WooCommerce Distance Rate Shipping

The WooCommerce Distance Rate Shipping extension requires the use of an unrestricted Google API key, as stated in the documentation, in order to function properly.

This poses a security risk, as unrestricted keys are more vulnerable to unauthorized use and abuse. Google explicitly provides security options to restrict API keys by IP address, HTTP referrer, or by limiting usage to specific APIs — all of which help reduce potential misuse.

I’d like to request an enhancement to the extension that would allow it to work correctly with restricted API keys, following Google’s recommended practices. This would significantly improve the security posture of any store using this feature.
