I am new to YDN. I am looking for a free service that returns the city and state from a given zipcode. I am trying to use this with the Epicor-Prophet 21 application. Epicor provided the code, but I am geting a 503-error. I have registered as a YDN developer. I have entered the consumer key from my project into:
url.Append("?appid= ");
I presume it may not be free.
Any help would be appreciated.
