[Forums] Calling REST Parameter from Jasper Report?

Hello all, 
My situation is the following.  I have a REST call that I want to pass a filter paramater to from Jasper Reports. I unserstand how to create the REST call with the paramater on the Outsystems side (which workd perfectly from the browser), I now need to call the Jasper report using a url with the filter paramater (in this case customer_number) and have Jasper Reports make the REST call using this paramater.  Is anyone else doing anything similar to this?  I have been scowering the Japser Report side but have turned up nothing unless I embed the SQL calls in the Report thus not using REST :-(
Any help would be great!
Thanks in advance!
Chris
