Have you received a warning from Google that your Maps API key is unrestricted? This means your key could be used by unauthorized parties — leading to unexpected charges or service interruptions. Google now requires users to apply proper restrictions to prevent misuse.
To secure your key, log into the Google Cloud Console → APIs & Services → Credentials, select your key, and set both application restrictions (limit by website domain, IP address, or app) and API restrictions (only enable the APIs you actually use, such as Routing or Geocoding). Once saved, verify the key works from CDXZipStream and your authorized domains and confirm unauthorized referrers are blocked.
At CDX Technologies, your API key is always encrypted, securely stored, and never exposed in plain text. Our services use the key only within authorized systems, following Google’s security best practices. Together, these measures protect your data, control costs, and keep your location analytics running safely.
