I have the exact same problem like Arul.
I am trying to use Google Maps API on my webpage but when I try to implement the map I've got DeletedApiProjectMapError.
First I went to the Error Messages site after I've tried many ways to include the script, like:
<script src="http://maps.googleapis.com/maps/api/js?v=3&key=API_KEY"></script>
//or
<script src="http://maps.googleapis.com/maps/api/js?key=API_KEY"></script>
//or
<script src="http://maps.googleapis.com/maps/api/js"></script>
and tried to add new API key
on the Dev site but none of them works.
Is it possible that the error isn't on my side but on Google's?
I have found the solution to the problem.
You need to enable both the Google Maps Javascript API, and the Geocoding API.
https://console.developers.google.com/projectselector/apis/library
and
https://console.developers.google.com/google/maps-apis/apis/geocoding-backend.googleapis.com
Afterwards the error was RefererNotAllowedMapError
instead of DeletedApiProjectMapError
, but that was because I was running it on localhost - and it worked on the actual site after I added the domain in Credentials -> Domain Verification
.
