Hello @some_one,

DSS API itself is fairly straightforward. It is a web service and after initial authentication, user sends a JSON request and receives a JSON response.

The content received from different web service endpoints is vastly different, and not covered in these developers forum. I would recommend that you start by looking at API Reference Tree and if any content piece is unclear, raise a content help ticket at my.refinitiv.com.

Here are similar questions that can get you started with Corex in DSS -

Hello @some_one ,

I would start with tutorial REST API Tutorial 5: On Demand corporate actions extraction.

This should give a very good idea of how Corporate Actions requests are handled. I would download Postman, import the downloadable collections and run the steps.

You will need to do the same with .NET SDK, and so next I would review .Net SDK Tutorial 1 Connecting to the DSS server and one of the other extraction type .NET tutorials, for example, EOD on Demand, and process the request for Corporate Actions analogously.

I fully agree with @Gurpreet, for the details of Corporate Action extraction, that you will need, DSS REST API Reference Tree is the definitive and most helpful resource.

Thank you both @zoya faberov, @Gurpreet,

this was exactly the starting point I was looking for. The info that DSS is basically just a wrapper around a multitude of different web services helps a lot.

I also did not find the DSS Reference Tree on my own, so this will also be helpful.
