Hi,
To get started using the API, you need to access the Google Developer console.
In the Google Developers Console, follow these steps:
1) Create a new project.
2) Create your API key
When creating your API key, go to Credentials >> Select the “API key” option.
3) Create a “Browser Key”
Name your API key and also add the URL of your website. To make sure your website requests are accepted, make sure you add at least the below two website urls:
*.your-website-url.com/*
your-website-url.com/*
Adding Domain Names
Remember to replace your-website-url.com with you actual website URL.
Do not include https://, https://, or www. in your entries.
Only add one domain entry at a time.
Once done. Create the key and then copy the key into your website under NWM Settings
4) Enable the API Services
In the API Manager click “Overview” on the left side of the screen and then search for the Geocoding API.
Click the Google Maps Geocoding API and Enable the service.
Repeat this process and enable the Google Maps Geolocation API, Google Places API Web Service and also the Google Maps JavaScript API.
This should be it.
You can add the same browser key in both field (Browser Key and Server Key)
Hope this is enough info to proceed.
Thanks
