I have to use google map. I use below google API script
There some answers saying the JavaScript API needs to be enabled as it is disabled by default. That seems to have changed. It was enabled by default in my account. It did not work anyway. I had to disable and reenable the API, then it worked.
Also it is to be noted that Google says it may take a couple of minutes upon creation until the API key works, that may also have been the thing.
