How to retrieve SAP BO documents from C# .net application based on specific parameters??

Hello,

I have a requirement to pull in SAP BO documents from C# .net application based on specific parameters.

I am able to get the documents by passing the document ID and export to PDF, but not able to pass specific parameters to get the specified document to export.

Code Snippet which I am using to get documents based on ID

var requestGet = new RestRequest(string.Format("/biprws/raylight/v1/documents/{0}", ID), Method.GET);

                requestGet.AddHeader("Accept", "application/pdf");

                requestGet.AddHeader("X-SAP-LogonToken", this._xsaplogontoken);

                var responseGet = this._client.Execute(requestGet);

Any help on this is greatly appreciated.

Thanks

Sushant
