Our web services, including
[GeoIP web services](https://www.maxmind.com/en/geoip-api-web-services) and
[minFraud services](https://www.maxmind.com/en/solutions/fraud-prevention/overview),
now return the error code `ACCOUNT_ID_REQUIRED` instead of `USER_ID_REQUIRED`
when the account ID parameter is missing.
