Refresh and export webi

Hi,

I can export a webi document as it is but i want to refresh and export a webi document. There is only one parameter with Language = En, which is default. I tried the below in GET, it doesn't work. http://servername:6405/biprws/raylight/v1/documents/1234/parameters?lovInfo=false.

Do i have to use PUT while refreshing?

Any suggestions appreciated.

Thanks,
Arun
