I want to upgrade our use of the google geocoding api from v2 using geocoding.net to v3, calling it from C# in a method similar to as is described here
Our clients currently use an non-business API key, as they don't need in excess of 25000 geocodes, though they may need to exceed the anonymous 2500 per day limit at times.
According to my google api console at https://code.google.com/apis/console, both my V2 and V3 keys have a limit of 25000 daily requests, however, although the Google Geocoding V3 API appears well documented, I can find no way to pass an API key to it.
Check this article, version 3 has no API keys.
