataLibrary.DotNet/tree/main/src/Configuration

Thank you again for your reply. It helped me out a lot.

Running the price snapshot example, I get the following error.

What procedure do I need to make the API accessible to the price data?

It looks like an access permission problem.

Hi @sou_u

The Pricing snapshot service is usually reserved for our Wealth clients. To get access to this specific service, you will need to contact your account manager.

Alternatively, you can bypass this and possibly use the streaming services if you are permissioned. Refer to the Streaming Snapshot example.

What's the difference between the Pricing snapshot and Streaming snapshot? Both sounds a kind of snapshot. How different they are?

sou_u

nick.zincone for your reply.

With the Streaming Snapshot example, in turn, I get the following error,

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

Should I contact my account manager for this as well?

Hi @sou_u

Within RDP, there is an endpoint that provides a snapshot of the latest values for a given instrument. This is what you were hitting when you tried your example. The Streaming snapshot communicates with the streaming services within RDP. Using the streaming services, you can request for non-streaming data, also known as snapshot data. When using the streaming API within the library, it also provides the ability to open a stream and perform snapshots within its own managed cache. I would recommend you play with the different Pricing examples to get a better feel what they can do.

Hope this helps.

Hi @sou_u

Yes, you will need to contact your account manager to request that you need pricing data. They will likely have more details on the packaging and features of what you specifically need from the backend.

BTW, I noticed you are requesting your data via the platform (RDP). I just want to confirm this is your requirement - as opposed to retrieving data via our Desktop application (Refinitiv Workspace).

@sou_u

The desktop session requires Eikon or Refinitiv Workspace (a desktop application) to run on the same machine in order to retrieve the data so you need to have an Eikon or Refinitiv Workspace credential. With the platform session, the library connects directly to the Refinitiv Data Platform on Cloud.

The desktop session requires only a client ID (application key) while the RDP session requires a username, password, and client ID (application key).

For more information, please refer to the Refinitiv Data Library for .Net overview page.
