Why Google places API key not works?
<p>I want to use Places API for show near by location.I have added service for it and use below url.
<a href="https://maps.googleapis.com/maps/api/place/search/json?location=22.7253,75.8655&amp;radius=500&amp;sensor=true&amp;types=bar&amp;key=mykey" rel="nofollow">https://maps.googleapis.com/maps/api/place/search/json?location=22.7253,75.8655&amp;radius=500&amp;sensor=true&amp;types=bar&amp;key=mykey</a> </p>

<p>It returns the following error. 
{  "error_message" : "This IP, site or mobile application is not authorized to use this       API key.",
     "html_attributions" : [],
     "results" : [],
     "status" : "REQUEST_DENIED"
}</p>
