Google API keys – What is server key and browser key

This is relevant again now that Google just recently deprecated Browser Keys for its Web Services APIs.

Here are the current definitions:

Server keys

Create and use a server key if your application runs on a server. Do
not use this key outside of your server code. For example, do not
embed it in a web page. To prevent quota theft, restrict your key so
that requests are only allowed from your servers source IP addresses.

Browser keys

Create and use a browser key if your application runs on a client,
such as a web browser. To prevent your key from being used on
unauthorized sites, only allow referrals from domains you administer.

Google API keys – What is server key and browser key

As of now (early 2018), I suspect the difference between server key and browser key is insignificant and only conceptual. Because the web console allows you to apply IP restriction or referrer restriction to any of your key. So, for the same key, you can apply a referrer restriction and then it works as a browser key, and you apply an IP restriction and then it works as a server key. Besides, I dont find specific documentation on server key vs browser key from this official help page.
