Is Google Maps Api V3 Requires Key?

I developed one website in google maps api V2, now management is saying V2 is deprecated and convert in to V3. While googling the V3 i didn't see any api key? then how it works? ht

Solution 1:

Google Maps API v3 can be used both with and without a key. You can read this post for clues how to migrate your application. Basically

The second step in the migration process consists in renaming api calls and objects. The renaming follows the following pattern:

GMarker -> google.maps.Marker

GOverlay ->google.maps.Overlay

GEvent -> google.maps.Event …

Solution 2:

Google maps api v3 doesn't need a key like v2. You are encouraged to use v3 because of the support for devices like iphone and android.

Googe maps api v3 has been implemented using modified MVC framework. .

Any state changes of an MVC object (such as a map) for example, are handled through setters and getters of a particular format. As well, all state of the MVC objects are stored as properties of that object, and all observation of state changes through event handlers is of a particular format as well.
