Data (HTTP) does not return datatype name while "return name" is checked.

Rest test site Datastream Web Service - Test REST Service

Executing "Get Data" with "Properties: Return Name" checked returns datatype name but "DATA (HTTP GET)" returns "null". Please advise how to return by HTTP GET.

Sample:

Thank you for reaching out to us.

I found this page ( https://product.datastream.com/DswsClient/Docs/restapihelp/Data.html ) but it doesn't explain how to set the "Return Name" for data types.

Please contact the Datastream WebService support team directly via MyAccount to verify this.
