To use Google Maps on your site, you must have a Google account and a Google maps API key with the correct credentials.
Acquia Site Studio uses the Maps JavaScript API service for the front-end of your website and the Maps Embed API service for the Acquia Site Studio user interface. The Geocoding API service is used to find the coordinates of an address when input into the Google map marker.
To use a single key, you must add all of these services to your Google maps API key credentials.
To allow for restrictions to be applied to your API keys in adherence to Google’s best practices, you must add Maps JavaScript API and Maps Embed API services to one key and the Geocoding API service to another.
You can register your project and configure your API key credentials in the Google API Console.
