How to use Google Maps API keys on your Website

Published 19/12/2019

As of the 22nd June 2016, Google has required all users of their mapping tools to register for a valid API key (Application Programming Interface key). All this means is that Google gives you permission to send a request to their database to retrieve map information.

How do I get an API key?

The Google mapping service is free, but you must have a payment card associated with your account. To check, login to your Google account and click this link to go to the payment method page:

Once you have completed these steps, follow this link to get your API keys:

Type your website address into the ‘Referrer’ box. The given example is:


The stars represent ‘wild cards’ and can have any value. So the first star allows you to use subdomains, and the second star allows any directories and pages on your site to use the API key. So regardless of where the map is on your website, your API key should work. Even if it is:

If you do need to use your API key on another website, you can click the ‘ADD AN ITEM’ link again and add your next web address in there.
