Hey guys,

I'm developing an application in which I'm using HERE Maps API. I'm trying to get a list of Petrol Stations from the user current location. I'm using the following URL:

Code:
http://places.nlp.nokia.com/places/v1/discover/search?at=28.6100,77.2300&q=petrol&size=20&tf=plain&app_code=XXXXXXXXXX&app_id=XXXXXXXXXXX
I'm getting a valid response if I'm viewing it on my laptop's browser, however, when I'm debugging my application code, I'm receiving

Code:
{"message":"Missing authentication parameters","status":401}


Could anyone please let me know where I'm going wrong or what is it that I need to change?



P.S. If you'd like to test, please replace the app_code and app_id parameters.
