I am not sure if anyone here has experience in this, but I am working with web services and Json.
I am trying to obtain my current geographic information (city and state) by using the Weather Underground (Weather Forecast & Reports - Long Range & Local | Wunderground | Weather Underground) API (API | Weather Underground). I want to use the geolookup feature (API | Weather Underground) to print out zipcode, city, and state.
I started it, but I am not really sure where to go from here. How should I use the geolookup function? I already created a key.
