When do you need a Google Maps API Key? -

following google's illustration - street view service able create simple map myself started. haven't signed api key though.

tutorials i've read such tutsplus - getting creative google maps api says should first step.

that should have line:

<script type="text/javascript" src="https://maps.googleapis.com/maps/api/js?key=your_api_key_goes_here&sensor=true"></script>

but @ to the lowest degree in initial illustration google works fine with:

<script src="https://maps.googleapis.com/maps/api/js?v=3.exp"></script>

i read:

google map api issue. using without api key google map needs api or not?

but don't reply more generalized question. when needed signup api key? limitations face not signing , using ..js?v=3.exp instead? there other thing should using... 1 of 2 questions mentions ...maps/api/js?sensor=false example?

you don't need api key allows monitor application. you'll need api key if want take license.
