Thanks Ludger,
I had already gone through this section on the SDK help document, but it didnt helped me out much in my case of Using REST services using API keys instead of user id and password and also at the same time I want to pass multiple values to the single query parameter in the URL, which is not working when tried to make a GET request to the service.
If I am passing one value for the query parameter call is successful and response is turning out to be "200" and content is also visible. Where as if the multiple parameters are passed in the request then all the values are suppressed with the last feed done to the parameters and only response is available to the last passed value of the request
Please let me know if further details needed on the above and at the same time if any other blog/detailed procedure wise document is available, it would help a lot in knowing much about the REST services.
Regards
Hanu
