   (Remember to restrict the API key before using it in production.)

Restrict API Key

Restricting API keys adds security to your application by ensuring only authorized requests are made with your API key. We strongly recommend that you follow the instructions to set restrictions for your API keys. For more information, see API security best practices.

2. Go to the Google Maps Platform > Credentials page.
