Our integration with Geocode API stopped working out of the blue. We haven't changed anything on our end, the billing status on Google Cloud is ok, and our website which is using the similar key is still working.
The error we are getting is:
"error_message": "You must use an API key to authenticate each request to Google Maps Platform APIs. For additional information, please refer to Google Maps Platform - Location and Mapping Solutions",
Any idea what could be causing this?
