    Hi @huachong.li

    You have to use .NET API.

    You can follow this .NET API tutorial.

    Here is the sample request code:

    request = timeSeries.SetupDataRequest("31283H5T8=RRPS")
         .WithView("NDA_RAW")
         .WithAllFields()
         .WithInterval(CommonInterval.Daily)
         .WithNumberOfPoints(10)
         .OnDataReceived(DataReceivedCallback)
         .OnStatusUpdated(StatusUpdatedCallback)
         .CreateAndSend();

    Here is the sample DataReceivedCallback code:

    foreach (IData data in chunk.Records.ToList())
     {
         object closeObject;
         DateTime? date = null;
         double? ask = null;
         if (data.TryGetValue("NDA_DATE", out closeObject))
             date = (DateTime)closeObject;
         if (data.TryGetValue("NDA_ASK_PRICE", out closeObject))
             ask = (double)closeObject;
         Console.WriteLine(date + " " + ask);
     }

    This is the output:
